Disable prompts while installing a Debian package
(3 answers)
Closed 6 years ago.
I've exported a completely done VM image from Virtualbox and am trying to do an unattended setup with a script I created. So, when I get to apt-get upgrade this window eventually pops up which is making my script hang. The user should not have to do interact with the setup at all.
How can I get past this automatically for the user? Or just ignore the grub update?
Thanks!
Try this:
apt-get -y upgrade
and if that does not work, try this:
DEBIAN_FRONTEND=noninteractive apt-get -y upgrade
Please note: using the code above would just simply tell the system to choose the default answer for each question (do you always want the default answer? think about that).
Edit: there's one more situation in which the system could still ask the user to interact with the upgrade: if you manually modified a configuration file of a program that will be updated, the system may halt the upgrade and ask you whether you want to keep the old configuration file or overwrite it with the new configuration file. The code below would avoid the system asking the user to make this choice:
DEBIAN_FRONTEND=noninteractive apt-get -y -o DPkg::options::="--force-confdef" -o DPkg::options::="--force-confold" upgrade
Regarding the configuration file, the code above would instruct the system to:
1) Check if the package being installed specifies by default that the new configuration file should be installed - if that is the case, then the new configuration file will be installed and overwrite the old one.
2) If the package being installed does not specify by default that the new configuration file should be installed, then the old configuration file would be kept - that is very useful, specially when you customized the installation of that package.

I want to install openjdk on ubuntu.
I found two ways to install it.
The first is typing "sudo apt-get install openjdk-8-jdk" on terminal.
The second is downloading the binary file such as *.tar.gz and then unpack the file and set environment variables JAVA_HOME&PATH.
So, is there any difference between this two methods?
I mean, will it cause different results?
Thanks a lot.
With the first approach, the installation is controlled by Debians Apt package manager and will receive updates, with the second one you will have to do that manually.
It will probably not end with different result.
On linux distributions you have what is called a packet manager : Yours (and on almost every ubuntu) is APT.
So the main difference is that when you use apt, you can "trust more" what you are downloading, because hopefully, content in apt are check.
However, because of this checking, apt isn't every time up-to-date, and it may induce some difference in version.
However, in my opinion if you doesn't want to duplicate file or pollute your system, you may want to choose either one option and stay with it : if you use apt, use apt to update, if you download it manually keep updating it manually.
I personally prefer to use apt when possible.
I wanted to install msttfonts on CentOS 7. Following this guide everything goes fine, until I got to run the command:
# rpmbuild -bb msttcorefonts-2.5-1.spec
The system then throws this message:
cabextract is needed by msttcorefonts-2.0-1.noarch
It is pretty obvious that I've to install cabextract, so I did. By Downloading source from here, extracting, and then ./config... make... make install... (you know guys: all the routine). And I confirm the installation was successful with
# cabextract --version
Which answers with
cabextract version 1.6
So, I go back with my command rpmbuild... But the system stills answer me
cabextract is needed by msttcorefonts-2.0-1.noarch
And now, the questions:
What I'm doing wrong? Do I need to reboot the server? Is there a kind of command to tell the server "hey! this cabextract thing is already installed"?
... and well, while I was writting this question, I could resolve it thanks to this post. So I just leave this question just for further reference.
Thanks in advance.
You need to install the cabextract package (by running yum install cabextract).
The message you are seeing is a dependency error: the msttcorefonts-2.5-1.spec file lists a dependency on cabextract, but because you have installed it from source there is no information about it in the local packages database.
I'm using vagrant shell provisioning here.
I've installed on my vm Node.js along with many other packages.
I want to avoid running parts in my provisioning script when I don't need them.
For example - I already successfully installed via my script Node.js & nginx, so when I want to add additional packages like mysql or redis, I want to add it to the script, I want to run the script to test that it runs properly, but I DO NOT want to re-install Node.js or nginx again...
I need a simple conditional statement that would detect if a package is already installed, and install it only if it is not already installed.
