Comment 0 for bug 1875774

This is testing was performed as a result of a user support request on a fresh install (screen position & wallpaper changed; nfs-common added & that's about all)

https://discourse.lubuntu.me/t/no-authorization-after-adding-user/1033/

A new user was added "pw_admin", logout & some testing done without issue.

I logged back in as me and tried to remove "sudo" rights from "pw_admin" user logged in as "guiverc" which is where I first had noticed this error.

On testing, it appears to occur on retracting/removing rights rather than adding them, and after the privileges are added only (though my testing is incomplete; takes awhile for rights to drop & thus be asked again; no issue if elevated-privileges already exists it so far appears to me)

Expected Result:

The 'sudo' permission gets removed

Actual Result:

I get an error show in discourse site, or uploaded here

When the error pop-up (

"Action (usermod) failed:
Error executing command as another user: Not authorized
This incident has been report" occurs

the following is written to `dmesg` output
