Hey @timanix,
Thanks for all of this - everything looks as I'd expect, and these are all reasonable virtual package versions & system versions in your conda instance... That being said, since downgrading conda did fix the initial issue, I think we can table this for the time being - but I'll keep a close eye out to see if anyone else runs into the same problem on linux, and please reach back out and let me know if you run into anything else unexpected!
