I want to create a cronjob to update and upgrade a pi once every day. My only issue is that at some points it asks permission to use or free up disk space. Is there an option to a command to continue with the coronjob?
What I am trying to run:
30 2 * * * sudo apt-get update && sudo apt-get upgrade
Actually you can use the root crontab. You can access it here:
sudo crontab -e
then add your program:
30 2 * * * apt-get update && apt-get upgrade
And it will be run with root permissions.

How to run a cron job inside a docker container?
(29 answers)
Closed 3 years ago.
I have a dockerfile image based on ubuntu. Iam trying to make a bash script run each day but the cron never runs. When the container is running, i check if cron is running and it is. the bash script works perfectly and the crontab command is well copied inside the container. i can't seem to find where the problem is coming from.
Here is the Dockerfile:
FROM snipe/snipe-it:latest
ENV TZ=America/Toronto
RUN apt-get update \
&& apt-get install awscli -y \
&& apt-get clean \
&& apt-get install cron -y \
&& rm -rf /var/lib/apt/lists/*
RUN mkdir /var/www/html/backups_scripts /var/www/html/config/scripts
COPY config/crontab.txt /var/www/html/backups_scripts
RUN /usr/bin/crontab /var/www/html/backups_scripts/crontab.txt
COPY config/scripts/backups.sh /var/www/html/config/scripts
CMD ["cron","-f"]
The last command CMD doesn't work. And as soon as i remove the cmd command i get this message when i check the cron task inside the container:
root#fcfb6052274a:/var/www/html# /etc/init.d/cron status
* cron is not running
Even if i start the cron process before the crontab, the crontab is still not launched
How can i tackle this problem ??? Thank you
You are running crontab in a RUN statement. But that only runs during image creation, not when you actually use the resulting image.
The below 3 lines are part of my shell script, but it is executing first line and copying file properly.
In-order execute this rpm file, i need to prompt to root user. Hence, 2nd step i wrote. But it is not executing, hence i'm not able to install the rpm file.
aws s3 cp s3://mybucket/oracle-instantclient12.2-basiclite.rpm /home/user1/
sudo su
yum -y install /home/user1/oracle-instantclient12.2-basiclite.rpm
So, any alternate solution to this (sudo su) or tell me how to prompt to root user in-order to install the mentioned rpm file.
Thanks
You could try using sudo -s or
sudo yum -y install /home/user1/oracle-instantclient12.2-basiclite-12.2.0.1.0-1.x86_64.rpm
The first option switches you to the root user, while the second allows you to run the command as root.
aws s3 cp s3://mybucket/oracle-instantclient12.2-basiclite.rpm /home/user1/ && sudo -i yum -y install /home/user1/oracle-instantclient12.2-basiclite.rpm
you'd have to add && (see this answer) in between the two commands and install with sudo yum:
aws s3 cp s3://mybucket/oracle-instantclient12.2-basiclite.rpm /home/user1/ && sudo yum -y install /home/user1/oracle-instantclient12.2-basiclite.rpm
sudo rpm -i /home/user1/oracle-instantclient12.2-basiclite.rpm should also work.
there is no other way to run two commands from a single command-line ...
are you sure the seconds half of the command-line even runs on the remote host? because I'd rather would expect it to be prefixed with send-command (in case running this from a local shell and not on the remote host). it is also not being indicated which Linux distribution you attempt to run the command against; adding the relevant RPM repository and then installing from there, might be the most reliable method of doing so.
I am a newbie with server handling and Linux. I am trying to install composer on my server so that i can host my Laravel project onto it as mentioned in the tutorial in Ultimate Guide: Deploy Laravel 5.3 App on LEMP Stack. I ssh into the server and after installation of composer when I run sudo mv composer.phar /usr/local/bin/composer I am getting a message in the terminal:
-bash: sudo: command not found
I desperately need some deliberate help
Sudo is probably not installed or not in your path
check to see if you are root in this case sudo is not needed unless you are trying to impersonate another user. just run your command without sudo mv composer.phar /usr/local/bin/composer
See if sudo is your path by running which sudo or echo $PATH. If sudo is not in your path, your path variable might be broken. You can try testing this by executing a common location for sudo /usr/bin/sudo or running locate sudo | grep bin to attempt to find its location.
If you know that sudo was installed, or your path looks broken, try fixing your path. Check your distribution's env file (/etc/environment in ubuntu) to make sure that it is formatted correctly (script commands are illegal in this file)
If you are not root and you want to run a command with root prvileges then you must install sudo. But if you don't have sudo and you are not root then you can't install it. In this case I recommend switching to the root user with su
If you do not have the root password and you own the machine, you can reset the root password with a tutorial such as https://askubuntu.com/questions/24006/how-do-i-reset-a-lost-administrative-password
After you manage to login as root install sudo with apt-get update; apt-get install sudosince you are using Ubuntu.
Verify the the name of your sudoers group with visudo and modify your sudoers file if you need to. https://www.digitalocean.com/community/tutorials/how-to-edit-the-sudoers-file-on-ubuntu-and-centos
if you have an existing sudoers group or you create one you can add yourself to the group. For example if your sudoers group is called sudo run usermod -aG sudo myuser. The sudoers group by default in Ubuntu based Linux is sudo. A sudoers group entry looks like this: %sudo ALL=(ALL:ALL) ALL
If you are trying to impersonate another user and cannot install sudo, you can still use su if it is installed and you have permission / password for the other user.
e.g. su someuser
As suggested in this post, you may have to install sudo in your server.
To do that, log in as root with the following command: su -. Then install sudo with your package manager (if you're in Ubuntu: apt-get install sudo).
Then add your user to the sudo group: usermod -aG sudo <username>.
Finally type exit to log out of the root account and go back to your user.
try to install your sudo using by first logging in as a root(su - ) and then try to install **apt-get or yum sudo **. Make sure your path variable is set so that you would be able to get binary.
which sudo
echo $PATH
As usual, every two weeks you get a new package with a new version of the application. which need to be installed on approximately 1,200 production servers.
What's your idea for the realization of this task? One can assume that your OS is Debian.?
what I did. I just created a simple script which inside contain the installation comand .
apt-get install chrome
But I dont know commands which can help me to install the application to manny other servers (1200) which I have acces to it through remotely . any suggestions..?
It would be a good idea to make a cron job.
$ crontab -e
And add a new line:
0 0 * * 0 root (apt-get update && apt-get upgrade -y) > /dev/null
This will run full a system update every Sunday midnight.
If you want to update only chrome:
0 0 * * 0 root (apt-get update && apt-get --only-upgrade install -y chrome) > /dev/null

