I'm trying to install Xpra, however it seems that there are missing packages I cannot install. Xpra fails with the following error:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 xpra : Depends: xserver-xorg-video-dummy but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Attempting to install this package fails as it depends on xorg-video-abi-18, which is not included in the manually installed xserver-xorg-core package, nor does it have an installation candidate.

Package xorg-video-abi-18 is a virtual package provided by:
xserver-xorg-core 2:1.16.4-1 [Not candidate version]

E: Package 'xorg-video-abi-18' has no installation candidate

I have not held packages, as the answer for a similar error does not apply.

The OS I'm using is Raspbian

  • Which OS are you using? Raspbian?

  • Try installing xorg-video-abi-18, if not try installing xserver-xorg-core-udeb.

  • Neither helped @tlhIngan, unable to locate package xserver-xorg-core-udeb and xorg-video-abi-18 has no installation candidate.
