Description Alick Zhao 2019-04-22 03:05:50 UTC
Description of problem:

This bug is about the interplay between dnf and etckeeper (more specifically the etckeeper-dnf package). etckeeper has an option that, when enabled, aborts a 'dnf upgrade/install' operation when etckeeper detects there are uncommitted changes under /etc. This used to work fine, but now on Fedora 29, after etckeeper raises an error, dnf continues upgrading/installing packages, instead of aborting and letting the user 'etckeeper commit' first.

Version-Release number of selected component (if applicable):


How reproducible:

Steps to Reproduce:
1. In `/etc/etckeeper/etckeeper.conf`, uncomment `AVOID_COMMIT_BEFORE_INSTALL=1`
2. sudo dnf upgrade

Actual results:

$ sudo dnf upgrade
