Emacs 在 Ubuntu 20.04 上安装失败

Question

我想简单地做：

sudo apt install emacs

在 Ubuntu 20.04 上。

结果是，安装时出现错误emacsen-common，emacs-gtk最终是所有 emacs 的依赖项。我看到的错误是：

Setting up emacs-gtk (1:26.3+1-1ubuntu2) ...
Install emacsen-common for emacs
emacsen-common: Handling install of emacsen flavor emacs
emacs: error while loading shared libraries: libotf.so.0: cannot open shared object file: No such file or directory
ERROR: install script from emacsen-common package failed
dpkg: error processing package emacs-gtk (--configure):
 installed emacs-gtk package post-installation script subprocess returned error exit status 1
dpkg: dependency problems prevent configuration of emacs:
 emacs depends on emacs-gtk (>= 1:26.3) | emacs-lucid (>= 1:26.3) | emacs-nox (>= 1:26.3); however:
  Package emacs-gtk is not configured yet.
  Package emacs-lucid is not installed.
  Package emacs-nox is not installed.

dpkg: error processing package emacs (--configure):
 dependency problems - leaving unconfigured
No apport report written because the error message indicates its a followup error from a previous failure.
Errors were encountered while processing:
 emacs-gtk
 emacs
E: Sub-process /usr/bin/dpkg returned an error code (1)

我希望得到一些关于如何解决这个问题的想法。

Answer 1

为了解决这个问题，我首先做了sudo apt purge emacs。

然后我重新安装了 libotf0 和 libm17n-0，使用：

sudo apt install --reinstall libotf0 libm17n-0

之后，sudo apt install emacs按预期工作。

Answer 2

也可以通过另一种方式做到这一点：通过snap store使用 snap 包
