[SOLVED] The gtk apps don't ask for the root password.

When I run the:

timeshift-gtk

I'm getting this output

timeshift-gtk
E: Admin access is required to backup and restore system files.
Please re-run the application as admin (using 'sudo' or 'su')

(timeshift-gtk:93742): Gtk-CRITICAL **: 23:13:16.919: gtk_icon_theme_load_icon_for_scale: assertion 'GTK_IS_ICON_THEME (icon_theme)' failed

** (timeshift-gtk:93742): CRITICAL **: 23:13:16.919: gee_abstract_collection_get_size: assertion 'self != NULL' failed

I guess it's somehow related to the polkit. Any idea how can I fix it?

It's gtk application. I want to be able to run it from the applications launcher. In distributions like Linux mint it asks for the password when I launch it.

What groups is the user you started timeshift-gtk a member of? From the contents of /usr/share/polkit-1/actions/in.teejeetech.pkexec.timeshift.policy

your guess it is polkit related appears correct.

Re: [SOLVED] The gtk apps don't ask for the root password.

What is the output when you run `groups` as the same user you have the issue running `timeshift-gtk` as?

Do you have polkit and a polkit authentication agent installed?

pacman -Qs polkit

I manually run the

/usr/lib/polkit/polkit-kde-authentication-agent-1

and

hyprctl dispatcher exec /usr/lib/polkit-kde-authentication-agent-1

, then tried to launch the timeshift-gtk, but still have the same result

Re: [SOLVED] The gtk apps don't ask for the root password.

I want to be able to run it from the applications launcher.

Run what, how?
The desktop entry in the package runs timeshift-launcher which in turn checks $- and $XDG_SESSION_TYPE to determine what it'll do and either run su, pkexec or su in a terminal.
Punching "timeshift-gtk" into a terminal will not work resp. consistently lead to that result.

If you want to debug the timeshift-launcher script add

exec 1> /tmp/timeshift.dbg 2>&1
set -x

below the shebang and click your icon that doesn't work. Then inspect /tmp/timeshift.dbg

Re: [SOLVED] The gtk apps don't ask for the root password.

Which is entirely not a trace of the timeshift-launcher script but from https://github.com/linuxmint/timeshift/ … t-launcher it looks like you entered the wayland/pkexec branch but the script doesn't import the relevant environment - this is probably a wayland specific issue.

https://github.com/linuxmint/timeshift/issues/206
Next to just inheriting the entire environment you could adapt https://gist.github.com/AladW/de1c5676d93d05a5a0e1 - obviously don't inherit it from xinit.

I created the timeshift.sh shell script that executes the

bash -c 'pkexec env $(env) timeshift-launcher'

, and replaced the Exec line in the desktop file to execute that bash script.
