I freshly installed ubuntu 18.04 in a new computer (with win10 as dual system). 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.

Hi!

Xpra itself works fine, but using winswitch does not: "You have requested an xpra session but this server does not support it"

When running the server from the CLI I get the following message:

[EE] 2020/29/04 19:07:38.816622 WinSwitchServer.assign_virt_utils() failed to load xpra, make sure it is installed: No module named xpra.dotxpra

There is a very old ticket with the same issue (#219). According to that i tried to link /usr/lib/xpra to a lot of locations without any effort.

If you need more input please let me know!

If an NX session does not have an actor and it is still connected somewhere (this should not happen... but it does), we should wait a bit then force the nxagent to disconnect (send kill -1)
