I can also confirm that symlinking libusbmuxd.so.6.0.0 to libusbmuxd.so.4 appears to allow the upower service to start as well. systemctl now shows the service started successfully and is running, and I am able to see power / battery status in Gnome again.

When starting those via the command line, after after those 30 secs the app opens with the following printed to the terminal: "Error creating proxy: Error calling StartServiceByName for org.gtk.vfs.AfcVolumeMonitor: Timeout was reached (g-io-error-quark, 24)" 3) What you expected to happen: applications to open without delay ============= Additional info: After calling 'journalctl -b', several instances like dbus-daemon[2031]: [session uid=1000 pid=2031] Activating via systemd: service name='org.gtk.vfs.AfcVolumeMonitor' unit='gvfs-afc-volume-monitor.service' requested by ':1.25' (uid=1000 pid=2135 comm="/usr/bin/gnome-shell " label="unconfined") systemd[1964]: Starting Virtual filesystem service - Apple File Conduit monitor... gvfs-afc-volume-monitor[2279]: /usr/libexec/gvfs-afc-volume-monitor: error while loading shared libraries: libusbmuxd.so.4: cannot open shared object file: No such file or directory systemd[1964]: gvfs-afc-volume-monitor.service: Main process exited, code=exited, status=127/n/a systemd[1964]: gvfs-afc-volume-monitor.service: Failed with result 'exit-code'. systemd[1964]: Failed to start Virtual filesystem service - Apple File Conduit monitor. Also upowerd is affected: /usr/lib/upower/upowerd: error while loading shared libraries: libusbmuxd.so.4: cannot open shared object file: No such file or directory upower.service: Main process exited, code=exited, status=127/n/a upower.service: Failed with result 'exit-code'. Failed to start Daemon for power management. The package libusbmuxd6 is installed (and /usr/lib/x86_64-linux- gnu/libusbmuxd.so.6 is present), but when trying "sudo apt install libusbmuxd4", I get the error "E: Unable to locate package libusbmuxd4". It would appear to me that some dependencies *somewhere* are not properly updated (to libusbmuxd6 from libusbmuxd4). Unfortunately, the huge timeout significantly affects usability of the computer, as one has to wait a lot to perform many tasks (opening nautilus, gedit); one has to wait also before login screen appears after a reboot.
