我猜这个问题之前已经被回答过。如果是这样，请指出该主题的链接
我在 Zareason 关门之前购买了一套计算机系统。
apt-get update它最初安装了 Debian Buster，并继续使用和更新到测试/不稳定版本apt-get upgrade
即使系统显示 trixie 已安装，sources.list 中的所有条目都使用 buster：
$ cat /etc/issue
Debian GNU/Linux trixie/sid \n \l
我的问题：
我宁愿保留它使用稳定版本，直到下一个版本移至稳定版本；我怎样才能做到这一点
是否可以降级到稳定版 12.2。或者这太有问题了。
再次向您道歉。希望我已经回答了那些试图提供帮助的人的问题。
/etc/apt/sources.list.d 中的两个文件。我不确定为什么同一个应用程序有两个。接下来是以下内容。
$ cat wire-desktop.list
deb [arch=amd64] https://wire-app.wire.com/linux/debian stable main
$ cat wire-desktop.list.save
deb [arch=amd64] https://wire-app.wire.com/linux/debian stable main
source.list 的输出

最后，我不再使用 NVidea 的非固件。正如你所看到的，这些行被注释掉了
