Description Miro Hrončok 2023-07-11 08:47:47 UTC

It's quite easy to remove dnf5 with dnf5. A Fedora 39+ system then has no package manager. Please ensure dnf5 is marked as protected.

Reproducible: Always

Steps to Reproduce:
1.# dnf remove dnf5
Actual Results:  
Transaction Summary:
 Removing:         32 packages
...
[ 3/33] Erasing dnf5-0:5.0.15-3.fc39.x86_64
...

Expected Results:  
Failed to resolve the transaction:
Problem: The operation would result in removing the following protected packages: dnf5


# dnf
bash: dnf: command not found
# yum
bash: yum: command not found

I guess we need to add the "dnf5" package here: https://github.com/rpm-software-management/dnf5/blob/5.0.15/libdnf5/conf/config_main.cpp#L296. The "dnf" is not working now as it is only an alias.

just a +1 here. I noticed the dnf removal issue for the first time today. I've been running rawhide for over a month IIRC.

I usually run: sudo dnf5 -y update --allowerasing --best, and it has worked without issues until today.


I was able to get things back on track with `rpm -i $DOWNLOADED_DNF_RPM_FILE`

Comment 3 Fedora Release Engineering 2023-08-16 08:12:13 UTC

This bug appears to have been reported against 'rawhide' during the Fedora Linux 39 development cycle.
Changing version to 39.
