Instance issue on Ubuntu 24.04
If you can open Linked Helper Launcher window but an instance fails with 'Disconnect fired' error, then the issue is connected to the security updates on Ubuntu 24.04 (click here for more info). There is a workaround you can use to disable them till we implement a fix.
Here is what you need to do:
- Ope Terminal:
- Paste the line below and hit Enter:
sudo crontab -e -u root
- Enter your user password and hit Enter button again.
- If you're asked to choose an editor, then enter 1 and press Enter:
- In the opened text editor, move the text caret down to the end of the file using the arrow down button and paste these two lines:
@reboot sudo sysctl -w kernel.apparmor_restrict_unprivileged_unconfined=0
@reboot sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0
- Press Ctrl + S to save the file:
- Press Ctrl + x to exit
- Reboot the PC
- Try running Linked Helper Instance again.
Running Linked Helper as root
Due to security restrictions, Linked Helper cannot be started on behalf of root user. You can only start it from a regular user that is added to the sudo group.
To fix the issue, you need to:
- create a new user on your system;
- log in under that newly created user;
- install Linked Helper for that user as per instructions from the website;
- run the program.
