起初
$ xpra --version
xpra v3.0.7-r25627
然後我升級了xpra
$ sudo apt install xpra

xpra is already the newest version (3.0.8-r25889-1).
為什麼顯示xpra版本不符？
是由於 xpra 套件還是 apt 或 dpkg 造成的？
謝謝。

您已經升級了軟體包，但尚未升級軟體包，這決定了您真正使用的 Xpra 版本。
正如伊普爾所說，上游 Xpra 包將其內容分成xpra包含啟動器腳本（和配置等）的小套件和包含實作的 Python 套件。
要升級 Xpra，您需要升級所有與 Xpra 相關的軟體包：
sudo apt install xpra xpra-html5 python3-xpra
xpra套餐可以聲明對其他 Xpra 軟體包的嚴格版本依賴，這將導致它們全部升級sudo apt install xpra；但事實並非如此，這就是為什麼用戶需要確保它們全部保持同步。 （我想上游打包商假設用戶一直升級他們的所有軟體包。）
您可以刪除 Python 2 包，不再需要它：
sudo apt purge python2-xpra
