Hi
It looks like you are running the PPA version. One upgrade (5.1 -> 5.4)
caused a problem by creating a few root-owned files (update-manager did not
honour DOT_SAGE, so we added HOME afterwards as well).
It may have created two or three files as root in the process. You can get
rid of them with
cd; sudo find .sage -uid 0
and add to that "-exec rm -f '{}' \" to remove them; or set the owner back
to yourself with chmod.
This problem is not present in the new PPA, but once it happened you need
to fix these permissions.
Regards,
Jan
