Debian Sid：将单个软件包降级到“以前的版本”

  • 772

我很高兴地运行着一个最先进的 Debian Sid 工作站。

不幸的是，我发生了“上游回归”（network-manager-vpnc 破坏了 1.2.7 -> 1.2.8）

因此，我需要“降级”到以前的版本。

我知道我应该能够做到这一点：

sudo apt install network-manager-vpnc=1.2.7

但这似乎对 Sid 不起作用：

sudo apt policy network-manager-vpnc
network-manager-vpnc:
  Installed: 1.2.8-3
  Candidate: 1.2.8-3
  Version table:
 *** 1.2.8-3 500
        500 http://deb.debian.org/debian sid/main amd64 Packages
        100 /var/lib/dpkg/status

这意味着只有一个版本可用，因此错误不足为奇：

sudo apt install network-manager-vpnc=1.2.7
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package network-manager-vpnc is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Version '1.2.7' for 'network-manager-vpnc' was not found

我能做些什么？

更新：正如@Stephen-Kitt 正确指出的那样，“以前的版本”（1.2.7）从未上传到 Debian 档案库，所以“解决方案”是降级到 1.2.6-3。

进入工作系统的程序（对我来说）是：

非常感谢@Stephen

    如果您使用的是 Debian，我怀疑旧版本是 1.2.7，因为它从未上传到档案中。请注意，对于apt's=语法，您需要指定完整的包版本，例如“1.2.8-3”。

    无论如何，您可以在 snapshot.debian.org 上找到过去 15 年上传到档案的软件包的所有版本；这包括network-manager-vpnc. 在那里下载适当的软件包，安装它（使用dpkg -i），然后暂停它（apt-mark hold network-manager-vpnc），这样它就不会再次升级。

    您可以apt为特定快照配置源；有关详细信息，请参阅Debian 10：升级到特定的次要版本 (10.10)。您可能还会发现为什么以前版本的 Debian 软件包会在软件包存储库中消失？（与版本控制的系统配置高度相关）相关。

    还请提交一个错误（reportbug network-manager-vpnc），以便其他人可以了解回归并希望它可以修复。
