How to list third party packages

Asked by paul ritchings on 2013-02-14

I would like to find a way to list third party packages /software prior to an upgrade. It may be that these are not important but it would be helpful to identify them before potetially making them unusable.

Can you define what you mean by 'third party' please. Packages installed from the official repos after install are not 3rd party.....

That's what I understood too.

I am managing something started by others. I am trying to make sure that my upgrade doesn't break anything.

Third party would software packages installed later, after the main install.

/var/log/dpkg.log will show packages being installed and removed.

Synaptic package manager allows you to list installed packages by origin. There you can see if packages have been installed from PPAs or manually directly from .dep packages. Maybe that provides the information you are looking for.


/var/log/dpkg.log is empty. I don't think that necessarily means no further installs have taken place. The real log in use may simply be in another location.

Manfred Hampl:

This is server version. there is no gui.

Is there a way to do this with apt-get. I have looked but can't find anything so far.

Thanks for the information.

The information must be somewhere (I guess in the /var/cache/apt/status file), as it is possible to display it with 'apt-cache policy packagename'. Maybe apt-cache or dpkg-query can be used to display the information that you need.

Can you help with this problem?
