That is not the only bug that has “slip through our radar”. The latest
update of Ubuntu MATE lies about the owner of files both in the command
line ls -l command and the Caja Properties window. Both claim the owner is
root. Since I am logged on a robert not root I would not be able to create,
modify, or delete any files in my system (ls always says to owner is root).
Since I can make changes then either the file system permissions code is
broken or the owner is being incorrectly reported.

I reported this problem about 4 weeks ago. It has “slip through our radar”.
No response from anybody despite the fact that this is a security problem
in the basic kernel.
