[zsh] zsh compinit: insecure directories

This morning, some packages in my system updated, and left me with this error message. I am using Ubuntu 18.04.

Apparently, something in the update changed the username and group to numbers, instead of root, as so:

# There are insecure files: /usr/share/zsh/vendor-completions/_code
# sudo ls -alh
-rw-r--r-- 1  131  142 2.6K 2019-10-10 16:28 _code

I simply changed the user and group for this file back to root and the problem went away. I did not need to change any permissions, and would caution against doing so unless the underlying cause of the problem is understood.

sudo chown root _code && sudo chgrp root _code

After switching 131 and 142 back to root, this error message from zsh went away.
