Update Manager not prompting for password - Mint17 MATE xrdp

[InvisibleAgent]

Hi all,

I'm running Mint17 64-bit MATE over xrdp to Windows 7 over RDP, and Update Manager no longer prompts me for my root password when I click "Install Updates" - the windows just closes. I don't recall any changes that caused this to happen (and it did work previously). Synaptic prompts for a password as expected, as does Software Manager, and apt-get works as expected, just frustratingly Update Manager doesn't. It correctly displays the (i) when there are updates, gives me a (check) mark when I manually apt-get install/apt-get upgrade, and Refresh works as expected.

The Update Manager correctly prompts me for my root password when I login to the box directly, it only fails to prompt when I login via xrdp.

Looking in the information window, I see the following:

Error creating textual authentication agent: Error opening current controlling terminal for the process ('/dev/tty'): No such device or address
++ Return code: 127
++ Install finished
++ Starting refresh
++ Found 82 recommended software updates
++ Refresh finished

I've tried several things all to no avail, including:

- apt-get update / apt-get upgrade
- apt-get dist-upgrade
- forcing reinstall of the Update Manager package through Synaptic

Machine details: CPU~Dual core Intel Core i5-4250U CPU, Kernel~3.13.0-24-generic x86_64

This feels like a configuration file got changed somewhere, but I've been unable to figure it out.

Any ideas?

Thanks!

Code: Select all

sudo apt-get install -s mintupdate; aptitude show mintupdate;

copy paste into terminal and run. Will show the installed version and the latest available.

Also run this in terminal and see if the update opens OK.

Code: Select all

mintupdate

Thanks Spearmint2! Here's the output:

Running 'mintupdate' from the command line correctly launches the Update Manager (as does clicking on its icon in the system tray).

OK, then change the command line on the launcher, or make a new launcher and point to it for one of the programs at startup.

Looks familiar - check this thread.

Aha! That seems to be what I was hunting for. Thank you Monsta, I'll see if that info helps me fix my issue and report back.

Hello. Have same problem as TS:

Error creating textual authentication agent: Error opening current controlling terminal for the process ('/dev/tty'): No such device or address

Neighbour topic didn't solve issue for me:
I don't have polkit agent at all (I have a disabled link to it in startup apps though).
Any help?
