Hello David,

I personally compiled, packaged into .deb files, and installed the resulting Fldigi 4.1.23 .deb package on Oct 10, 2022:
   --
   $ grep fldigi /var/log/dpkg.log.1
  
   2022-10-14 09:46:04 status installed fldigi:amd64 4.1.23-1
   --

Since then, I have installed 311 different packages as part of the regular patching of Ubuntu 20.04:
   --
   $ grep -c "status installed" /var/log/dpkg.log
   168

   $ grep -c "status installed" /var/log/dpkg.log.1.modified
   143
   --


I can see where your thought process is going here but no, I did not test the operation of Fldigi (and all my other amateur radio program) after every OS update cycle.

As an experiment, I disabled OSS support but it seems there isn't a way to disable portaudio (--without-portaudio doesn't work) .  Regardless, this didn't help and the same problem persists.  To add to the debugging, I tried running via gdb but that didn't provide much additional detail:

I again deleted the fldigi_def.xml file and then ran fldgi via gdb.  All the same gdb output was shown as above but this time the configuration wizard opened up.  As I filled it out, I then saw the following not useful output on the gdb window:

What have you installed or updated since Fldigi last ran correctly?

Which version of FLRig you running,

 

I see similar start-up failures since upgrading FLRig from 1.4.4 to 1.4.5

 

With FLRig not running I can start FLDigi, but as soon as I start FLRig then FLDigi crashes

 

Got a few updates to do to FLRig and FLDigi to bring them both to latest and greatest (only a few minor versions behind) but not sure it will help

Hello Everyone,

I have an interesting new(ish) problem with Fldigi 4.1.23 on Ubuntu 20.04 where it won't start up after the first time configuration.  If I try to start Fldigi from the command line, I will see the following on the console but I'll never see the Fldigi GUI window open and it's then just hung:
--

What's strange is if I delete the $USER/fldigi_def.xml file, start Fldigi, I will see the same above text but now I'll see the expected Fldigi configuration GUI window.  Once I configure the various fields and for the sound parameter, use PulseAudio, the main Fldigi DOES open, the waterfall starts to show correctly, and I start seeing decodes as expected.  If I shutdown Fldigi and try to restart it, the program fails to start with the same above CLI text.  In troubleshooting this, if I run Fldigi under strace, I see the following at the end and then it just stops printing anything else until I control-c the process:
