Reinstall Linux on the Dell laptop

Goal is to test the Linux Mint upgrade (from 20.x to 21.xx).  But I first tried installing Fedora.  However the out-of-the-box install couldn't cope with the Broadcom wi-fi interface so I quickly gave up on that one.  I installed from the same Linux Mint as what I have used on the Medion laptop (I think 20.04).  Worked like a charm but I had to install the firmware-b43-installer (and required b43-fwcutter) to support said wi-fi interface.

Then added darktable (from the apt repo: 3.0 only so I got 3.4.0 from Software Manager instead).  Also added rapid-photo-downloader and all its prerequisites.

So:

sudo apt install firmware-b43-installer

sudo apt install rapid-photo-downloader

sudo apt install autofs

sudo vi /etc/auto.master

sudo service autofs restart

Also, renamed the host to "run12l" (the prior hostname when running under Ubuntu):

sudo vi /etc/hostname

sudo vi /etc/hosts

Then also reinstalled the urbackup client (via the server's web interface "download client" link, not from the internet -- because this allows the client certificate from the old client to work with the server, so we can restore old files that were backed up prior to the OS change).  By the way to enable restore with the web interface, it is necessary -- after install -- to edit /etc/default/urbackupclient and set option 

RESTORE="server-confirms"

Please note that the quotes are required in that line.  Then reboot or use

sudo service urbackupclientbackend restart
