Apt
在 Ubuntu 16.04 上安裝 Emacs25 軟體包時出錯
我正在嘗試在 Ubuntu 16.04 上安裝 Emacs25 軟體包以及 Emacs 24 和 Emacs-snapshot（目前為 Emacs 27.0.50）。
我執行了以下命令
sudo add-apt-repository ppa:kelleyk/emacs sudo apt-get update之後我跑了
sudo apt install emacs25在此期間我得到這個

您可以使用您引用的輸出中的以下錯誤消息來解決此問題：
Unpacking emacs25-common (92792-c3ff671-emacs-25.2~ubuntu16.04.1) ... dpkg: error processing archive /var/cache/apt/archives/emacs25-common_92792-c3ff671-emacs-25.2~ubuntu16.04.1_all.deb (--unpack): trying to overwrite '/usr/share/emacs/site-lisp/subdirs.el', which is also in package emacs-snapshot-common 20190326:96618-9a6cba2~ubuntu16.04.1安裝失敗，因為兩者
emacs-snapshot-common都emacs25-common包含/usr/share/emacs/site-lisp/subdirs.el.有很多方法可以解決這個問題，但值得考慮的是，儘管 Emacs 包的名稱中包含版本號，但它們並非設計為可共同安裝的。（事實上，從 Debian 10 和 Ubuntu 18.10 開始，這些軟體包的名稱中不再包含版本號。）
解決這個問題的最乾淨的方法是轉移一個包的文件副本；例如，要保留
emacs25的副本：sudo dpkg-divert --package emacs25 --divert /usr/share/emacs/site-lisp/subdirs.el.moved --rename /usr/share/emacs/site-lisp/subdirs.el（語法相當違反直覺；有關詳細資訊，請參見手冊
dpkg-divert頁）。subdirs.el這會將其他包提供的任何版本重命名emacs25為subdirs.el.moved.
