问题已解决
是数据源的debian版本的问题

然后我查了一下xorg-video-abi-23
显示有
dep: xorg-video-abi-23
本虚包由这些包填实: xserver-xorg-core, xserver-xorg-core-udeb
在下载xserver-xorg-core-udeb 时
pi@raspberrypi:~ $ sudo apt-get install xserver-xorg-core-udeb
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package xserver-xorg-core-udeb
请问这样要怎么办呢?

@Spoony

按照链接中所给步骤操作,下载xorgxrdp时显示问题为未下载xorg
下载xorg后再下载xorgxrdp仍然不成功,且远程连接问题如常
