Ubuntu 安装vlc之后无法正常打开，命令行输入`vlc`，显示如下错误信息：
|
|||
|
|
|
|||
|
|
```sh
|
|||
|
|
> vlc
|
|||
|
|

解决方案如下：
|
|||
|
|
|
|||
|
|
```sh
|
|||
|
|
sudo rm /var/cache/fontconfig/*
|
|||
|
|
rm ~/.cache/fontconfig/*
|
|||
|
|
fc-cache -r
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
上述命令，执行完之后，再次打开vlc，需要等待一段时间，然后就可以正常使用。
|
|||
|
|
|
|||
|
|
第二种解决方案是使用 `sudo apt install vlc` 安装，不要用snap。先卸载snap的vlc，再安装，就可以正常打开了。

具体是什么原因不是很清楚，本地网络不通也会出现这个错误。
