unable to mount anything

[desperado]

Hi,
Everything worked fine with Stretch for about a year. After the last update I'm not able to mount anything - USB stick, external disk, another internal disk. Password is not recognized if I try to open root console, apper and discover don't even ask for authorization - I'm not allowed to do anything. Googled around for a couple of weeks and read the forums, seems to be something to do with policy kit and udisks, about 1/3 of the cases like me just reinstalled. I'm a simple, stupid user, not good in code, is this really the only solution? Please, help.

Do you use sudo?

Code: Select all

sudo -i

Or su?

Code: Select all

su -

The root password can be reset fairly easily even if the remaining users do not have elevated permissions, ask the interweb how.

I can do sudo -i. The password is recognized, but there is no prompt to mount, just 'no authority'. I followed advice from some other threads, seems there is no authentication agent running, but sysmonitor shows kde authentication agent 1. Not recognized?

there is no prompt to mount, just 'no authority'.

How exactly are you trying to mount the devices? Have you checked the systemd journal for any error messages?
