All works well here. Can't reproduce this issue.

How can I reproduce it in other machine? What can I do? Reinstall Linux Mint? Any logs can I see?

But remains in taskbar and it is not shown.

What happens when you click on the icon in the taskbar?

Also, what happens if you type

gnome-calculator

into a terminal?

Do you have any broken packages? Please use synaptic-pkexec and look at Status.

[danielgiljara]

0 broken packages.

[claudiux]

Please give the result of the command:
ls -l /run/user/1000/at-spi/

On my computer:

total 0
srwxrwxrwx 1 <user> <group> 0 juil. 26 13:44 bus_0

EDIT: Also give the result of the commands:
sudo systemctl status dbus.service
sudo systemctl status dbus.socket
(Press Q to quit each of these commands.)

[danielgiljara]

I will reinstall Linux Mint. By some reason that folder is not working on my system. Both services are working.

[danielgiljara]

Well, I don't know if want to continue with this issue.

The result of first command is:

daniel@daniel-IdeaPad-3-15ITL6:~$ ls -l /run/user/1000/at-spi/ total 0 srwxrwxrwx 1 daniel daniel 0 jul 26 18:27 bus_0

The result of systemctl on both services is "Active: active (running)".

[claudiux]

Yes, try to reinstall LM. I'm sorry I can't help you more.

[danielgiljara]

Ok! I will reinstall LM. Non deterministic behaviors!

Hi,
I experienced the same error on my freshly installed system, then after a long trial I became suspicious that the problem occurred after installing firejail. Of course I ran a few rounds of unnecessary reinstallations before... :)

~$ gnome-calculator

I ran it using --debug and lo and behold:

Finally, after identifying the cause of the error, I ended up here:
netblue30/firejail#4173

I hope this helps others too!

[danielgiljara]

Yes. I experienced the error dissapears when desinstalled firejail. Thanks for open the issue.

You can still use firejail, you just need to create a local profile for the calculator here:

EDITED:

The description below is incorrect, so I have crossed it out.
Thanks to rusty-snake for correcting me.
Please read rusty-snake's instructions!

/home/\\/.config/firejail/gnome-calculator.profile

and the gnome-calculator.profile should contain this:

private-bin gnome-calculator,sh
ignore include disable-shell.inc
include /etc/firejail/gnome-calculator.profile

For example:

mkdir -p ~/.config/firejail && echo "private-bin gnome-calculator,sh
ignore include disable-shell.inc
include /etc/firejail/gnome-calculator.profile" > ~/.config/firejail/gnome-calculator.profile

Br: Zsolt

A small addition:
This warning is not an error:
"Warning: cannot create /usr/local/bin/gnome-calculator - already exists! Skipping..."

This is because of what is written at the beginning of each profile file.

~$ cat /etc/firejail/gnome-calculator.profile
" # This file is overwritten after every install/update"

~/.config/firejail/gnome-calculator.profile overwrites the configuration file in your home directory with the ominous two lines, then appends the original configuration (from /etc/firejail/ ). So, you just added some extra lines to the original file.

[rusty-snake]

you just need to create a local profile for the calculator here:
/home//.config/firejail/gnome-calculator.profile

That's not the way you create a local override profile. It should be gnome-calculator.local. That way you can omit the installation dependet include /etc/firejail/gnome-calculator.profile.

Hi rusty-snake,
Thank you for correcting me and for your work in firejail! I have crossed out the part that was wrong.

Should I stop using this then:

Apart from the possibility to omit the import, is there a difference between ".local" and "customized profile"?

[rusty-snake]

Yes. Better use https://github.com/netblue30/firejail/wiki/Creating-overrides and https://github.com/netblue30/firejail/wiki/Creating-Profiles.

Not really, mostly convenience.
