For the reason of wifi drivers, I upgraded Linux kernel to linux-generic-hwe-18.04-edge. First question is: If directly install winswitch, it said that ""The following packages have unmet dependencies: winswitch : Depends: xpra (>= 1.0) but it is not going to be installed Recommends: python-gnome2-desktop but it is not installable Recommends: python-gst0.10 but it is not installable E: Unable to correct problems, you have held broken packages. "". But I already installed python-gnome2 and python-gnome2-dev. ------------------------------------------- I installed xpra then winswitch (newest version even beta version). I can open winswitch now. When I connected a remote server successfully, I try to start applications. But then jumped out a message box who let me input the password of user ""xxx"" (my username). It just like this: --------------------------------------------- | Server Authentication | | | | Please enter the password for user 'xxx', | | connecting to tcp server 127.0.0.1:12460 | | | | [Input box] | | | | Cancel OK | --------------------------------------------- When I input the correct password of my username (the user name and password of local pc and remote pc is the same), it said: Connection Failed: disconnected before the session could b... authentication failed Then next message: Session XXXXXX failed 2020-01-25 :0.0(508x285 mm - DPI 96x96) workarea: 1845x1053 at 75x27 2020-01-25 eDP-1(309x174mm-DPI:157x157) 2020-01-25 Warning:server connection failure: 2020-01-25 disconnected before the session could be established The remote server run a ubuntu 16.04, which can be connected normally using a Windows computer and my old 16.04 desktop. I struggled to solve this but have no idea. It's kind of you, if there is any suggestion.",defect,closed,major,,Client,wontfix,,
