I am currently using jackd2 version 1.9.19~dfsg-2ubuntu1 from the jack2 ppa (https://launchpad.net/ubuntu/+source/jackd2/1.9.19~dfsg-2ubuntu1). However, apt really wants to update from the kxstudio repo (https://kx.studio/Repositories) instead, despite being incompatible for Ubuntu wine (https://wiki.winehq.org/Ubuntu). I have dealt with this for the last couple of months by apt-mark holding the package but it would be better if there was a way to disable the kxstudio specifically for this package.

Edit: The kxstudio are not specifically for jack, it also contains other software I use and want to receive updates for.

  • Hello. what version of Ubuntu are you using? Did you add the PPA for this kxstudio repo (kx.studio/Repositories)?

  • 21.10. Yes, I installed their repo .deb which automatically installed a couple of PPAs

  • So if you removed that PPA it would not update that software. From your question that would seem to fix it.

This can be controlled by setting priorities in the APT system.

Create a configuration file under /etc/apt/preferences.d/, eg. /etc/apt/preferences.d/kxstudio, and tell there that jackd2 should not come from this PPA if there is a decent alternative, as follows:

# Never prefer other packages from the kstudio repository
Package: jackd2
Pin: release o=####
Pin-Priority: 1

To find the value of ###, the string that specifies the origin, run the command apt-cache policy and see the value for o= below the line for the PPA in question.

Set Pin-Priority to a negative value to prevent that version from ever being installed, even if it is available nowhere else.
