authselect-1.1-6.fc32 seems unable to restore the default configuration

[fcami]

I have two backups:

# authselect backup-list
2020-02-07-22-33-43.M8fOg6 (created at Fri 07 Feb 2020 11:33:43 PM CET)
2020-02-07-22-38-28.Uukas2 (created at Fri 07 Feb 2020 11:38:28 PM CET)

the first one is a backup of the default configuration done in rawhide (authselect-1.1-6.fc32.x86_64).
Trying to restore it fails:

[error] Unable to restore [2020-02-07-22-33-43.M8fOg6] [2]: No such file or directory
Unable to restore backup [2020-02-07-22-33-43.M8fOg6] [2]: No such file or directory

Using strace, we see it successively choke on:

openat(AT_FDCWD, "/var/lib/authselect/backups/2020-02-07-22-33-43.M8fOg6/dconf-db", O_RDONLY) = -1 ENOENT (No such file or directory)

and:

openat(AT_FDCWD, "/var/lib/authselect/backups/2020-02-07-22-33-43.M8fOg6/dconf-locks", O_RDONLY) = -1 ENOENT (No such file or directory)

Simply creating empty files:

# touch /var/lib/authselect/backups/2020-02-07-22-33-43.M8fOg6/dconf-db
# touch /var/lib/authselect/backups/2020-02-07-22-33-43.M8fOg6/dconf-locks

makes it work:

# authselect backup-restore 2020-02-07-22-33-43.M8fOg6

and the backuped nsswitch is now identical to the original:

config]# md5sum nsswitch.conf /etc/nsswitch.conf
5cc1a8341dbebe35bab636912a0e4b47  nsswitch.conf
5cc1a8341dbebe35bab636912a0e4b47  /etc/nsswitch.conf

from the FreeIPA bug report

If you need any more information please let me know.

Hi @pbrezina the build at https://koji.fedoraproject.org/koji/taskinfo?taskID=41467298 fixes the issue on a non-FreeIPA rawhide reproducer at least. Thank you very much!
