Firefox snap, Ubuntu, EPSON printer not available
So I had to repave my primary workstation to fix a problem with my ZFS configuration (my ashift setting was causing problems) and things are mostly back online, but I wasn’t able to print from firefox for some reason.
I think the problem was that I had installed firefox prior to adding the printer. Anyway, long story short, this command seemed to fix the problem for me:
# snap connect firefox:cups-control

How To List All Packages In A Repository On Ubuntu
There’s some good info about working with the Ubuntu APT repository over here: How To List All Packages In A Repository On Ubuntu, Debian Or Linux Mint [APT]. I’m finally starting to get my head around how the repositories actually work. This and this were helpful.
New KDE Plasma widgets
So I upgraded my Ubuntu from 20.04 to 22.04. That mostly went without problem but there are still a few gremlins to iron out. One change was some of the desktop widgets I was using in the previous version seem to have been replaced. I found the replacements easily enough. I particularly like the new CPU activity widget, it’s a much more sensible way to visualise 24 CPU cores than the previous widget which just gave one reading instead of 24.
python-subversion
I’m upgrading my Ubuntu from 20.04 to 22.04 and having a problem because the python-subversion package has been removed. I have asked a question about this over here, so hopefully I can get a resolution.

How to mount an Xbox formatted drive on Ubuntu
When I finally get a PCIe IDE adapter that works, this is gonna come in handy: How to mount an Xbox formatted drive on Ubuntu.
The IDE adapter that I have is this one, but it reports all disks as damaged (and they’re not). I think maybe it’s too new for the drives maybe? Speaking a newer version of the ATA protocol? I have no idea really.

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
