Ubuntu – Why don’t hyperlinks open in evince document viewer

You encountered a bug but there is a quick fix, I just did it and it worked, thanks to @maggotbrain by the way. He pointed me to this comment, and the suggested solution worked. So I was able to fix this issue with google chrome by doing the following:

1. Open a terminal, type gksudo nautilus and hit enter,type your password and hit enter again, so now you are running nautilus with root privileges.
2. On nautilus go to /etc/apparmor.d/abstractions/

3. Open the ubuntu-helpers file and locate this lines inside:

   # Allow exec of libexec applications in /usr/lib*

   /usr/lib*/{,**/}* Pixr,

4. You will insert this block of text after those lines:

   # From https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/964510/comments/12
   # While the chromium and chrome sandboxes are setuid root, they only link
   # in limited libraries so glibc's secure execution should be enough to not
   # require the santized_helper (ie, LD_PRELOAD will only use standard system
   # paths (man ld.so)).
   /usr/lib/chromium-browser/chromium-browser-sandbox PUxr,
   /opt/google/chrome/chrome-sandbox PUxr,
   /opt/google/chrome/google-chrome Pixr,
   /opt/google/chrome/chrome Pixr,
   /opt/google/chrome/lib*.so{,.*} m,
   

   but before this line:

   # Full access
   

5. Save the file, close nautilus.

6. Finally, type sudo apparmor_parser -T -W -r /etc/apparmor.d/usr.bin.evince on the terminal and hit enter, wait a few seconds until there is a line break and the cursor is awaiting for new input, this means the command went through with no problems :) hope it was helpful.
