Hello all,

In my last upgrade of packages, lib32-libcap gave me this error: 
warning: ignoring package systemd-246.6-1
warning: cannot resolve "systemd", a dependency of "lib32-systemd"
warning: cannot resolve "lib32-systemd", a dependency of "lib32-dbus"

On closer inspection, I've noticed some differences between the lib32-dbus provided by multilib and the one provided by obmultilib:

They are at different versions, and the package from multilib also provides libdbus-1.so=3-32 (obmultilib's package does not).
I believe that's the reason to lib32-libcap be pulling lib32-dbus from multilib instead of obmultilib.
For now, I'm ignoring lib32-libcap to be able to update and everything seems to be working as usual.
However, I would like to know if the lib32-dbus provided by obmultilib can be updated to also provide libdbus-1.so=3-32.
Or is there a technical reason to not provide it? Maybe it's just because it's in a previous version?
I have no knowledge about the intricacies of dbus, so I'm just letting you all know there is a problem with it.
no reason at all except that i didn't take a look on obmultilib from a while.

So, sync and update :)

Thank you for the update! However, the problem is still there. I compared the PKGBUILDs, and it seems to be simple to solve it.
obmultilib's PKGBUILD only lists 'lib32-libdbus' in provides. Arch's PKGBUILD also lists 'libdbus-1.so' in provides.
I was a little confused by this, since both, dbus and lib32-dbus, provide 'libdbus-1.so'. I would expect the multilib version to provide 'lib32-libdbus-1.so', but that is not the case.
Either way, I check the files and, indeed, there are '/usr/lib32/libdbus-1.so*' files that are provided by lib32-libdbus.
Therefore, I believe it's safe to add 'libdbus-1.so' in the provides list of lib32-libdbus. Doing that should solve the issue.

For reference, the error (notice it's requiring libdbus-1.so):
