Ubuntu Mainline Kernel Installer

Can't update to 5.18.8 because of pkexec

Asked by Paul Ubuntu

sudo chmod -s $(which pkexec)

After fallowing the advice https://www.esecurityplanet.com/trends/hacking-linux-is-easy-with-pwnkit/ sudo chmod -s $(which pkexec) I get pkexec must be setuid root when trying update the kernel.

How do I repair? How do I reverse sudo chmod -s $(which pkexec)

Try

sudo chmod +s $(which pkexec)

Remark:
The workaround with "chmod -s" should not more be necessary. The program has already been patched, see https://ubuntu.com/security/cve-2021-4034 with https://ubuntu.com/security/notices/USN-5252-1 and https://ubuntu.com/security/notices/USN-5252-2
