Hi all, I can not install xpra on Ubuntu 17.10 Artful AArdvark because I get the following:

W: GPG error: http://winswitch.org artful Release: The following signatures were invalid: EXPKEYSIG 18ADB31CF18AD6BB Antoine Martin <[email protected]>
E: The repository 'http://winswitch.org artful Release' is not signed.

I followed instructions on: ​https://winswitch.org/downloads/debian-repository.html?dist_select=artfulbeta

and on: https://winswitch.org/trac/ticket/304

Steps to reproduce:

apt-get install curl
curl https://winswitch.org/gpg.asc | apt-key add -

and

apt-get install dirmngr
apt-key adv --fetch-keys https://xpra.org/gpg.asc

both get me the above message; while

apt-key adv --keyserver keys.gnupg.net --recv-keys F18AD6BB

results in a connection timeout.

Please advice, Thanks

I have an Italian keyboard. Some keys (notably ',?', '{', '}', '#' and '@') are only available via 'AltGr?' escape. All these keys do not appear to work.

Setup:

• Server: Linux Wheezy_amd64
  • LANG=en_US.UTF-8
• Client: Windows Seven x64
  • Italian setup
• Test program: eclipse 3.8.0
• Winswitch was installed today following indication on web site.
• All software installed is standard and up-to-date.
• All other keys are correctly interpreted as Italian KBD in spite of client/server language mismatch (e.g.: all accented letters are correct).

In trying to get a WinSwitch/xpra server on Ubuntu to work with a WinSwitch/xpra client on OSX, I had to fight with xmodmap a bit (need to use Alt for Eclipse, emacs, etc.). I found the check for running X server not to be quite right. The following diff is for an older version of winswitch/client/client_base.py (I can't use the latest due to ​https://xpra.org/trac/ticket/92), so the lines aren't current but their content hasn't changed.

The first change fixes the search of lines for "org.x.startx". In the old form, line.find returns -1 for any line without a match, triggering on the very first line ("PID Status Label"). Python documentation states a preference for "substring in string", when the position of substring in string is not needed. If you want to insist on "org.x.startx" at the very end of the line, the test could be: if line.endswith("org.x.startx"):

The second change corrects the check for a process that's running now ("0" in parts[1] appears to indicate that the process has terminated and returned 0). Checking that parts[0] is NOT "-" is a valid check for a running process, as well. The man pages are a bit vague.

The changes below work on my MacBookPros at home and at work with 10.5 and 10.6:

<                                       if line.find("org.x.startx$"):
---
>                                       if "org.x.startx" in line:
436c436
<                                                       started = parts[1]=="0"
---
>                                                       started = parts[1]=="-"

I hope this helps. -Alexey
