Ignore the messages, they appear every time quisk is started. A short explanation is that it checks for stuff that doesn't exist ... we call it "Just Noise" generated by the program.
What versions of quisk and Ubuntu? You mention an old Ubuntu, trouble with that is not only the OS but applications develop at pace so that old and new can become incompatible.
In your case it seems there isn't a compatibility problem.
Newer versions of quisk use the CONFIG tab rather than the old ~/quisk_conf.py file. These later versions write and use a ~/quisk_settings.json file.
If the bands are not switching it suggests that a fixed frequency Softrock may be configured.

Well, it seems that I managed to get the SDR recognized in Ubuntu, but that's about it. I followed the instructions to the letter posted here:
Like with this gentleman, however, I am getting very similar error messages like he does at the bottom of his page:

I can start Quisk, hear CW, but that's about it. I do get visual graphs and when I try and switch bands, it does sound like it's changing but no matter what frequency I try and change to in Quisk, everything stays the same and I hear the same CW.
I was really hoping to get this working on my Ubuntu system. I lack a traditional shortwave receiver at present, and I am in the process of trying to get a 20 meter QRP transceiver working, but I need to at least hear it while I'm troubleshooting which was why I had hope to get the SDR working in Ubuntu. If I can't, I'll have to put one of my unused desktops into action and install it all on XP. Just hoped I would have to as I'm very limited on space at the current time.
Any thoughts on helping me troubleshoot this would be welcome. N8MDP, although getting similar error messages as I did, said he solved them but he didn't share how. Thanks in advance for your help.
