Bug#1003664: fwupd: Too loose dependency on libfwupdN

[Guillem Jover <guillem@debian.org>]

Package: fwupd
Version: 1.5.7-5
Severity: serious

Hi!

This package seems to use a too loose dependency on at least
libfwupdN, but I suspect the same applies to libfwupdpluginM (or even
libfwupdN from libfwupdpluginM).

These are encoded as >=, which causes them to be upgradable on new
upstream releases, and do break partial upgrades. Right now I've got
fwupd held due to the signed version not being yet available, and
libfwupdplugin1 is not upgraded as that bumped its SONAME, but libfwupd2
did, and now the daemon is segfaulting. This is not the first time
this has happened, but I guess I forgot to file the other time, which
means this seems to be consistent behavior as with requiring exact
versions of the library:

  fwupd[108906]: 21:12:16:0092 GLib-GIO             g_file_new_for_path: assertion 'path != NULL' failed
  fwupd[108906]: 21:12:16:0092 GLib-GIO             g_file_query_file_type: assertion 'G_IS_FILE(file)' failed
  fwupd[108906]: 21:12:16:0092 GLib-GIO             g_file_monitor_file: assertion 'G_IS_FILE (file)' failed
  kernel: fwupd[108906]: segfault at 8 ip 0000559242c78109 sp 00007ffe4df24910 error 4 in fwupd[559242c73000+26000]
  kernel: Code: ff 85 c0 0f 85 97 02 00 00 48 8b 7c 24 30 e8 5e d5 ff ff e9 67 01 00 00 48 8b 44 24 28 48 8d 3d dc 14 02 00 41 be 01 00 00 00 <48> 8b 70 08 31 c0 e8 4c f4 ff ff 4d 85 e4 74 08 4c 89 e7 e8 5f db

So it looks like all the intra library dependencies should be changed
to «libfwup.* (= <version>)».

Thanks,
