Gupax hangs after attempting xmrig start - unable to authenticate to root? freezing GUI window/environment

[nova2moon]

Sorry, it posted prematurely, now editing....

OS & Version:

Operating System: Ubuntu 24.04.4 LTS Kernel: Linux 6.17.0-1023-oem

Bug

Running latest gupax as non-root (normal user), launches GUI, started node synching (at 30%) now try xmrig , enter key hash, and click START all with default values, causes GUI to feeze with logs of errors..

Steps

Steps to reproduce the behavior:
Downloaded latest tag.gz, ran gui and allowed it to pull all rest of binaries.. steps described above.

errors start with:

[INFO] [16.916] [<redacted>:0] XMRig | Entering watchdog mode... woof!

This appears like it tries to authenticate to root?? couldn't find any docs that say gupax needs root ? how to automate that? it depends on additional agent setup?

later more errors flood:

eventually the GUI locks up and stalls machine, only way out is kill -9..

it might start working once node is fully synced, not sure if related.

OH WOW, checking on very old machine running v1.3 when running xmrig it prompts:

--- Gupax needs sudo/admin privilege for XMRig! ---
with a place to enter root password.. that did not appear to happen on latest 2.0.1..

[Cyrix126]

The way gupax handles the authentication for launching xmrig with admin privileges has changed between v1.3 and v2.01.

Now it uses pkexec to handle authentication. You don't need to run gupax as root. pkexec will open a window (by calling your authentification agent, which is policykit) asking for a password by default on a fresh Ubuntu 24.04

If that's not the case, it is falling back on terminal input like we can see in your logs.

If your pkexec on your system is falling back on terminal input (You can test by simply testing the command pkexec),, it means your system has been modified. Please first resolve this issue first. On Ubuntu 24.04, you should have policykit installed and running.
ps aux | grep -i polkit

Wow, thanks for insight!
yes this is running:
polkitd 1157 0.0 0.0 390620 11816 ? Ssl May19 0:11 /usr/lib/polkit-1/polkitd --no-debug

These servers run without any display, connection is via VNC, x11 works fine, however, pkexec does not open a terminal window, it prompts text, same lines that appear in the log file!!
Reading online suggest to run with display variables like:

$ pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY ls

That did not work either.. full output for the record:

$ pkexec ls ==== AUTHENTICATING FOR org.freedesktop.policykit.exec ==== Authentication is needed to run /usr/bin/ls' as the super user
Authenticating as: user
Password:
polkit-agent-helper-1: error response to PolicyKit daemon: GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: No session for cookie
==== AUTHENTICATION FAILED ====
Error executing command as another user: Not authorized

This incident has been reported.
`

reading further suggests that the auth agent is not part of icewm, so need to add it to xstartup in .vnc, and now it's running:

user 776378 159740 0 22:01 pts/7 00:00:00 /usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1
now, that's the SOLUTION!!! Sure enough, "ls" worked (by first prompting on X11/gui, also gupax is launching xmrig properly..

Thanks, maybe some validation could run before hand and alert user in a more "streamlined" fashion :)
