I will, although I use clangd which I suspect is pretty heavily tested
anyway.

I donʼt think magit or helm are to blame here.

`list-packages' seems to get confused about which dependent packages
need to be uninstalled, and sometimes uninstalls too many (or maybe it
fails to upgrade them, Iʼm not sure). I then get errors about 'package
bar requires package foo version 1.12, only found 1.11' or similar.

Every time it happens I manually install the packages that should not
have been uninstalled, and get on with other things, since I donʼt
normally have time to spend on creating a minimal test case.

Now you understand why I only upgrade my packages every couple of
months.
