[SOLVED] Authorization [for mounting external partition] Failed for Some Reason

[dhinds]

After an upgrade and rebooting, when I attempted to mount the three external partitions I always use with any OS on this desktop computer with an Intel CPU, I get the following error message:

Authorization Failed for Some Reason.  Not authorized to perform operation.

Also, I was unable to sudo.  (I had made no changes to that).  No password would work.

So I logged out and logged in as root, then added the user dhinds to the disks group. But that didn't work when I logged back in. Then I added dhinds to the root, adm and fuse groups.

But that didn't help.  I still can't mount those partitions as the user (only as root).

I did change the dhinds password though with no problems (if I don't forget it).

Any suggestions?

TIA

Sorry about that.

A brand new and updated installation of Sparky Testing (that's all I use) LXQt, 64 bit.

(Everything was working fine).

Could this be an fstab problem?

I don't think so.
The latest LXQt provided a new authentication mechanism.
Make sure you have installed 'lxqt-policykit' package.
If you installed it right now, have to reboot.

I'll boot into Sparky LXQt now and check.

First I'm doing an apt full-upgrade --no-install-recommends -y --force-yes

System is now up to date.

lxqt-policykit is already installed.

I reinstalled it and will now reboot.

(Maybe I should have removed it and then reinstalled it).

I noticed that synaptic would not open at first via the lxqt panel menu.  (It too said "Authorization failed for some reason"). I had to open a terminal and used sudo (which now has a stronger password).

The problem persists unchanged, after rebooting

Do you suggest I remove lxqt-policykit or remove lxqt-policykit completely, then reinstall it, or ??

TIA

Check does the policykit work:

Code Select Expand

pidof lxqt-policykit-agent
If the output is empty, run it:

Code Select Expand

lxqt-policykit-agent
Then check again.
If not empty now, try to mount an external disk.

Somebody posted the same problem on our Polish forums too.
It's already fixed (hope so), so:

Code Select Expand

sudo apt update
sudo apt full-upgrade
sudo reboot

[dhinds]

Check does the policykit work:

Code Select Expand

pidof lxqt-policykit-agent

Nothing came back.

If the output is empty, run it:

Code Select Expand

lxqt-policykit-agent
Then check again.
If not empty now, try to mount an external disk.

This is the result:

Code Select Expand

Now I'll try that

[dhinds]

Yes, that did the trick.

Good job, pavroo
