Problems running some commands with sudo

[Ashde]

Hi, I've tried everything I can find and I don't know where to go from here.

Running Debian 10

Running 'sudo virt-manager' results in the following:

Code: Select all

No protocol specified
Unable to init server: Could not connect: Connection refused
No protocol specified
Unable to init server: Could not connect: Connection refused
No protocol specified
Unable to init server: Could not connect: Connection refused

(virt-manager:11107): Gtk-WARNING **: 11:22:57.950: cannot open display: :0

Something similar also happens with 'sudo nautilus'

Code: Select all

** (nautilus:11210): WARNING **: 11:25:23.016: Error on getting connection: Failed to load SPARQL backend: Error spawning command line ?dbus-launch --autolaunch=b96e71e6e1714e77a7498f75a0399479 --binary-syntax --close-stderr?: Child process exited with code 1

(nautilus:11210): Gtk-WARNING **: 11:25:23.021: cannot open display: :0

...and finally running 'sudo seahorse'

Code: Select all

No protocol specified
Unable to init server: Could not connect: Connection refused
seahorse: Cannot open display: 

These are the only three I've found that have this problem. Included them together because they seem like they may be caused by the same problem.
Running without sudo works normally.

this problem

It's not a "problem", those applications are forbidden from running as root by design. I presume this is the GNOME desktop?

They can be made to work under sudo:



But I'm not telling you how I did that

Why do you want to run those programs as root anyway? What is it you are trying to do with them?

virt-manager will run fine on a root desktop. Never does it need sudo. The regular user doesn't need root or sudo, just be in the right group.

When selecting my ISO for a new VM (which is on a different drive) I get "The emulator may not have search permissions for the path '/pathto/.iso/'" and asks to correct that. It can't actually change the permissions though, and I was told to try running virt-manager with sudo and then doing the same thing.

And yes, GNOME desktop.

'/pathto/.iso/'"

from wherver the iso is link it to the standard directory
Example of a thunar custom action

Code: Select all

sudo ln -s --target-directory=/var/lib/libvirt/images %f

Then select the iso from the default storage pool.

Whoever told you that is an idiot, don't listen to them.

Running 'sudo virt-manager'

But why? Why do you need sudo privileges? Bad habit, or you came from Windows land? Anyway, don't do that! I'd facepalm, but we're not supposed to touch our faces any more.

Maybe this guy is an idiot, or maybe he’s a cyber criminal ...who knows...

Some morons think sudo is like bacon--it makes everything better.