Is there a generic check or will it be different from package to package?
Thanks
Ajar
dpkg -s <pkg-name> 2>/dev/null >/dev/null || sudo apt-get -y install <pkg-name>
This should be what you're looking for.
What's going on here:
This is a conditional assignment of the form <condition> && <value if true> || <value if false>
The first part of the expression uses dpkg to check to if the package is installed, suppressing the output. The second part is evaluated if the condition returns false. The "true" case is omitted.
This dependes on the Linux distribution you are using. Usually, a package manager comes with some kind of mechanism to skipp already installed packages.
For Ubuntu, this is built in - running apt-get install nodejs with Node.js already installed will not reinstall it; it will skip the target (unless there is new version available)
For ArchLinux, you can add run pacman -Sy node --needed to skip already installed packages.
A platform-independent mechanism would be to check if the executable (or any other known file for that package) exists. In Bash, you can do:
which node > /dev/null && echo "Yup, this is installed"
(the > /dev/null part supresses which's output - it prints the path where the found executable resides; we do not care about that, we only want to know if it is installed)
If you want to avoid writing custom Bash scripts for such basic checks I can recommend that you configure your boxes with tools dedicated for exactly what you are trying to achieve. The usual suspects here are:
Ansible
Puppet
Chef
CFEngine
All of these are supported by Vagrant so integrating them should not be a problem. You can find detailed guides on integrating these into your existing Vagrant recipe here.
PS. For a simple exapmle you can check out my Ansible provisioning recipe for Banana Pi machine running ArchLinux (note: it does not really follow best practices, but it might be a good starting point). There are many examples available online, check them out, too.
I am running PhpStorm on Linux Mint installed in /opt. PhpStorm is notifying me that there is an update available (8.0.3), but then it tells me it doesn't have write permission to apply the update, and that I should run it as a privileged user to update it.
If I run phpstorm.sh as root/sudo it asks for license info and looks as though it's running the installer rather than the program. PhpStorm is licensed when I run it from the desktop.
So how can I run updates?
I had the same issue and was able to change ownership of the PhpStorm folder to get it to work. Assuming your username is newownername and PhpStorm installation is located in /opt/phpstorm, the command should look like this:
chown -R newownername /opt/phpstorm
Note that you should change username and path to appropriate values.
No need (and not recommended) to change the ownership or the permissions of the opt/phpstorm directory. In fact, the error message returned says exactly what you should do: run it as a privileged user to update it.
After exiting PHPStorm, you can run it as a privileged user using the following instructions
sudo updatedb && sudo locate phpstorm.sh
sudo /path/to/phpstorm.sh
The first instruction updates the locate database and returns the location of the phpstorm executable in your computer.
Use the returned location as the path in the second instruction.
When starting PHPStorm as root, it will start with the default settings. It might even ask you if you want to apply your license... No need to change any of this: the default settings and running PHPStorm in evaluation mode will work just fine. After it starts, check for updates in the menu Help and apply them normally. PHPStorm might restart once again as root. Just close it once more and restart normally. When restarting as your user, you'll be given the ability to select your normal settings (usually stored in your user's directory: the path will be suggested). Accept and continue. PHPStorm will start with all your preferences and settings restored and properly upgraded.
If plugin updates are required, you can update them normally. No need to do it using root.
This solution is recommended by JetBrains. Changing the ownership or the permissions of the opt/phpstorm directory is not recommended and in fact pointed as incorrect by Jet Brains, as you can verify on their answer regarding the process of upgrading a similar product: Fixed: PyCharm automatic update fails on Linux due to permissions.
sudo chown -R $USER:$USER /opt/PhpStorm* , worked for me.
JetBrains are publishing their entire IDE portfolio as snaps, including PHPStorm. Snaps work on all supported versions of Ubuntu, including 14.04 and on Linux Mint 17.x and 18.x.
