systemd-binfmt.service masked

[brasswood]

I noticed today that apt upgrade gave me the message Failed to restart systemd-binfmt.service: Unit systemd-binfmt.service is masked.

$ systemctl status systemd-binfmt.service

Odd that would happen in a package upgrade.

Have you tried the following?

sudo systemctl unmask systemd-binfmt.service
sudo systemctl start systemd-binfmt.service
systemctl status systemd-binfmt.service

and optionally:

sudo systemctl enable systemd-binfmt.service

if you want to run on each start.

@sirredbeard Odd that I would get that error message from a package upgrade, or odd that a package upgrade would mask the service? I'm not actually sure what caused the service to get masked, though I'm fairly sure I didn't manually do it.

The link was made on September 29, 2023 so I'm looking through logs from that date to see if anything happened.

[brasswood]

Strangely, the link was made 11 seconds before journald logs begin. Could this have happened if I upgraded from WSL 1 to WSL 2 at that time?

I suppose I will unmask the service and hope that nothing breaks.
