DESCRIPTION:

Can’t update any apps from Jolla Store or Storeman any more.
Jolla Store only shows blank screen on My apps.

Running ssu with any option (e.g. ssu updaterepos) says:

WARNING: DBus call failed, falling back to libssu: Message recipient disconnected from message bus without replying

what(): /etc/zypp/repos.d/ssu_rinigus-flatpak_release.repo: Section [rinigus-flatpak]: Line 8 contains garbage (no ‘=’ or ‘:/?|,’ in key)

pkcon refresh stays endlessly on:

[root@xperia10 nemo]# pkcon refresh
Refreshing cache
Waiting in queue [ == ]

version --dup (forever) says:

[root@xperia10 nemo]# version --dup
REFRESHING CACHE AND DOWNLOADING PACKAGES
Waiting

but nothing happens

Updating to 3.4.0.24 is not possible.
Update is shown but doesn’t download.

Any idea what I can do to avoid resetting the phone?
