When dnf fails.

Questions to David Rotermund

Let us assume the dnf update inbetween. You lost the remote connection to the computer where the update was running or systemd oom killed the dnf task.

Now you are stuck in dnf limbo. How to get out of it with less effort as possible?

Try 0

If you can do this without an error then you are on a good way:

dnf -y remove --duplicates 

Try 1

Well, if try 0 resulted in conflicts, we can try to solve them semi-autotamic:

dnf -y remove --duplicates 2> error.log
cat error.log | awk -F 'from install of|conflicts with file from package' '{print $2}' | sort -u | awk 'NF' | sed s/"^ "/"dnf -y reinstall "/g | sh
dnf -y remove --duplicates 2> error.log

Try 2

We end up here if errors after try 1 still remained:

cat error.log | awk -F 'from install of|conflicts with file from package' '{print $2}' | sort -u | awk 'NF'
