PyQt5 gotcha: git-cola gives misleading "PySide module not found" error

[kmbgit]

Running Ubuntu 20.04 under Windows 10 WSL I get a No Qt bindings could be found error even though PyQt5 is installed as a dependency of git-cola by apt install. The problem is that libQt5Core.so.5 fails to load because it calls a kernel function that doesn't exist in the distribution I'm using. The fix is to run sudo strip --remove-section=.note.ABI-tag /usr/lib/x86_64-linux-gnu/libQt5Core.so.5. See https://askubuntu.com/a/1163268/358938 for the discussion that led me to this fix.

I know this isn't git-cola's fault, but hopefully others will find this solution when they search for the same symptom as me.

During handling of the above exception, another exception occurred:
