当我启动 LibreOffice 时，Gnome 会显示一条通知：
“需要附加字体。应用程序正在请求附加字体。”
我尝试了所有方法来刷新字体目录的缓存，也删除了字体缓存目录并再次刷新它，但都没有解决。实际上，这只会在用户界面中产生一个问题，即页数计数和字数计数不会出现在 Writer 状态栏中。所以我看不到字数，直到我单击状态栏中的位置以显示字数窗口。我使用的是 LibreOffice 6.3，遇到了同样的问题，所以我决定升级到 7.2，但问题仍然存在。我正在使用带有 Gnome 的 Ubuntu 18.04。
当我尝试重新安装 Ubuntu-Desktop 时出现错误：
sudo apt-get install --reinstall ubuntu-desktop
