最近我迁移了 Kubuntu 和 KDE，并删除了与 Gnome 相关的所有内容（当然有一些例外）。我读了一些资料，了解到 Kubuntu 有自己的存储库。所以，我想知道的是我必须以何种方式更改我的存储库列表。我的意思是我的列表中的哪些部分应该丢弃，哪些部分应该保留。这是我的 sources.list：
# deb cdrom:[Ubuntu 12.04 LTS _Precise Pangolin_ - Release amd64 (20120425)]/ dists/precise/main/binary-i386/
# deb cdrom:[Ubuntu 12.04 LTS _Precise Pangolin_ - Release amd64 (20120425)]/ dists/precise/restricted/binary-i386/
# deb cdrom:[Ubuntu 12.04 LTS _Precise Pangolin_ - Release amd64 (20120425)]/ precise main restricted

答案1
Kubuntu 有相同的官方存储库与常规 Ubuntu 一样。无需更改。如果您想添加不受支持的“前沿” KDE 软件包的 PPA，则这些是额外的，风险由您自行承担。
答案2
是的，因为韋萊说，你不应该删除任何存储库，并且 Kubuntu 具有与 Ubuntu 相同的核心包，但安装了不同的包。
然而，我在新安装的 Kubuntu 中做的第一件事就是添加ppa:kubuntu-ppa/ppa，因为官方存储库不会推送新的 KDE 版本...我也向您推荐它；我从来没有遇到过问题，因为新的 KDE 版本也在那里得到了适当的测试。
ppa:kubuntu-ppa/backports当 Ubuntu 发布了新版本而您使用的是旧版本且不想升级时，可能也值得添加。此存储库将继续获取新的 KDE 版本，而旧.../ppa版本将变得安静并转向下一个版本的 Ubuntu。
