I would like to delete the default libertine container. I tried via terminal, then "Libertine.py:125: ERROR: _delete_rootfs(): [Errno 13] Permission denied: 'dev'" appears. I tried this also via adb shell on pc - the same... Via swipe right in system settings (Libertine) and tap on red trash symbol nothing happens. No spinning wheel...
I'm on bq m10 hd xenial 16.04 stable.
Weird. Maybe try to reboot, then try again to delete first thing after the reboot.
Ps: your question would be better served in it's own thread. It's a different problem.
