I am trying to install libcairo2-dev in a Ubuntu 18.04.2 LTS Bionic.
I run :
$ sudo apt-get install libcairo2-de

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:
libcairo2-dev : Depends: libx11-dev but it is not going to be installed
Depends: libxrender-dev (>= 0.6) but it is not going to be installed
Depends: libxext-dev but it is not going to be installed
Depends: libxcb1-dev (>= 1.6) but it is not going to be installed
Depends: libxcb-render0-dev (>= 1.6) but it is not going to be installed
Depends: libxcb-shm0-dev but it is not going to be installed

Then I try
$ sudo apt-get autoclean

But nothing works,
My sources.list :
cat /etc/apt/sources.list

deb http://archive.ubuntu.com/ubuntu bionic-updates main restricted universe multiverse
Then I tried what guiverc and StrabagISS_Krall suggested
sudo apt-get update

In fact, I check the version of each dependency they are there with the last version.
$ apt-cache showpkg libx11-dev
Package: libx11-dev
Versions:
2:1.6.4-3ubuntu0.2 (/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_bionic-updates_main_binary-amd64_Packages)
$ apt-cache showpkg libxrender-dev
Package: libxrender-dev
Versions:
1:0.9.10-1 (/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_bionic_main_binary-amd64_Packages)
N0rbert suggested to recreate the repository list, but when I run sudo apt-get update none of the repositories fail to fetch, see above. But anyway I tried to recreate the repository list as suggest in How do I restore the default repositories? but did not work.
sudo apt updatedo you get expected results? I'd suggest doing that first, then letting your system upgrade fully, reboot and re-try (butsudo apt updateis your first response, & read messages; lack of messages is a huge clue!) – guiverc Apr 21 '20 at 06:54aptitudesolutions. Any things else just record what you tried and report back on this question, link of answer and result. – user.dz Apr 21 '20 at 12:35
