I can confirm this bug on my system as well. Upgraded from 18.04LTS to 20.04LTS. I have the same lsb_release -d and apt-cache policy gvfs output as well.
I worked around this issue by creating a symlink in /usr/lib/x86_64 -linux-gnu from libusbmuxd.so.6.0.0 to libusbmuxd.so.4 I don't know if this breaks anything, but this does seem to alleviate the slow launch of certain Gnome apps that seem to rely on gvfs, along with my slow login time that I was experiencing. Nautilus, gedit, file dialogs, screenshot, etc., that took ~20-30 seconds to load now load instantly, and I do not get org.gtk.vfs.AfcVolumeMonitor timeout errors I was seeing either. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gvfs in Ubuntu. https://bugs.launchpad.net/bugs/1877135 Title: Failed to start Virtual filesystem service - Apple File Conduit monitor [libusbmuxd.so.4 not found] Status in gvfs package in Ubuntu: New Bug description: After upgrading to Focal, /usr/libexec/gvfs-afc-volume-monitor fails with the message /usr/libexec/gvfs-afc-volume-monitor: error while loading shared libraries: libusbmuxd.so.4: cannot open shared object file: No such file or directory 1) lsb_release -rd: Description: Ubuntu 20.04 LTS Release: 20.04 2)apt-cache policy gvfs gvfs: Installed: 1.44.1-1ubuntu1 Candidate: 1.44.1-1ubuntu1 Version table: *** 1.44.1-1ubuntu1 500 500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages 100 /var/lib/dpkg/status 4) What happens: many applications (nautilus, gedit, etc) take ~30 sec to open. 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.

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.
