# Fedora 31 Upgrade

Finished upgrading all of the computers in my home from [Fedora][0] 30
to Fedora 31 over the long weekend. It was pretty uneventful!
My own laptop went smoothly, though slowly, because it has a mechanical
hard drive. All of the packaged software upgraded correctly and with no
intervention, including the stuff installed from [RPMFusion][1]. I had
quite a bit of self-compiled stuff, mostly relating to [sway][2], and
some of that had to be re-linked. Also, PAM (authentication modules)
stopped seeing swaylock's PAM config in /usr/local/etc, so I had to copy
it into /etc/. I used Gnome for a while after the upgrade, not because
sway wasn't working (I had it working again the same day), but because I
wanted to have a different feel for a little while.
My eldest child's laptop went without a hitch; nothing unusual installed
on that one.
For my home desktop/server, there are usually some issues. Generally
postgresql needs some manual attention, and everything that depends on
it will need some work. That wasn't the case this time. All of the usual
tiny issues were absent, and everything was completely smooth...except
for one thing, which was a doozy.
For search engines: docker does not work on Fedora 31.
I had one service running under docker, and it was completely broken.
Fedora doesn't package docker anymore, and the free software fork they
do package, moby-engine, doesn't work without changing the boot options
on your kernel: it needs cgroupsv1, and the Linux kernel shipping in
Fedora now defaults to cgroupsv2. I was prepared to install moby-engine
and go through the steps needed to restore cgroupsv1, but I preferred to
do things the right way for moving forward.
That was to install [podman][3]. Podman is a container engine with a
command-line that is backwards-compatible with docker, and it is
packaged by Fedora. All I needed to do to get it running was to install
it and edit the systemd unit file I had been using to start the service.
All in all it was a pretty easy upgrade. If the one service I had
running on docker had been more critical, though, that one catch would
have ruined my day.
