Hello. Sebastien, there is a good news. On Mon., Jul. 22, Evince has been updated to 3.18.2-1ubuntu4.6 version to fix one security issue (buffer overflow; CVE-2019-1010006)*. And now, I can open '.pdf' files again!
I think, that reinstalling Evince package, also could help - I mean with problem I described, because `debsums(1)` showed, that MD5 sum for 'libpdfdocument.so' and 'libdvidocument.so' files does not match so reinstall - probably - was a solution. However, I have not any possibilities to check this. Thank You and I apologize one more time for such a long time without my answer. Thanks, best regards. _____________________ * https://lists.ubuntu.com/archives/xenial-changes/2019-July/025019.html ** CVE added: https://cve.mitre.org/cgi- bin/cvename.cgi?name=2019-1010006 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1835285 Title: PDF files don't open; "Failed to load backend for 'application/pdf': libpdfdocument.so" and "Invalid ELF header".
