起初
$ xpra --version
xpra v3.0.7-r25627
然后我升级了xpra
$ sudo apt install xpra

xpra is already the newest version (3.0.8-r25889-1).
为什么显示xpra版本不匹配？
是由于 xpra 包还是 apt 或 dpkg 造成的？
谢谢。

您已经升级了软件包，但尚未升级软件包，这决定了您真正使用的 Xpra 版本。
正如伊普尔所说，上游 Xpra 包将其内容分为xpra包含启动器脚本（和配置等）的小包和包含实现的 Python 包。
要升级 Xpra，您需要升级所有与 Xpra 相关的软件包：
sudo apt install xpra xpra-html5 python3-xpra
套餐xpra可以声明对其他 Xpra 软件包的严格版本依赖，这将导致它们全部使用sudo apt install xpra;进行升级。但事实并非如此，这就是为什么用户需要确保它们全部保持同步。 （我想上游打包商假设用户一直升级他们的所有软件包。）
您可以删除 Python 2 包，不再需要它：
sudo apt purge python2-xpra
