    Default Snapper error "Cannot call has_iface? if not intrspected" nor continue `zypper upgrade`

    Seeking help on
    (1) snapper error
    (2) some free space appears missing I think related to (1)

    I was running a `zypper update` to switch the box from 42.2 to 42.3 (yeah slow I know) which failed due to no disk space. My usual fix is to load snapper & delete old snapshots & continue...


    Opening snapper from GUI asks for root password then nothing. From terminal I get the snapper draw on screen then the following error before it too closes


    "Error
    Querying snapper configurations failed
    Cannot call has_iface? if not introspected"


    df -h shows

    I logged out & back in, even rebooted, and the system is reporting 42.3 but I know it didn't complete upgrade.


    A `zypper upgrade` reveals
    1339 packages to upgrade, 59 new, 8 to remove, 2 to change arch.
    Overall download size: 1.86 GiB. Already cached: 0 B. After the operation, additional 358.5 MiB will be used.
    (i forget the % it completed; my system is bloated with many DEsktops; all valuable data is backed up)

    i have since `snap delete 2` but didn't get any extra disk space.
    I have rebooted using 42.2 install-thumb-drive and `btrfs check /dev/sda8` and nothing [unusual] shown
    I have run `zypper clean -a` & a few other hail-mary's to no avail.
    I had ~4gb free space in / for 42.2 -> 42.3 jump

    My system performs normally & like an opensuse should (clean & reliable)

    Any thoughts on snapper error, or my space issue greatly appreciated.

    Third (re)boot (plus cold boots) and I logged into text-terminal (ctrl+alt+f4) and for some reason this time `df -h` showed 4.1gb [Yeah my space is back] available in /, so I let `zypper update` continue 42.3 upgrade and it completed.

    I've done something and Snapper no longer shows in Yast2 (terminal or YaST (gui); one was modification to /etc/sysconfig/yast2 [USE_SNAPPER="no"] which sounds like the cause; the second I've forgotten (max number of snapshots stored)

    Anyway - problem fixed itself.
