python3-dev安装时ubuntu 18.04.4我遇到以下问题
E: Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/p/python3.6/libpython3.6-dev_3.6.9-1~18.04ubuntu1_amd64.deb 404 Not Found [IP: 43.255.166.254 80]

据我观察python3.6-dev_3.6.9-1~18.04ubuntu1_amd64.deb，这些包libpython3.6-dev_3.6.9-1~18.04ubuntu1_amd64.deb不可用相反
python3.6-dev_3.6.9-1~18.04ubuntu1.1_amd64.deb，libpython3.6-dev_3.6.9-1~18.04ubuntu1.1_amd64.deb是可用的。（注意ubuntu1和ubuntu1.1的区别）
我尝试手动下载并安装python3.6-dev_3.6.9-1~18.04ubuntu1.1_amd64.deb软件包libpython3.6-dev_3.6.9-1~18.04ubuntu1.1_amd64.deb，但出现以下错误

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libpython3.6-dev : Depends: libpython3.6-stdlib (= 3.6.9-1~18.04ubuntu1.1) but 3.6.9-1~18.04ubuntu1 is to be installed
Depends: libpython3.6 (= 3.6.9-1~18.04ubuntu1.1) but 3.6.9-1~18.04ubuntu1 is to be installed
python3-dev : Depends: libpython3-dev (= 3.6.7-1~18.04) but it is not going to be installed
Depends: python3.6-dev (>= 3.6.7-1~) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).`

最后通过从 dpkg 中删除其他架构解决了这个问题
sudo apt-get remove --purge `dpkg --get-selections | awk '/arm64/{print $1}'`
sudo apt-get remove --purge `dpkg --get-selections | awk '/armhf/{print $1}'`
sudo dpkg --remove-architecture armhf
sudo dpkg --remove-architecture arm64
