Comment 4 for bug 1770965

I will keep this bug open. It is a release critical bug since it causes the user to have an unusable system after upgrade.

If the lightdm configuration has the lightdm-kde-greeter configured as the greeter and if the user lets the upgrade remove the now obsolete lightdm-kde-greeter, the lightdm configuration should be modified to have no greeter configured. This will cause lightdm to use its internal greeter, and the user has a usable system and can take it from there.
