I am fairly new to Linux, and am more familiar with use of rpm and yum, the latter of course resolves dependencies and installs the whole package. I have primarily used CentOs.
I am now trying to use an embedded Linux which is quite basic and only has rpm, no dnf or yum. I wanted to install yum, so I could have some flexibility with managing packages, but using rpm, all I get is a whole bunch of dependencies, some of which I try and resolve, like dnf and python-dnf, before it becomes a never ending list.
Is there an easier way to get yum installed on my system?
To do this is sample, straight (and boring) process.
First you find where is located package for your distribution and architecture and get the URL. For example for x86_64, CentOS 8 is (one of the mirrors):
http://centos.telecoms.bg/8/BaseOS/x86_64/os/Packages/yum-4.0.9.2-5.el8.noarch.rpm
Next you need to get dependencies of this package (based on what you have already installed) (to be run as root)
# rpm -q -R http://centos.telecoms.bg/8/AppStream/x86_64/os/Packages/anaconda-29.19.0.40-1.el8.x86_64.rpm
/bin/sh
/bin/sh
anaconda-core = 29.19.0.40-1.el8
anaconda-gui = 29.19.0.40-1.el8
anaconda-install-env-deps = 29.19.0.40-1.el8
anaconda-tui = 29.19.0.40-1.el8
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(FileDigests) <= 4.6.0-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
rpmlib(PayloadIsXz) <= 5.2-1
(in above example I use different package)
So you have already /bin/sh but need anaconda-core anaconda-gui anaconda-install-env-deps anaconda-tui rpmlib
Next you search for the URL of those packages in the repo. And check them one by one for dependencies. After getting all the URLs you create one long line to install all of them. Or install first the prerequisites and then the package.
rpm -i http://centos.telecoms.bg/8/AppStream/x86_64/os/Packages/anaconda-29.19.0.40-1.el8.x86_64.rpm \
http://centos.telecoms.bg/8/AppStream/x86_64/os/Packages/anaconda-core-29.19.0.40-1.el8.x86_64.rpm \
http://centos.telecoms.bg/8/AppStream/x86_64/os/Packages/anaconda-gui-29.19.0.40-1.el8.x86_64.rpm \
http://centos.telecoms.bg/8/AppStream/x86_64/os/Packages/anaconda-install-env-deps-29.19.0.40-1.el8.x86_64.rpm \

I followed following steps
make clean
./configure
sudo make install
shows -->
PostgreSQL installation complete.
but if typed psql
says -->
Command 'psql' not found, but can be installed with:
apt install postgresql-client-common
Please ask your administrator.
I dont want to install from apt-get install want to install everything from source code only
By default, PostgreSQL is installed in /usr/local/pgsql, so you would type /usr/local/pgsql/bin/psql for the command line client (but remember that you have to create and start a database cluster with initdb first`).
If you don't like that location, use the prefix option of configure:
./configure prefix=/dir/where/you/want/postgres
Usually, ./configure without options will install the product in /usr/local/ and this might not be in your PATH. Can you check psql is present in /usr/local/bin/? If so, you can type the full path to that or add /usr/local/bin/ to your PATH.

I've tried to install docker on my machine, following the instructions for Precise 12.04 found here.
When I try:
curl -sSL https://get.docker.com/ | sh
I get the result:
Either your platform is not easily detectable, is not supported by this
installer script (yet - PRs welcome! [hack/install.sh]), or does not yet have
a package for Docker. Please visit the following URL for more detailed
installation instructions:
https://docs.docker.com/en/latest/installation/
My kernel:
$ uname -r
3.13.0-61-generic
You can download the short installer script to take a look at why it is giving you this message:
curl -sSL https://get.docker.com/ >install-docker.sh
$EDITOR install-docker.sh
Doing that, I see several checks for lsb_release. Is your system missing that command? If so, see this to install it. Or maybe it’s not returning “ubuntu”. If you fix this, the docker installer script may work fine.
If that doesn’t work, you can hard-code a case for your OS (Mint?) in the ubuntu|debian case (line 243), like:
ubuntu|debian|linuxmint) # or maybe you’ll need here: *)
When done editing (or installing lsb_release), run the script to see if it will complete:
sudo ./install-docker.sh

I want to update the core packages of R on ubuntu 12.04. But every time R says that it has no permissions to write to the library. Other packages with do not come with the r-core installation through the terminal. sudo apt-get install r-base are installed in my personal library. I gave myself the owner permissions of every library folder and this does not work.
So am i able to make this library writtable and if so, how can i do it? Or is there a way to Run R as administrator/root.
I already tried a lot of options from the internet but could not find what i was looking for.
Many thanks in advance!
Yes, by default R packages get installed under /usr/lib, and you need superuser privileges to install more.
So you can either run R using sudo and run commands like install.packages() from there:
sudo R
or edit your ~/.Renviron as described in this post, e.g.
$ mkdir ~/R_libs
And add this line to ~/.Renviron:
R_LIBS="/home/your_username/R_libs"

My Perl code installed several (4) rpm files as root. the next install removes them (rpm -e) before installing a newer version. One does not remove, with rpm -e giving the error that it is not installed. However, later when the updated file is installed, the message is given that it is already installed.
Manual attempts to remove give the same results. My questions are how to force removal something from the rpm database, and why does this contradication exist (not installed from rpm -e and already installed from rpm -Uvh and rpm -ivh)?
Once installed, use the package name, not the package filename.
You should not need to remove a package before upgrading it. Doing so means that one or both of the packages are broken.
The reason it is not erased is likely because one of the scriptlets is failing. Do it manually and watch for errors. If it mentions a failed scriptlet, try erasing it with rpm -e --noscripts
rpm -e --force will not forcibly remove a package, rpm -e --nodeps will by stopping it to check for other dependencies.
It's possible your RPM database is in some way bent out of shape, you may wish to try an rpm --rebuilddb

How do I recreate an rpm which is already installed on a system on linux?
What version of RPM are you using? If you're using a newer one, I have a trick that might work for you.
Newer versions of RPM have a transaction safe rollback option; simply use the --repackage command, and it'll generate a package that includes all the idiosyncratic crap of the original install. Mind you, you'll have to actually DO something (e.g rpm -e --repackage rpm_goes_here which will ERASE the original, while making a package which you SHOULD be able to restore (after you've made a copy), but if you expect this to work perfectly, I have a BRIDGE you might want to buy), so it's a bit of a leap of faith if you don't have a full backup.
There is some configuration involved, and you need to test test test before you try this on something critical, but this may work.
Basically you will have to do the following:
1] Create a .spec file with all the headers [ http://www.rpm.org/max-rpm/s1-rpm-build-creating-spec-file.html ]
You will have to use the rpm -q --queryformat "" to get the header from the already installed rpm.
Eg. rpm -q --queryformat "Release: %{RELEASE}\n" installed_rpm
For getting the files to fill the %files Section use the rpm -ql command.
2] run rpmbuild -bb specfile to generate the rpm file.
Best way to recreate an RPM, is to do it from the source RPM. Great tutorial here.
The deltarpm package can do that:
A deltarpm contains the difference between an old and a new version of
a rpm, which makes it possible to recreate the new rpm from the
deltarpm and the old one. You don't have to have a copy of the old
rpm, deltarpms can also work with installed rpms.