Some of the advantages of the JetBrains snaps are that they are always up to date, will automatically stay updated and are very easy to install.
To install PHPStorm in Ubuntu or Linux Mint:
sudo apt install snapd
sudo snap install phpstorm --classic
I am working on AWS services. I have an ec2 ( centos ) instance. I need to configure SQL*Plus client on this centos machine.
The server with whom I want to connect is at some remote area. The server version is oracle-se(11.2.0.2)
How can I get the client installed on the CentOS machine?
Go to Oracle Linux x86-64 instant clients download page
Download the matching client
oracle-instantclient11.2-basic-11.2.0.2.0.x86_64.rpm
oracle-instantclient11.2-sqlplus-11.2.0.2.0.x86_64.rpm
Install
rpm -ivh oracle-instantclient11.2-basic-11.2.0.2.0.x86_64.rpm
rpm -ivh oracle-instantclient11.2-sqlplus-11.2.0.2.0.x86_64.rpm
Set environment variables in your ~/.bash_profile
ORACLE_HOME=/usr/lib/oracle/11.2/client64
PATH=$ORACLE_HOME/bin:$PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib
export ORACLE_HOME
export LD_LIBRARY_PATH
export PATH
Reload your .bash_profile by simply typing source ~/.bash_profile (suggested by jbass) or Log-out user and log-in again.
Now you're ready to use SQL*Plus and connect your server. Type in :
sqlplus "username/pass#(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.2.1)(PORT=1521))(CONNECT_DATA=(SID=YOURSID)))"
The solution by #ChamaraKeragala is good, but it is unnecessary to logout/login. Instead type:
source ~/.bash_profile
For everyone still getting the following error:
sqlplus command not found
The original post refers to a set of environment variables, the most important of which is ORACLE_HOME. This is the parent directory where the oracle binaries get installed.
Depending on what version of oracle you downloaded you'll have to change the ORACLE_HOME accordingly. For example, the original question's ORACLE_HOME was set to:
ORACLE_HOME=/usr/lib/oracle/11.2/client64
My version of Oracle happens to be 12.1, so my ORACLE_HOME is set to:
ORACLE_HOME=/usr/lib/oracle/12.1/client64
If you are unsure of the version that you downloaded, you can:
cd /usr/lib/oracle after the installation and find the version.
Look at the RPM file oracle-instantclient12.1, where the bolded bits would refer to the version number.
There's a good blog post[1] on $subject. setup oracle client in ubuntu with minimum effort. Following are the main steps on how to step up the client.
In my case, I was installing rpm files using alien package.
Install alien and related packages
sudo apt-get install alien
Install oracle client packages using alien.
sudo alien -i oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64.rpm
sudo alien -i oracle-instantclient11.2-sqlplus-11.2.0.3.0-1.x86_64.rpm
In my opinion these two steps are the easiest way to install oracle client rpm's on your ubuntu system. (I'm not going to mention about export oracle specific variables as it's already clearly explained in above answers)
Hope it helps someone.

For any one who is using proxy, you'd need to add an extra line to the bash profile. At least this is what made it work for me. I'm using cntlm.
export no_proxy=
Install via zip (tried with 12_2)
First of all there is no need to set ORACLE_HOME.
Simply download the .zip files from here starting with the first one Basic: followed by SQL*Plus: and any additional zips you may need.
Extract them all under /opt/oracle
You will then have a directory: /opt/oracle/instantclient_x_y
On ubuntu I had to do also:
sudo apt install libaio1
To run:
# This can be also done by adding only the path below in: /etc/ld.so.conf.d/oracle-instantclient.conf
export LD_LIBRARY_PATH=/opt/oracle/instantclient_x_y:$LD_LIBRARY_PATH
# This can be added in ~/.profile or ~/.bashrc
export ORACLE_HOME=/opt/oracle/instantclient_x_y
/opt/oracle/instantclient_x_y/sqlplus user/pass#hostname:1521/sidorservicename
