pop-os 21.04 ,每次我尝试使用 apt Upgrade 或 update 执行某些操作时,我都会收到此错误
E: Failed to fetch http://ppa.launchpad.net/system76/pop/ubuntu/pool/main/m/mesa/mesa-vulkan-drivers_21.2.1-2ubuntu1pop0%7e1631200248%7e21.04%7e4d5cd49_i386.deb Cannot initiate the connection to ppa.launchpad.net:80 (2001:67c:1560:8008::19). - connect (101: Network is unreachable)

您可以暂时禁用此功能ppa:system76/pop
:
sudo add-apt-repository -r ppa:system76/pop
sudo apt update && sudo apt upgrade
或者您可以手动删除 system76 存储库:
sudo rm /etc/apt/sources.list.d/system76-pop-*.list
sudo apt update && sudo apt upgrade
