I'm getting this error message:

"Incorrect permission on /usr/lib/policykit-1/polkit-agent-helper-1(need to setuid root)"

Due to this problem I can't download any app.

This is the solution I came up with and tried, and it seemed to work, not sure why the permissions changed on this file though.

sudo chmod 5755 /usr/lib/policykit-1/polkit-agent-helper-1

I also saw a version that tried: sudo chmod +s ... I originally opted to mirror the other permissions for the files in /usr/lib/policykit-1/

  • From @ericx see comments: Or, more correctly try: Chmod 4755 and for an extra level for the paranoid try: Chmod 4555
