来自PPA的emacs25和emacs26不能共存。

Question

我从这个PPA：https://launchpad.net/~kelleyk/+archive/ubuntu/emacs安装了C1，它与存储库中的emacs 24共存(Ubuntu16.04)。既然emacs26可以从同一个PPA中获得，我想我可以安装所有三个版本。但是，emacs26无法安装，因为它与emacs25共享一些文件，我也不能删除emacs26安装的任何文件。

我试着遵循以下建议：无法从ppa安装Emacs 24 :cassou/emacs，但是

sudo apt-get remove `apt-cache search emacs | awk '{print $1}'` --purge 

给予：

~$ sudo apt-get remove `apt-cache search emacs | awk '{print $1}'` --purge

我也尝试过sudo apt-get autoremove，没有运气。

我该怎么做？我不再坚持25版和26版共存了，我只想要一个可以工作的Ubuntu系统。

编辑:我正在插入remove和purge命令的结果。

在此之后，sudo apt-get -f install的结果与上面所示的相同。

Answer 1

正如@fkraiem所描述的，安装emacs26-common与emacs25-common冲突。以下步骤对我很有效：

注意：这将从系统中删除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
