我似乎安装了三个版本的 LibreOffice。我偶尔将数据库用于邮件合并，所以我怀疑 7.0 版本是我想要保留的版本。是否有一个简短的apt-get命令可以在不破坏任何内容的情况下删除另外两个？

$ libreoffice  [\t for autocomplete]
libreoffice     libreoffice6.4  libreoffice7.0  
`
$ which libreoffice
/usr/bin/libreoffice

$ ls -las /usr/bin/libreoffice
0 lrwxrwxrwx 1 root root 34 Nov  2 08:44 /usr/bin/libreoffice -> ../lib/libreoffice/program/soffice

$ which libreoffice7.0
/usr/local/bin/libreoffice7.0

$ ls -las /usr/local/bin/libreoffice7.0
0 lrwxrwxrwx 1 root root 35 Sep 30 21:29 /usr/local/bin/libreoffice7.0 -> /opt/libreoffice7.0/program/soffice

$ which libreoffice6.4
/usr/local/bin/libreoffice6.4

$ ls -las /usr/local/bin/libreoffice6.4

我有一个 H2 Zoom 麦克风，直到 20.10 之前我都将它用作 USB 麦克风。它不再起作用了。

当我用 打开它时alsamixer，它告诉我“此声音设备没有任何控件”。

的内容/proc/asound/H2是

id  pcm0c  pcm0p  stream0  usbbus  usbid  usbmixer

的内容stream0是：

ALSA 是否放弃了对这款麦克风的支持？有没有办法获得和启用旧版支持？还是有其他问题？

更新：我将它插入到另一台运行 Ubuntu 工作室的计算机中。Alsa 还说它没有控件，但它显示在设置应用程序中，我可以使用它。它运行的是 Ubuntu 20.04 LTS，而不能运行的是 20.10。20.10 缺少什么，我该如何解决？

通过 gui 打开 Chromium 已停止工作。当我通过命令行尝试时，我得到：

$ /snap/bin/chromium
[15738:15738:1026/130054.950616:ERROR:browser_main_loop.cc(1426)] Unable to open X display.

我在 Wayland 上运行 Gnome 3。我已经安装了 xwayland。

更新：这个问题似乎影响了我所有安装的快照。

任何建议表示赞赏。
