* debian/control: - Fix liblightdm-qt5-3-dev to depend on qtbase5-dev, not libqt4-dev -- Michael Terry <mte...@ubuntu.com> Wed, 03 Feb 2016 13:45:53 -0500 ** Changed in: lightdm (Ubuntu Xenial) Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1540933 Title: /var/lib/lightdm not created by default Status in lightdm package in Ubuntu: Fix Released Status in lightdm source package in Wily: Fix Committed Status in lightdm source package in Xenial: Fix Released Bug description: [Impact] After apt-get purge lightdm the /var/lib/lightdm folder is deleted and then never recreated reinstalling the lightdm package. The folder is necessary due to the create of the .Xauthority file. [Test Case] 1. $ sudo apt-get purge lightdm 2. $ sudo apt-get install lightdm Expected result: LightDM starts Observed result: Lightdm can't start. Manually creating /var/lib/lightdm and chown lightdm:lightdm makes it work. [Regression Potential] Low. The change is to not remove /var/lib/lightdm on package removal. This directory should only be removed when the user is removed.
