[RESOLVED] icon tray copyq failure from root script

[jduns]

I have a root script to sync my files on a pen-drive. This script is a root one, because I have to stop (at the beginning) and restart (at the end) a mariadb server (I can do this only as root).
I have also to close (before syncing) and re-open (after syncing) copyq.
So far (before switch to 22.04 lts, I have KDE Neon) this code worked:

sudo -u myusername env QT_QPA_PLATFORM=xcb copyq exit​

and

sudo -u myusername env QT_QPA_PLATFORM=xcb copyq &​

Now the second code doesn't work anymore: the error message is

QtWarning: env says KDE is running but SNI unavailable -- check KDE_FULL_SESSION and XDG_CURRENT_DESKTOP​

Nothing to do, adding

export XDG_CURRENT_DESKTOP=KDE
export KDE_FULL_SESSION=true​

to my .bashrc.

To sum up: no way to restart copyq as user in a root script.
Any idea? A bug?

Thank you!

Does leaving out the env work? You might have to give the full path to copyq. Or, use bash -c

sudo -u myusername QT_QPA_PLATFORM=xcb bash -lc copyq &

Even with your code I get the same error message:

[default] QtWarning: QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '
/tmp/runtime-duns'
Warning: [kf.notifications] QtWarning: env says KDE is running but SNI unavailable -- check KDE_FULL_SES
SION and XDG_CURRENT_DESKTOP

Using "myusername" instead of my reale username (duns) I got this strange message (partly in Italian, I hope you understand):

sudo: unknown user myusername
sudo: errore nell'inizializzare il plugin di audit sudoers_audit

But I noticed that the problem is not that the copyq server doesn't start, but only that the icon tray of copyq is not visible.

EDIT

Indeed with this code

sudo -u duns env QT_QPA_PLATFORM=xcb copyq --start-server show
[1]+ Completato sudo -u duns QT_QPA_PLATFORM=xcb bash -lc copyq show

I have the server working, and the main window visible, but not the icon tray.
Therefore I have changed the title of this thread.

EDIT

There is a know bug about copyq icon tray: see https://github.com/hluk/CopyQ/issues/1973
But in my case starting copyq as user I have tray icon. The only problem is starting user copyq from a root script.

EDIT

I have opened a bug report here.

Today I was said to set the DBUS_SESSION_BUS_ADDRESS environment, but I don't know how.

It's tricky. See, f.ex., this post

Setting environment variables in your existing script won't affect the command being run by sudo -u, so I suggest another script that has the dbus stuff, then runs copyq, and the sudo -u runs that; cleaner that way IMO. Otherwise, your script could find the variables and add them to the command, like the QT_QPA_PLATFORM is set.

Thank you. I have solved! This code works:

sudo -u [myusername] env DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus copyq --start-server​
