Doc Text:
.The installer no longer installs earlier versions of packages Previously, the installer did not correctly load the DNF configuration file during the installation process. As a consequence, the installer sometimes installed earlier versions of select packages in the RPM transaction. This bug has been fixed, and only the latest versions of packages are now installed from the installation repositories. In cases where it is impossible to install the latest versions of the packages, the installation fails as expected.

Description Oliver Falk 2020-11-19 12:12:54 UTC
Description of problem:
Given a kickstart file, if you add deprecated packages (eg. langtable-data) to the packages to be installed, the DNF transaction will end up trying to downgrade packages. However, since older packages are potentially not available in the repository, the transaction error message the user is presented with may look like this (random example):

    14:06:57,611 CRT dnf: Error opening file for checksum: /run/install/LocalRHEL-AppStream.nfs/Packages/w/webkit2gtk3-jsc-2.24.4-2.el8_1.x86_64.rpm
    14:06:57,612 CRT dnf: Package "webkit2gtk3-jsc-2.24.4-2.el8_1.x86_64" from local repository "LocalRHEL-AppStream" has incorrect checksum
    14:06:57,682 CRT dnf: Error opening file for checksum: /run/install/LocalRHEL-AppStream.nfs/Packages/l/libreoffice-core-
    14:06:57,682 CRT dnf: Package "libreoffice-core-1:" from local repository "LocalRHEL-AppStream" has incorrect checksum
    14:06:57,684 CRT dnf: Error opening file for checksum: /run/install/LocalRHEL-AppStream.nfs/Packages/l/libreoffice-draw-

This looks like there is a problem with the checksum, but the real issue is the file/package isn't available since the dnf transaction tried to downgrade to package not available.

Version-Release number of selected component (if applicable): 8.x

How reproducible: Always

Steps to Reproduce:
1. Use reposync to fetch the relevant RHEL 8(.3) repositories
2. Add any package that has been deprecated from 8.2 to 8.3 to your kickstart file
3. Use this as installation source during a RHEL 8.3 install

Actual results:
Error message is misleadning and it's anyway questionable if Anaconda should allow downgrades during the DNF transaction - but there might be reasons.

Expected results:
Better error message and/or downgrading during the DNF transaction isn't allowed unless explicitly asked for (kickstart config option?)

Additional info:
Linking customer case.

Comment 3 Jiri Konecny 2020-11-19 13:47:22 UTC
Hi, thank you a lot for investigation. If the same issue is happening also for the direct `yum` calls then it's not a specific to Anaconda but rather problem DNF behavior.

Switching component to DNF.

Comment 4 Oliver Falk 2020-11-19 15:39:34 UTC
With direct yum calls, it's obvious. The point here is that Anaconda should catch this somehow and provide the user with a more meaningful error message.

And my additional point was that we should potentially think about if Anaconda should run DNF in a away that would prevent downgrading at all, since this will in almost all cases lead to a failure, as usually only the latest packages are available in the repositories.


Comment 5 Daniel Mach 2020-11-23 12:11:13 UTC
Reassigning back to anaconda based on the previous comment.

Comment 6 Pavla Kratochvilova 2020-11-23 15:21:02 UTC
After additional discussion, I am reassigning this back to dnf, because the error message should probably be improved already in dnf.

As for the question whether Anaconda should run DNF in a way that would prevent downgrades, I don't think that's what's happening, because Anaconda just installs all the packages (it doesn't do any upgrades/downgrades). I'd say the problem is more likely in repositories (having inconsistent repodata).

Comment 14 Jiri Konecny 2022-02-11 14:29:02 UTC
Based on the comment 13, I'm removing the FutureFeature because this seems like inconsistency in the Anaconda configuration. We should investigate the reasoning for not loading the best= option.
