Maybe this is causing problems for unrelated manuals? I don't know. I don't
have Chrome installed, and I don't get that warning.

I'm surprised devhelp gets EPERM reading files in /usr/share/doc that I
would have expected to be world-readable. Are the permissions on
any element of that that path more restrictive?

Or is this maybe an AppArmor proplem? (Please check the systemd journal.)

Those warnings can be ignored, I get those too (and devhelp still works).
