For first-time Linux users, I always recommend one of the main user friendly distributions - it is much easier to ask or look for help this way.

So, Fedora, Ubuntu or Opensuse.

Their installers all can live boot

Blog makes valid point, but why on earth there would be any current Linux distribution without usr merge?

EDIT: Especially when every major Linux distributions have already implemented usr merge long time ago.

I have seen this on HP laptop with WWAN device installed. Disabled device from Bios and problem went away.

Do you run docker container in privileged mode? https://phoenixnap.com/kb/docker-privileged

And do you run nano inside the container?

Docker container running in privileged mode has root permissions to host filesystem and devices (limited by said restrictions).

Yes I love Gnome workflow. Actually so much that if I am forced to use KDE for example, it feels really archaic and slow to use.
