내 로컬 xpra 클라이언트는
t@ocean:/u/l/jvm$ xpra --version
xpra v3.0.7-r25627
원격 xpra(서버 또는 클라이언트 또는 둘 다)는 다음과 같습니다.
t@ocean:/u/l/jvm$ ssh t@onion
t@onion:~$ xpra --version
xpra v3.0.8-r25889
t@onion:~$ logout
Connection to onion closed.
로컬과 원격 모두 Lubuntu 18.04를 실행하고 있습니다.
감사해요.
답변1
로컬 xpra 버전을 원격 xpra 버전과 동일하게 업그레이드한 후,
sudo apt install xpra
문제가 사라졌습니다.
