How do I install Cario 1.16.0 for WeasyPrint 51 on Ubuntu 18.04
I need Cario > 1.15.4 to get weasyprint 51 working (https://weasyprint.readthedocs.io/en/latest/install.html), but the docs seem to think it as simple as running:
sudo apt-get install build-essential python3-dev python3-pip python3-setuptools python3-wheel python3-cffi libcairo2 libpango-1.0-0 libpangocairo-1.0-0 libgdk-pixbuf2.0-0 libffi-dev shared-mime-info
...for an Ubuntu install. But this gives me:
The following packages have unmet dependencies:
libcairo2 : Depends: libc6 (>= 2.29) but 2.24-11+deb9u4 is to be installed
Depends: libfontconfig1 (>= 2.12.6) but 2.11.0-6.7+b1 is to be installed
Depends: libfreetype6 (>= 2.9.1) but 2.6.3-3.2 is to be installed
python3-cffi : Depends: python3-cffi-backend (< 1.9.1-2+c) but it is not going to be installed
Depends: python3-cffi-backend (>= 1.9.1-2) but it is not going to be installed
Depends: python3-pycparser but it is not going to be installed
python3-dev : Depends: libpython3-dev (= 3.5.3-1) but it is not going to be installed
Depends: python3.5-dev (>= 3.5.3-1~) but it is not going to be installed
python3-pip : Depends: python-pip-whl (= 9.0.1-2+deb9u1) but it is not going to be installed
python3-setuptools : Depends: python3-pkg-resources (= 33.1.1-1) but it is not going to be installed
So I tried apt -f install and then ran the command again. Everything when fine but apt list | grep libcairo2 still shows:
libcairo2/oldstable,now 1.14.8-1 amd64 [installed]
libcairo2-dev/oldstable 1.14.8-1 amd64
libcairo2-doc/oldstable 1.14.8-1 all
So I tried apt install libcairo2-dev but I get:
root@f8657d732ac8:~# apt list | grep cairo
...
libcairo2/now 1.14.8-1 amd64 [installed,local]
libcairo2-dev/now 1.14.8-1 amd64 [installed,local]
...
I also tried:
wget http://archive.ubuntu.com/ubuntu/pool/main/c/cairo/libcairo2_1.16.0-4_amd64.deb
dpkg -i libcairo2_1.16.0-4_amd64.deb
but then I get:
root@54e69efbb962:~# dpkg -i libcairo2_1.16.0-4_amd64.deb

If I run apt --fix-broken install to fix broken dependencies and run dpkg -i libcairo2_1.16.0-4_amd64.deb I get the same result.
I have also tried apt install ./libcairo2_1.16.0-4_amd64.deb and that gives me:
Reading package lists... Done

Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libcairo2 : Depends: libc6 (>= 2.29) but 2.24-11+deb9u4 is installed
Depends: libfontconfig1 (>= 2.12.6) but 2.11.0-6.7+b1 is installed
Depends: libfreetype6 (>= 2.9.1) but 2.6.3-3.2 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
Any ideas?
Solution
I tried installing the packages on a new ubuntu 18.04 docker image and it went smoothly. Below are the steps I did:
apt-get update && apt-get install -y lsb-release && apt-get clean all
apt-get install build-essential python3-dev python3-pip python3-setuptools python3-wheel python3-cffi libcairo2 libpango-1.0-0 libpangocairo-1.0-0 libgdk-pixbuf2.0-0 libffi-dev shared-mime-info
pip3 install weasyprint
I uploaded the container image on Docker Hub.
docker pull jegtugado/public:weasyprint
