Hello everyone, I was wondering if anyone might have any ideas about this situation. Currently I have this setup:
Ubuntu 18.04 client running Firefox 72.0.1 connecting to Guacamole 1.1.0 docker container, serving out an RDP connection to a container running Mate on Ubuntu 18.04 through xrdp 0.9.5-2 Copy-paste works fine most of the time, with ctrl-c copying something inside the target container and having it immediately available on the client system clipboard to paste. Then something happens to alter this behavior that I've been unable to identify, and it stops working. But in troubleshooting the problem I discovered that it still works if I hit ctrl-c 3 times. If I hit ctrl-c once, the copied text is available inside the Mate desktop environment but not outside guacamole. Ctrl-c twice, same situation. Ctrl-c 3 times, and now it's available back in the Ubuntu client! This is pretty repeatable in my production environment, but in my development environment I still haven't gotten this failure state to happen in the first place. Anyhow, any thoughts on what to check or how to debug this issue? The usual process of restarting services and clearing caches/cookies doesn't seem to fix this situation, either, at least nothing I've been able to do with regularity. Many thanks, Brian
