I am receiving numerous NM errors on startup, that I captured from
/var/log for one boot on Aug 16 18:10: I ask if the preserved ".files in
the home/user/ directories could be responsible for these errors?
In the captured "fail" list, NM is the main event per this thread
(nm_device_get_device_type: assertion 'NM_IS_DEVICE (self)' failed)
The problem got more pronounced after:
sudo add-apt-repository ppa:kubuntu-ppa/backports
sudo apt update
This was added after plasma repeatedly dropped the window ornaments.

I had made the unfortunate "upgrade" from kubuntu 14.04 with kxstudio
and decided to do a clean install to clean up the previous mess, leaving
kxstudio out (because kxstudio is skipping 16.04 in favor of 18.04):
I re-installed kubuntu 16.04,3 from disk downloaded 5 days ago
(1.562.112KB) preserving the /home/dad partition as well as a copy of
the fstab: (shows what was preserved during install on /dev/sd8

Also, each time I restart my desktop, NetworkManager generates a crash
report: cf. attached screenshots.
I have tried an Ubuntu VM with the same packages related to networking and
the exact same releases (same repositories), the crash never happens; the
difference appears to be only the type of network connection: WiFi for the
desktop vs Ethernet for the VM.
Any suggestion?
