Incorrect permissions on polkit-agent-helper-1

[Laura Czajkowski]

I upgraded from 17.10 to 18.04, I ran
czajkowski@penny:~$ sudo do-release-upgrade
czajkowski@penny:~$ sudo apt update && sudo apt dist-upgrade
czajkowski@penny:~$ sudo apt install update-manager-core

Upgrade then started and about 4 mins the Error 1 image appeared, Incorrect permissions on /usr/lib/policykit-1/polkit-agent-helper-1(needs to be setuid root)

a few mins later the login appeared for me to enter my password, it would not recognise my password Error 2.

I'm sorry it is not clear to me but when did you see the error message? Was it during the release upgrade process, after you ran "do-release-upgrade" or was it when you did some apt operations after the upgrade completed successfully?

Hi Brian

sorry I wasn't clearer, it happened as soon after the upgrade gui was launched and then the dialogue box appeared over the text box that was updating in the background

I don't believe this has anything to do with the release upgrader, it just happened to be the process which caused you to notice that the permissions were incorrect.
