Snapper is failing to create snapshots about snapper

[aschnell]

One thing is AFAIS that you hit bug #856:

WAR libsnapper(3328) Client.cc(check_permission):436 - THROW: no permissions

But that should not cause further problems.

What really looks strange is this:

[ALPM-SCRIPTLET] Invalid snapshot '--type'.

As if a program passes --type instead of a snapshot number.

I am using snap-pac. It was working as expected before I restored. There is also pre-upgrade snapshot [ALPM-SCRIPTLET] Creating snapshot failed.
One interesting thing happening as you can see in ls -la /.snapshot

drwxr-x---+ 1 root root  24 Apr 19 18:34 .
drwxr-xr-x  1 root root 158 Apr 18 18:35 ..
drwxr-xr-x  1 root root  32 Apr 17 23:55 825
drwxr-xr-x  1 root root  32 Apr 19 00:45 826
drwxr-xr-x  1 root root  32 Apr 19 00:45 827
drwxr-xr-x  1 root root  32 Apr 19 00:48 828

But in snapper.log I can still see MIL libsnapper(3038) Snapshot.cc(read):344 - found 5 snapshots

After upgrading to latest version, everything is working as expected. Here is the latest snapper.log.

Unclear cause but is fixed now.
