In ubuntu 20.04 (upgraded from 18.04) I'm trying to install libcairo2-dev but I am getting info about missing dependencies. Finally it liitks like everything is installed but there is some problem with lib naming or something. Anyone has any ideas?

> sudo apt install libcairo2-dev

The following packages have unmet dependencies:
 libcairo2-dev : Depends: libglib2.0-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

then

> sudo apt install libglib2.0-dev

The following packages have unmet dependencies:
 libglib2.0-dev : Depends: libselinux1-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

then

> sudo apt install libselinux1-dev

The following packages have unmet dependencies:
 libselinux1-dev : Depends: libpcre2-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

then

> sudo apt install libpcre2-dev

The following packages have unmet dependencies:
 libpcre2-dev : Depends: libpcre2-8-0 (= 10.34-7) but 10.34-7+ubuntu18.04.1+deb.sury.org+1 is to be installed
E: Unable to correct problems, you have held broken packages.

but finally it is ok but not ok

> sudo apt install libpcre2-8-0

libpcre2-8-0 is already the newest version (10.34-7+ubuntu18.04.1+deb.sury.org+1).

EDIT:

@N0rbert: running:

> apt-cache policy libpcre2-8-0 libpcre2-dev libselinux1-dev libglib2.0-dev

outputs:

Focal Fossa's official repository contains liblibpcre2-8-0 v10.34-7. However, you have v10.34-7+ubuntu18.04.1+deb.sury.org+1 installed which clearly seems to be from third party source. Since the output of apt-cache policy libpcre2-8-0 shows that you don't have any sources which provides the unofficial version, you can install v10.34-7 using apt. To install run,

sudo apt install libpcre2-8-0=10.34-7
