Hi list,

For close to two weeks now, I think, I've been seeing my near daily

apt update
apt upgrade

routine on a daedalus machine holding back the upgrade of libelogind0.
That looks like this

  root@basecamp:~# apt-mark showhold
  root@basecamp:~# apt update

  The following packages have been kept back:
    libelogind0
  0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

So I figured I'd take a look at what a full-upgrade would do instead

  root@basecamp:~# apt full-upgrade --assume-no

  The following package was automatically installed and is no longer required:
    libelogind0
  Use 'apt autoremove' to remove it.
  The following NEW packages will be installed:
    libsystemd0
  The following packages will be upgraded:
    libelogind0
  1 upgraded, 1 newly installed, 0 to remove and 0 not upgraded.

Hmm, installing libsystemd0? No thanks, because

  root@basecamp:~# apt-cache madison libelogind0 libsystemd0
  libelogind0 |   246.10-4 | http://deb.devuan.org/merged daedalus/main amd64 Packages
  libsystemd0 |    250.4-1 | http://deb.devuan.org/merged daedalus/main amd64 Packages

indicates that libsystemd0 is straight from the Debian systemd
Maintainers.

Next, I thought I'd take a look at installing that particular version of
libelogind0

  root@basecamp:~# apt install libelogind0=246.10-4 --assume-no

  Abort.

Huh? How come libelogind0 is so hell-bent on installing libsystemd0?
Looking at the libelogind0 dependencies, I see

root@basecamp:~# apt show libelogind0 2>/dev/null | grep Depends:
Depends: libc6 (>= 2.33), libcap2 (>= 1:2.10)

and checking those, I get

root@basecamp:~# apt list --installed 2>/dev/null | egrep '(libc6|libcap2)'
libc6/testing,now 2.33-7 amd64 [installed,automatic]
libcap2-bin/testing,now 1:2.44-1 amd64 [installed,automatic]
libcap2/testing,now 1:2.44-1 amd64 [installed,automatic]

which satisfies the requirements.

Ah! Looking at the currently installed libelogind0=246.10-3, I see it
Provides: libsystemd0 whereas libelogind0=246.10-4 no longer does.

Any reason that was dropped?

# I'm aware of some changes having been made to get packages with a
# Build-Depends: on libsystemd0 to build from source again.

Guess I'll just sit this one out, maybe even put libelogind0 on hold for
a while, until things are sorted out.

Hope this helps,
