I have the this problem on Xenial. Double slash in XDG_DATA_DIRS and a minus in XDG_CONFIG_DIRS.
Even worse, when I tried to append paths for Flatpak to XDG_DATA_DIRS using an .env file in my home directory, the result was so broken that Plasma failed to start. I've undone the change since then, but I remember a double colon in there, and my additions appearing in the middle of the string rather than the beginning or end as expected. This seems rather serious to me. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1706126 Title: XDG_DATA_DIRS XDG_CONFIG_DIRS MANDATORY_PATH DEFAULTS_PATH are not set correctly To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/1706126/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
