最后我无法从 repo 安装许多程序。“file:///media..”和“file:/media...”之间没有区别
我该如何继续？
答案1
代替file:///path/to/repo：
deb "file:///media/miguel/My Passport/xenial-repo" xenial main restricted universe multiverse
...
在你的情况下，它应该只是file:/path/to/repo：
deb "file:/media/miguel/My Passport/xenial-repo" xenial main restricted universe multiverse
deb "file:/media/miguel/My Passport/xenial-repo" xenial-backports main restricted universe multiverse
deb "file:/media/miguel/My Passport/xenial-repo" xenial-updates main restricted universe multiverse
deb "file:/media/miguel/My Passport/xenial-repo" xenial-proposed main restricted universe multiverse
deb "file:/media/miguel/My Passport/xenial-repo" xenial-security main restricted universe multiverse
