Emacs 在 WSL2、Ubuntu 上因分段错误而崩溃

Question

昨天还安全运行的Emacs，升级Ubuntu后，无法启动，出现段错误。

环境：

• Windows 10
• WSL2
• Ubuntu 22.04.3 LTS
• 2022-05-31 的 Emacs 28.1（内部版本 1.x86_64-pc-linux-gnu、GTK+ 版本 3.24.20、cairo 版本 1.16.0）

emacs -Q

无法启动并出现相同的错误。

emacs -nw

可以启动。

xeyes

可以启动，所以我认为 X Window 工作得很好。

请给我任何建议。

我附上以下段错误的日志：

Answer 1

我升级了 WSL，问题就消失了。

1. 启动cmd.exe
2. 调用

   wsl --update

仅此而已。