I am trying run a specific version of couchdb on travis-ci I do this by following the offical apt-get instructions from couchdb
Part of the installation is a prompt for what to do with an old configuration file. See the following:
Installing new version of config file /etc/logrotate.d/couchdb ...
Configuration file `/etc/couchdb/local.ini'
==> Deleted (by you or by a script) since installation.
==> Package distributor has shipped an updated version.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : start a shell to examine the situation
The default action is to keep your current version.
*** local.ini (Y/I/N/O/D/Z) [default=N] ?
This causes travis-ci to hang and the build to fail.
Here is the travis-ci i have tried with and without the sudo rm and a handful of otherthings.
language: python
php:
- 2.7
install: "pip install -r requirements.txt"
before_install:
- "export DISPLAY=:99.0"
- "sh -e /etc/init.d/xvfb start"
- sudo apt-get install python-software-properties -y
- sudo add-apt-repository ppa:couchdb/stable -y
- sudo apt-get update -yq
- sudo apt-get remove couchdb couchdb-bin couchdb-common -yf
- sudo rm /etc/couchdb/local.ini
- sudo apt-get install -Vy couchdb
- sudo service couchdb start
before_script:
- curl -X PUT localhost:5984/njb_tests
script: python run-tests.py
You can see the different things i have tried by looking at my commit history:

Hello my Frind its quite easy
I believe this command will do the trick
The 100% Working way no excuse no mercy!!
sudo DEBIAN_FRONTEND=noninteractive apt-get -y -o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confnew" install couchdb
The Softer way probally working
export DEBIAN_FRONTEND=noninteractive
apt-get -o Dpkg::Options::="--force-confnew" install -y
The Right way
on shell or in code do
export DEBIAN_FRONTEND=noninteractive
then
sudo apt-get -q -y install couchdb
It will assume “yes” to everything (and do it quietly)
you need to watch Debconf is the name of the tool. That page should help you get going with everything you want to know. debconf man page
The expect script method
you get asked for package maintainer or a password you should set on apt-get do here a simple example from a server that asks to set password on apt-get install
To keep your existing password, leave this blank.
Password for SYSDBA:
then you run it with this script below to do the input
#!/usr/bin/expect
spawn dpkg-reconfigure firebird2.5-superclassic -freadline
expect "Enable Firebird server?"
send "Y\r"
expect "Password for SYSDBA:"
send "newpwd\r"
# done
expect eof
Working example for your case is
- /usr/bin/expect 'spawn sudo apt-get install -Vy couchdb \n expect "*** local.ini (Y/I/N/O/D/Z) [default=N] ?" \n send "Y\r"
