Can't load shared library libQt5Core.so.5 – Debian

This question has been asked before, but the fixes don’t work for me. I am running Windows 10 with WSL (Debian) and I am unable to run a QT program because of the error

texconv: error while loading shared libraries: libQt5Core.so.5: cannot open shared object file: No such file or directory

I found a post which discusses the same problem. I’ve tried tolos’ and Envek’s solutions, but they don’t work for me. For me the file is under /usr/lib/x86_64-linux-gnu/ like tolos’ was. I also sudo-ed the strip and recompiled the qt program (If that even matters), but it still doesn’t work.

If it matters, my kernel version (checked with uname -r) is 4.4.0-18362-Microsoft and I have no issues running this qt program on my other PC that uses WSL Ubuntu. And I installed the qt stuff with this command: sudo apt-get install qt5-default qtbase5-dev

    I got it working in the end. I upgraded from WSLv1 to WSLv2 and that solved it. Not sure why, but it must have been a WSLv1 Debian bug

    I had an image that I would run using docker run and which would successfully launch KStars — an application that uses this libQt5core.so.5.

    If I ran the very same image on a Kubernetes cluster then I would get an error message when launching KStars like libQt5Core.so.5: cannot open shared object file: No such file or directory or some such.

    Putting this strip command into the Dockerfile and rebuilding the image allowed the application to load successfully in both environments.

    sudo strip --remove-section=.note.ABI-tag /usr/lib/x86_64-linux-gnu/libQt5Core.so.5
