我已经emacs25从这个 PPA 安装了：https://launchpad.net/~kelleyk/+archive/ubuntu/emacs，它与来自存储库 (Ubuntu 16.04) 的 emacs 24 共存良好。现在可emacs26从同一 PPA 获得，我想我可以安装所有三个版本。但是emacs26无法安装，因为它与 共享一些文件emacs25，并且我无法删除与 一起安装的任何文件emacs26。
我尝试遵循以下建议：无法从 ppa:cassou/emacs 安装 Emacs 24， 但

此后的结果sudo apt-get -f install与上面显示的相同。
答案1
两个软件包emacs26和emacs26-el具有未满足的依赖项emacs26-common。在这种情况下，Apt 建议运行apt-get -f install以安装缺少的依赖项，但emacs26-common由于与当前安装的 冲突而安装失败emacs25-common。因此，必须先删除emacs26和emacs26-el( apt remove emacs26 emacs26-el) 以使 Apt 恢复正常状态，然后（可能）删除emacs25和 所有相关软件包，然后再安装emacs26。
答案2
正如@fkraiem所述，安装emacs26-common与发生冲突emacs25-common。以下步骤对我来说很有效：
注意：这会删除来自您系统的 Emacs25。
sudo apt purge emacs26
sudo apt install -f
sudo apt purge emacs25
sudo apt autoclean
sudo apt autoremove
sudo apt update
sudo apt install emacs26
