Bug 1719729

Created attachment 1579818 [details]
full journal dump from the failed installation run

Description of problem:
Any Rawhide installation that has the Fedora modular repo enabled as one of the installation sources will fail due to libgit2 module related dpendency issues.

This will happen even if no module is marked for installation in the kickstart.



Version-Release number of selected component (if applicable):
libgit2:0.27:3120190407181414:f636be4b-0.x86_64 & libgit2:0.28

How reproducible:
always

Steps to Reproduce:
1. start an installation with the following kickstart:


url --url=https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/$basearch/os/
repo --name=modular --baseurl https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Modular/$basearch/os/

keyboard us
rootpw 12345
timezone America/New_York --nontp
zerombr
clearpart --all --initlabel
autopart

%packages
bash
%end


(Note that no modules are being requested for installation.)


Actual results:


The installation crashes at package installation time with the following error:

Expected results:

the installation will not be interrupted due to module dependency issue, especially given that no modules are requested to be installed.



Additional info:

This basically completely broke the Anaconda integration tests. As quite a few test (which are basically instrumented kickstart installations) test module installation, all the testing kickstarts have both the regular and modular Fedora Rawhide repositories as installation sources.

Due to this bug, all tests now fail, even though most don't attempt to enable or install any modules.

We could drop the modular repository from the test kickstarts, but that would make all the tests that actually enable and/or install modules fail.

Also one would generally assume adding the modular repository should be a safe operation.
