我在 Ubuntu 20.04 上遇到了 snap 商店和 snap 软件包的问题。我的问题始于我尝试安装 VLC 媒体播放器时，我在此问题中详细说明了这一点： 帖子链接
我尝试使用 snap remove 和 snap install 命令删除并重新安装 snap store。之后，我的 snap store 就坏了，无法显示任何字符。请参见下面的屏幕截图：
当我尝试在终端中打开它时，收到以下错误消息：
bobi@bobi:~$ snap-store

除此之外，当我在终端中安装 GIMP 的 snap 版本时，它在启动时也无法加载任何字符，并且一旦加载就会崩溃。请参阅此处的加载屏幕故障：
错误信息如下：

该怎么办？Flathub 和“旧”deb 版本的 Gimp 和 Vlc 运行良好。我想我现在需要坚持使用这些。

Béné 回答了问题！谢谢！
以下解决方案几乎对我有用这个帖子！
但是，上面帖子中的第二个命令给了我一个错误消息。我对其进行了一些修改，因此以下解决方案对我有用，并且在系统重启后仍然有效。：
sudo find /usr/share/fonts -type f -exec sudo chmod 644 {} \;
sudo fc-cache -r -v
