读了一点之后，我删除了 snapd 和朋友这里，这里和这里。
不过，当我使用 ie thunderbird 运行 apt search 时，它会返回与 snapd 相关的结果：
$: apt search thunderbird
Sorting... Done
Full Text Search... Done
thunderbird/noble 2:1snap1-0ubuntu3 amd64
Transitional package - thunderbird -> thunderbird snap
当我安装它时，它会通知我该软件需要 snapd：
$: apt install thunderbird
apt install thunderbird

The following information may help to resolve the situation:
The following packages have unmet dependencies:
thunderbird : PreDepends: snapd but it is not going to be installed

我确实应该看到以下内容：
$: apt install thunderbird

E: Unable to locate package thunderbird
是否可以配置 apt 使其停止在存储库中查找 snap 包？就目前情况而言，我感到困惑和恼火，因为 snap 结果使我的搜索变得混乱，我不确定包是否可用。我显然不想看到只有 snap 的包，因为我不想使用 snap。
我目前使用的是 Ubuntu 24.04 LTS。
