I have Ubuntu 20.04 running on my system and was using the pdf-viewer Okular until recently. However, now Okular does not start when double clicking on a pdf-file and starting from the terminal gives the following error message:
okular: /snap/okular/109/kf5/usr/lib/x86_64-linux-gnu/libQt5Core.so.5: version `Qt_5.15' not found (required by okular)
Any ideas how can I fix that?
I was thinking of trying sudo apt-get install qt5-default which I found on https://wiki.qt.io/Install_Qt_5_on_Ubuntu but this is the command for Ubuntu 12.10 and there it says explicitly that it will produce an error on Ubuntu 16.04. Since I did not want to break my system, I decided to post a question here before trying anything.
I will appreciate any advice on how to get Okular running again.

Remove Snap version by
snap remove okular
and install deb-packaged version instead by
sudo apt-get install okular

I had the same problem in Ubuntu 16.04, apparently snap package is not working anymore and is not even listed anymore on Okular website. Instead the flatpak package works. So solution for me was to remove snap package and install the flatpak one.
