Fresh testing VM.


Plain Text doc just containing "Test".


Exported to PDF.


Opening just works. Both in LO and by command line.


Did you do any special config? Something apparmor-related? Some specific
TMPDIR or so?


Because:

> 2575  19:27:45.464196 openat(AT_FDCWD, "/tmp/test-tmp-ametzler/Qqf3SE", O_RDONLY) = -1 EACCES (Permission denied)

I wonder about that /tmp/test-tmp-ametzler.


The apparmor rules might just allow /tmp/*, not /tmp/something/*.


Ah, yes:

Indeed, if I set TMPDIR=/tmp/test I get that

"This PDF file is encrypted and can't be opened".


dmesg shows e.g.:

"[  692.0171072] audit: type=1400 audit(159265461.660:88): apparmor="DENIED" opereation="open" profile="libreoffice-xpdfimport" name="/tmp/test/4DyliY" pid=2661 comm="xpdfimport" requested_mask="r" denied_masj="r" fsuid=1000 ouid=1000"

And indeed, if I set that profile to complain only it works.

If *you* change stuff *you* have the responsibility to change stuff so that it works with it. This is not a bug here.
