Description Carl George 2018-02-14 22:04:27 UTC 
Description of problem:
Installing mariadb-server in a Rawhide container resolves some dependencies to community-mysql, which has conflicting files with mariadb-server.

Version-Release number of selected component (if applicable):
mariadb-server-3:10.2.12-5.fc28
community-mysql-5.7.21-1.fc28

Steps to Reproduce:
1. docker run -it --rm registry.fedoraproject.org/fedora:28
2. dnf install mariadb-server

Actual results:
Fedora - Rawhide - Developmental packages for  899 kB/s |  60 MB     01:08

Error: Transaction check error:

Error Summary
-------------

Expected results:
successful installation

Additional info:
Installing mariadb at the same time as mariadb-server is enough to complete the transaction successfully.  That makes me think the root issue is related to mariadb-server requiring mysql(x86-64) instead of mariadb directly.
Comment 1 Terje Røsten 2018-02-15 20:43:24 UTC 
my_print_defaults should moved to community-mysql-server I think.

Other thing is that server should not require mysql(x86-64) at all,
there is no need for client for server to start.
 
(in pre systemd days mysqladmin was used in initscript to check server was up,
however there is no such need any longer).
Comment 2 Michal Schorm 2018-02-19 01:05:16 UTC 
Two separate issues:

1)
I try to make mariadb and mysql installable together in a matrix of ways.
I'll move the files to the correct location, so they won't confict

2)
Why the docker DNF like coomunity-mysql client more, I can't tell for now.
Comment 3 Carl George 2018-02-19 22:32:31 UTC 
Yeah it would be nice if dnf had additional flags to show more insight into resolution logic.  See also: https://bugzilla.redhat.com/show_bug.cgi?id=1148627
Comment 4 Fedora End Of Life 2018-02-20 15:24:48 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle.
Changing version to '28'.
Comment 5 Michal Schorm 2018-03-06 11:36:18 UTC 
The first issue was solved by an update I made for community-mysql package, fixing confilcting files.

The second issue is still a mystery, however it is not a severe issue anymore.



Leaving this bugzilla open to find out.
Comment 6 Michal Schorm 2018-03-06 11:46:57 UTC 
In the fresh docker container, if you run first this update:
  dnf update -y --nogpgcheck gdbm openssl-libs

Then mariadb-server will resolve correctly
  dnf install --assumeno mariadb-server
Comment 7 Jaroslav Mracek 2018-03-23 12:26:22 UTC 
I think that the file conflict should be solved on packaging level. If there are two packages that provides same file, but checksum of those files is different (always if they are from different srpm), there should be a conflict in spec. Like: "Conflicts: community-mysql" (in mariadb-server).

I believe that solution in Comment 6 is based on new weak deps in updated packages, but this is an only guess.
Comment 8 Michal Schorm 2018-09-05 06:46:19 UTC 
Should be fixed now.

Can you confirm it for me please?
Comment 9 Carl George 2018-09-05 13:39:03 UTC 
Yes, it works now.  Thanks!
Comment 10 Michal Schorm 2018-09-05 13:59:06 UTC 
No problem, enjoy :)

Unfortunatelly it took so long. Sorry for that.

The issue - i believe - was hidden in the exact version of OpenSSL both databases was built with. DNF then prefered a combination, that required less changes in the system (e.g. not updating OpenSSL package).
With combination of weak dependencies it resolved in such a way.

That's why update of the system solved the issue (the OpenSSL package was updated too)

And that's why it wasn't reproducible in base Fedora, where the OpenSSL package was already updated. The container image holds an old version.
