mesa-common-dev：未滿足的依賴項

我正在嘗試在 Ubuntu LTS 上安裝mesa-common-dev ：

sudo apt-get install mesa-common-dev

但是，系統返回：

    mesa-common-dev : Depends: libgl-dev but it is not going to be installed
                      Depends: libglx-dev but it is not going to be installed
                      Depends: libglx-dev but it is not going to be installed

成功！！我加：

deb http://archive.ubuntu.com/ubuntu focus-updates 主要受限宇宙多元宇宙

在source.list文件中。

謝謝你幫助我

focal-updates您的 , 中缺少/etc/apt/sources.list以糾正問題：

echo "deb http://archive.ubuntu.com/ubuntu focal-updates main restricted  universe multiverse" |\
sudo tee -a /etc/apt/sources.list
sudo apt update
sudo apt install mesa-common-dev
