I've installed ubuntu 12.04 and installed okular but with normal user i can't run okular and give me an error that "Unable to find the Okular component." but with root user i can run it without any errors. what should i do?

I've tried to purge and install okular itself, but this has not worked.

  • How did you install Okular? With Ubuntu Software Center or sudo apt-get install or ...? – Jakob May 08 '12 at 07:41
  • Same issue as https://askubuntu.com/q/1070081/446253 which pinpoints problems with q5, like https://askubuntu.com/q/1114346/446253. These refer to release 18.04, so it's a recurring glitch – XavierStuvw Dec 15 '19 at 09:09

You should never run GUI programs as root unless explicitly noted. Changes are that files in your home directory now have wrong ownership. Find those files and restore the ownership:

  1. Open a terminal

  2. (optional, but recommended for verifying) Find all files that are not owned by you:

    sudo find ~ ! -user $(id -u) -ls

  3. Find all files and restore the ownership to yours:

    sudo find ~ ! -user $(id -u) -exec chown $(id -u) {} \; -ls

If unsure, you can leave a comment here with a link to http://paste.ubuntu.com/ containing the output of step 2.
