From the version number I gather you're having this issue on Debian 10
Buster.

Seeing i386 packages: Is this a multi-arch system, i.e. does it use
i386 and amd64 packages or just i386 packages?

I only have Buster amd64 here, so might not see exactly the same
package relations.

Looks like it won't update evince-common for some reason.

Do you happen to have apt-listbugs installed? It might pin packages to
older versions due to bugs so they aren't upgraded.

I suspect another issue here as 3.30 <= 3.30.2-3+deb10 < 3.31 is true,
too, and also worked for me on Buster (but amd64).

Can you please run "aptitude-create-state-bundle evince.tbz2" on that
system after having exited aptitude with "q" (so that the current
state is saved).

It will put all files relevant to reproduce this issue (package lists,
package states, aptitude settings, etc.) into a bzip2 compressed tar
archive given as parameter. It might become something between 20 and
200 MB, so it's usually not suitable for transfering by e-mail.
Uploading it somewhere and telling us (or just me if you don't want
the link published in a public list archive) the link to it.

We might have some common acquaintances... :-)
