I am using Evince document viewer as default in ubuntu 12.04.

How do I get a hyperlink to open when clicking on it?

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.

    If by any chance it didn't work just open the file again, erase the same lines, save it and run sudo apparmor_parser -T -W -r /etc/apparmor.d/usr.bin.evince again. – JorgeArtware Jul 09 '13 at 08:53
  • I went through all of this, as well as other stuff here, but haven't been successful yet, I still get the same error: https://askubuntu.com/questions/997511/how-to-open-a-link-in-a-pdf-with-the-error-unable-to-open-external-link-faile. – James Ray Jan 19 '18 at 03:53
  • I am having the same issue. Is this still a bug in 20.04? I feel like this was probably fixed the last ten years and I am dealing with something else. – Kvothe Mar 21 '22 at 11:34

  • Open the /usr/share/applications/mimeinfo.cache file.
  • Search for the lines containing x-scheme-handler/http= and x-scheme-handler/https=.
  • You should have either firefox.desktop or any other browser name followed by .desktop after the text in those lines.
  • For example the line may read:
x-scheme-handler/http=firefox.desktop;
x-scheme-handler/https=firefox.desktop;
