Apt repo conflict - qtbase5-dev / rbp2-mesa-osmc


It seems that there is a conflict between OSMC & debian repo’s.

When I try to install “qtbase5-dev” package (distributed by debian repo), i cannot because of “rbp2-mesa-osmc”.

Here is the apt install log :

sudo apt install qtbase5-dev

Do you think you can do something?


  1. Login via the command line
  2. Run the following command to add the staging repository:
    echo 'deb http://apt.osmc.tv bullseye-devel main' | sudo tee /etc/apt/sources.list.d/osmc-devel.list
  3. Run the following commands to update: sudo apt-get update && sudo apt-get dist-upgrade && reboot
  4. Your system should have have received the update.

Please see if the issue is resolved.

I also recommend you remove /etc/apt/sources.list.d/osmc-devel.list after updating.

This will deactivate the staging repository. You can do so with the following command:
sudo rm /etc/apt/sources.list.d/osmc-devel.list.

Please note that we will automatically disable this update channel after 14 days on your device in case you forget to do so to ensure that your system reverts to the stable update channel.

Hello Sam,

Thanks for your fast answer :slight_smile:
Everything seems to work.

Have a good day!!
