如何在 Debian 11 上将 TigerVNC 升级到 1.12？

  • 772

我有一台运行 Debian 11 的开发机器，它目前是我们设备主机的标准环境。我使用 VNC（TigerVNC 服务器）从我的工作计算机远程访问它。问题是 Debian 11 附带的 TigerVNC 有一个非常烦人的错误，会干扰我的工作。

该错误早已修复，但是没有官方的反向移植，并且据我所知，Debian 11 的反向移植已经停止。

因此，解决问题的唯一方法是手动反向移植 TigerVNC。

我尝试遵循Faheem Mitha 的反向移植指南，因为它似乎是最适合这种情况的方法，需要特定于 Debian 的配置和构建。我设法进入第 4 步：

 debuild -uc -us

The following information may help to resolve the situation:

                      Depends: x11proto-dev (>= 2021.5) but 2020.1-1 is to be installed

E: Unable to correct problems, you have held broken packages.

但是，我不明白指南中应该如何处理未满足的依赖项。我应该降低 debian/control 中所需的版本吗？特别是，我该如何处理标记为可卸载的 libxcvt-dev？

    抱歉，让您陷入反向移植的泥潭 — 在类似情况下，这通常是最好的方法，但对于 TigerVNC 来说，它却毫无用处。将当前的 TigerVNC 12 软件包反向移植到 Debian 11 会相当复杂，特别是因为它与特定版本的 X.Org 软件包绑定在一起。

    鉴于您关心的错误的修复很简单：

    diff --git a/common/rfb/VNCServerST.cxx b/common/rfb/VNCServerST.cxx
index fe0608572f..ae51a61b11 100644
--- a/common/rfb/VNCServerST.cxx
+++ b/common/rfb/VNCServerST.cxx
@@ -169,7 +169,7 @@ void VNCServerST::removeSocket(network::Socket* sock) {
       if (pointerClient == *ci)
         pointerClient = NULL;
       if (clipboardClient == *ci)
-        clipboardClient = NULL;
+        handleClipboardAnnounce(*ci, false);
       clipboardRequestors.remove(*ci);
 
       // - Delete the per-Socket resources

    添加该补丁后，重建 Debian 11 TigerVNC 包变得更加容易。

    要做到这一点：

    • 下载TigerVNC的Debian 11源码包：

      apt source tigervnc/oldstable

    • 下载补丁：

      cd tigervnc-1.11.0+dfsg
curl https://github.com/TigerVNC/tigervnc/commit/49122f6dccd836f0a4618247895fd4c5b8db7af0.patch > debian/patches/desktop-clipboard.patch

    • 将其添加到应用于软件包的补丁列表中：

      echo desktop-clipboard.patch >> debian/patches/series

    • 应用它：

      quilt push

    • 添加变更日志条目：

      dch --nmu "Apply upstream fix for clipboard handling."
dch -r ignored

    • 构建包：

      debuild -us -uc
