It is an install onto a Thinkpad W520 with Beowolf installed, it was working just fine, only a little bit of tearing on the screensaver. I installed some extra packages available. I was wanting to add emacs, but it came up with errors on that. I then noticed that Chimaera was available, and followed the instructions to upgrade, it seemed to go ok. Also dupeguru seemed not to be available, missing that capability.

Now cannot connect to either ethernet or wireless!
I also noticed a lot of repeated errors in   /var/log/syslog   of the form:
brltty[xxx]: unable to connect to polkit: g-io-error-quark (yyy) Error initialising authority: Could not connect: No such file or directory (1)

It has negotiated an ipv6 only address! it seems to be the only ipv6 on my hub, not sure if that is expected?

I am at a loss of where to look for the root cause of this. the thinkpad has an msata disk for booting, and an ssd for home, and another ssd for more storage, mounted in fstab as /data
df -h shows all mounts are present

How do I display the uuid's of the disks? currently using another laptop to troubleshoot the thinkpad, as it has no networking available.
