Description jcastran 2023-02-21 21:06:31 UTC

Description of problem:
When the .i686 arch of a multilib package is installed first, you can not undo the later transaction which installed the .x86_64 variant.


Version-Release number of selected component (if applicable):
[root@r8 repo]# rpm -q dnf libsolv
dnf-4.7.0-11.el8.noarch
libsolv-0.7.20-4.el8_7.x86_64

How reproducible:
Everytime

Steps to Reproduce:
1. Do not have libpq installed
2. # yum -y install libpq.i686
3. # yum -y install libpq
4. # yum history undo last      ##This should undo the libpq.x86_64 transaction

Actual results:
Error:
 Problem: problem with installed package libpq-13.5-1.el8.i686
  - libpq-13.5-1.el8.i686 has inferior architecture
  - conflicting requests
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)


Expected results:
Since we could install libpq.i686 without .x86_64 in the first place, theres no reason we can't undo the transaction with .x86_64 in it.

Note: I needed to change step 3 to:
3. # yum -y install libpq.x86_64
to reproduce on Fedora 37.

Comment 4 Jaroslav Mracek 2023-03-21 13:51:52 UTC

I've created an issue on libsolv (https://github.com/openSUSE/libsolv/issues/525). The issue contains reproducer using libsolv testcase.
