I confirmed on another machine that, immediately after "sudo port
selfupdate" from 2.9.3 to 2.10.1, I get

$ port outdated
sqlite error: attempt to write a readonly database (8) while executing query: CREATE INDEX registry.snapshot_file_id ON snapshot_files(id)

but if I do "sudo port outdated", I get the right thing:

$ sudo port outdated
The following installed ports are outdated:
bash 5.2.26_0 < 5.2.32_0
bind9 9.18.27_0 < 9.20.0_3
... etc etc ...

and then once I've done that, unprivileged "port outdated" works
again:

$ port outdated
The following installed ports are outdated:
bash 5.2.26_0 < 5.2.32_0
bind9 9.18.27_0 < 9.20.0_3
... yadda yadda ...

So there's definitely some behind-the-back updating going on there.
I'm not sure why the CI script should trigger that though. It
does do a couple of "port" calls without "sudo", but not in places
where the state should be only partially upgraded.
