Dependencies problems in a fresh Ubuntu 20.04

Hello,

I’m installing the latest nightly version from repository on Ubuntu 20.04 but there is a problem with dependencies:

$ sudo apt install jitsi
Reading package lists… Done
Building dependency tree
Reading state information… Done
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:
jitsi : Depends: libavformat57 but it is not installable or
libavformat-ffmpeg56 but it is not installable
Depends: libavcodec57 but it is not installable or
libavcodec-extra57 but it is not installable or
libavcodec-ffmpeg56 but it is not installable or
libavcodec-ffmpeg-extra56 but it is not installable
Depends: libavfilter6 but it is not installable or
libavfilter-extra6 but it is not installable or
libavfilter-ffmpeg5 but it is not installable
Depends: libavutil55 but it is not installable or
libavutil-ffmpeg54 but it is not installable
Depends: libswscale4 but it is not installable or
libswscale-ffmpeg3 but it is not installable
E: Unable to correct problems, you have held broken packages.

There are installed new versions of the listed dependencies. For example libavformat58 instead of libavformat57.

How can I solve this problem?

Thanks,
Andrea
