Bug#1075757: elogind’s conflict with libelogind0 precludes upgrade

[Benjamin Cama]

Package: elogind
Version: 246.10-1debian1
Severity: important

Dear Maintainer,

I tried to upgrade to the latest 255 version of elogind, but I do not 
understand the recent "Conflicts" addition with libelogind0: it renders 
it uninstallable together with latest libelogind0, and thus ask me to 
install libsystemd instead, which I do not want.

>From what I understand, dependency to libelogind0 has been dropped 
because it actually provides exactly the libsystemd ABI now, so elogind 
now depends on just libsystemd. But the addition of the "Conflicts" with 
libelogind0 makes its use as a libsystemd substitute impossible. What 
gives?

Maybe I have gotten something wrong, please tell me if so. Attached is 
my upgrade attempt (not a full/dist-upgrade) for just elogind *with* 
libelogind0 to nail the problem down; this is the output of:

  apt-get install elogind libsystemd0+ 

This issue first appeared when installing/upgrading *any* package, where 
apt wanted to install systemd on my system, because of some reverse 
dependency I suppose.

Thanks for your support of this nice alternative software BTW.

Regards.
