Regular ContributorHi Matthew,
It seems like it is driver related on Linux or software on the host machine that is conflicting with with USB Blaster. Can you try to install the blaster drive again on linux by following the guide below?

Also, can you try with USB Blaster II and have the TCK frequency set to 6MHz?
Thank You.
New ContributorIt's been a while since I looked at this, but your timing is good as I just picked it up again a couple of days ago.
There is no driver for the USB Blaster on Linux, however I can confirm that this isn't a permissions issue - I have full write access to the ports.
The dev boards I'm using have an integrated USB Blaster on them, and so I am not using an external programmer. That said, if you are willing to send me a Blaster II I can test it. I am not going to purchase a $250 programmer as a random test.
One other note - it appears that this is tied to changes in behavior in the Quartus programmer itself. I have installed an older release of Quartus (15.1 in particular), and programming the DE2i-150 and DE10-lite boards using that appears to work much more reliably. I still intend to do the compilation on 19.1, but I can fire up the older programmer and hopefully script the whole process.
