Comment 19 for bug 1801290

If the issue is that latte cannot run with a stale qml cache in ~/.cache/lattedock/qmlcache/ then this is an upstream KDE issue that cannot be addressed in distro packaging. We can't and shouldn't act on any file in a user home when doing a package upgrade via sudo/admin. This should be fixed by KDE by having latte detect that it is being run for the first time by a user after a version upgrade, and at that point removing or modifying the cache with that user's privileges.
