Description Marja Van Waes 2017-10-10 10:15:19 CEST 
When updating my system, DNF tries this:

Installing dependencies:
 lib64qtsoap2       x86_64       2.7-10.mga7        cauldron-x86_64        74 k
     replacing  qtsoap.x86_64 2.7-9.mga6
 libqtsoap2         i586         2.7-10.mga7        cauldron-i586          77 k
     replacing  qtsoap.x86_64 2.7-9.mga6

and fails

It would be nice if dnf would handle this like urpmi does:

[root@localhost marja]# LC_ALL=C urpmi --auto-update --test
medium "Core Release (RedHD21)" is up-to-date
medium "Nonfree Release (RedHD211)" is up-to-date
medium "Core 32bit Release (RedHD231)" is up-to-date
medium "Nonfree 32bit Release (RedHD236)" is up-to-date
To satisfy dependencies, the following package is going to be installed:
(test only, installation will not be actually done)
  Package                        Version      Release       Arch
(medium "Core Release (RedHD21)")
  lib64qtsoap2                   2.7          10.mga7       x86_64
3.9KB of disk space will be freed.
73KB of packages will be retrieved.
Proceed with the installation of one package? (Y/n) y

dnf debugdata can be found, here:

<only for Neal>retrying with "XZ_OPT=-e9 tar cJf debugdata.tar.xz debugdata" after first gunzipping the files, gave a much better result: 6.7M instead of 12M ... pity that's still to large for our Bugzilla</only for Neal>

Two packages obsolete qtsoap but named differently. In that case, libsolv tries to install all of them. I would report this bug to https://github.com/openSUSE/libsolv and try to get some hint from @mls.
Comment 2 Neal Gompa 2017-10-10 11:34:12 CEST 
@Igor, my suspicion is that this has to do with the fact that libsolv and DNF don't recognize this as multiarch versions of the same package, since they are differently named.

Unlike Fedora, where it's libfoo.arch, Mageia does %{_lib}foo.arch, which means the package name differs between 32-bit and 64-bit architectures.
Comment 3 Neal Gompa 2017-10-25 06:38:00 CEST 
This is a libsolv issue, not a dnf one.

Comment 4 Neal Gompa 2017-10-25 15:05:35 CEST 
After asking Michael Schroeder to look at this bug, he made a fix in libsolv for it: https://github.com/openSUSE/libsolv/commit/804a86ca950f7b7600db58f6ccf3fae4e374a9e3

testsolv indicates that the behavior is fixed, so libsolv-0.6.30 with the patch backported has been submitted to Cauldron.

This issue also afflicts Mageia 6, so if this is determined to be good, I'll backport libsolv-0.6.30 with fixes to Mageia 6 along with updated DNF stack.

Did you backport right patch then? ;)

I think so!
