I use Linux Mint 18.2. Some time ago tried manually update Linux kernel. It was unsuccessful and I rolled back on previous kernel version, but faced with issue that Update Manage not work any more: It launches but show empty list. But if I start it with sudo it works.

I tried to purge it in install again, but it does not help.

How to make it works without sudo again?
