I installed Ubuntu 20.04 on a new partition less than a week ago. I have not yet gotten all the basic stuff to work. But now, from time to time, 20.04 pops up a small window saying "Authentication is required to run gvfsd-admin daemon". But even though I enter my Ubuntu password and press it will not go away. Not even if I press the Cancel-button. Which, by the way, is a bit difficult to do, because instead you activate functions in a window BEHIND the authentication-window(!!) The only way of making the screen usable again is to restart Ubuntu... VERY annoying!

If one of the users in our group tries to login to his desktop computer, he gets a popup "Authentication required to refresh system repositories". When I type in my administrator password in this popup, the popup does not disappear. It seems that only a hard reboot solves the problem temporarily, because after a few days the same popup appears again. When I login as a user with sudo privileges, though, everything works fine. The operating system is Ubuntu 19.10.

The user has no scripts running on startup, other than loading his bashrc and setting his environment variables.

I already searched the internet, but I have been unable to find a solution (I have done the most recent upgrades). I would really appreciate your help.

I'm trying to use apt-get command on a network that uses a proxy, like this:

We use 10.114.7.7 on port 80 as Http-proxy, and after that an authentication window comes up, asking for user name and password.

Our Username/Domain is like this: [email protected]

I'm wondering, how i can use http_proxy=http://User:Pass@Proxyserver:Port in this situation!? I also tried both, 10.114.7.7 and urmia.ac.ir as Proxy server but no result!

I'd like to allow SSH password authentication from only a certain subnet. I see the option to disallow it globally in /etc/ssh/sshd_config:

# Change to no to disable tunnelled clear text passwords
#PasswordAuthentication yes

Is there a way to apply this configuration to a select range of IP addresses?

I was able to setup ssh to use private/public key authentication. Now I am able to do

ssh user@server1

And it logs on with the private key. Now I want to connect to another server and use a different key. How do set it up so

ssh user@server1

uses privatekey1

ssh user@server2

and uses privatekey2
