To work around the problem set in ~/.profile the system default value for XDG_DATA_DIRS and to GSETTINGS_SCHEMA_DIR.

export GSETTINGS_SCHEMA_DIR=/usr/share/mate:/usr/share/mate:/usr/local/share/:/usr/share/:/var/lib/snapd/desktop

export XDG_DATA_DIRS=/usr/share/mate:/usr/share/mate:/usr/local/share/:/usr/share/:/var/lib/snapd/desktop

great idea! I had this issue too. If you want to have x2go with Mate working for all users enabled I would put this

export GSETTINGS_SCHEMA_DIR=/usr/share/mate:/usr/share/mate:/usr/local/share/:/usr/share/:/var/lib/snapd/desktop
export XDG_DATA_DIRS=/usr/share/mate:/usr/share/mate:/usr/local/share/:/usr/share/:/var/lib/snapd/desktop

into /etc/profile instead. Have fun!

same thing on xfce4 but I didn't have the same error message: more a lot of error message as:

now its working by just adding the 2 lines from your post and change mate to xfce4
