【问题描述】：
我需要 Cario > 1.15.4 才能使 weasyprint 51 工作 (https://weasyprint.readthedocs.io/en/latest/install.html)，但文档似乎认为它就像运行一样简单：
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
...对于 Ubuntu 安装。但这给了我：
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
所以我尝试了apt -f install，然后再次运行该命令。一切正常，但 apt list | grep libcairo2 仍然显示：
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
所以我尝试了apt install libcairo2-dev，但我得到了：
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]
...
我也试过了：
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
然后我得到：
root@54e69efbb962:~# dpkg -i libcairo2_1.16.0-4_amd64.deb

如果我运行 apt --fix-broken install 来修复损坏的依赖项并运行 dpkg -i libcairo2_1.16.0-4_amd64.deb 我会得到相同的结果。
我也试过apt install ./libcairo2_1.16.0-4_amd64.deb 这给了我：
Reading package lists... Done
Building dependency tree
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).
有什么想法吗？
