Fedora DNF notes

<2023-04-08 Sat>

My personal notes that I use when trying to debug package issues on Fedora. Knowing what you are doing is always preferable to entering commands from StackExchange as root user.

1. The actual docs

2. General debugging

See a list of previous actions:

dnf history

See a list of user packages

dnf history userinstalled

Another approach:

sudo dnf repoquery --userinstalled

3. Get current Fedora release number

$ cat /etc/fedora-release

4. List available versions of a package

List versions of a package, which you could install right now:

dnf list --showduplicates $PACKAGE_NAME

Sometimes, new versions of a package are only available on a recent release. To check which versions are available on a different release, use:

dnf --releasever=29 --showduplicates list $PACKAGE_NAME

5. Upgrade to a different Fedora release

  • Upgrades are tested from the previous 2 releases. So, for example, if you are on 35 and want 39, you should go from 35 -> 37 -> 39.
  • Backups are a good idea before an upgrade
# Update DNF
sudo dnf --refresh upgrade
# Get the dnf system upgrade plugin
sudo dnf install dnf-plugin-system-upgrade --best
# Download the fedora 37 release
sudo dnf system-upgrade download --refresh --releasever=37
# Do upgrade and reboot
sudo dnf system-upgrade reboot

6. Get package that provides a command

Use dnf provides to look up a package associated with a given command.

dnf provides [command]

7. List files associated with a package

This is equivalent to finding where a package is installed.

dnf repoquery -l [Package]
