INSTALLING IN KDE NEON 5.20.5

[Dmitriy]

Hello.
There was a problem with dependencies when installing Veyon in KDE Neon 5.20.5 ( 20.04 LTS).

cat veyon-ubuntu-stable-focal.list
deb http://ppa.launchpad.net/veyon/stable/ubuntu focal main

apt-get install veyon

Some packages cannot be installed. Perhaps what you ask for is
is not feasible, or you are using an unstable version of the distribution where
the packages you requested have not yet been created or have been removed from Incoming.
The following information may help you:

The following packages have unmet dependencies:
 veyon: Depends: qtbase-abi-5-12-8
E: Unable to fix errors: you have broken packages fixed.

Please tell me how to fix this problem?

Neon Qt version not compatible.

Exactly, it looks like KDE NEON is not fully binary compatible with Ubuntu 20.04. I suggest to build the Veyon package on your own as described here: https://github.com/veyon/veyon/blob/master/README.md#veyon-on-linux
