Some users have been unable to connect to the REPL from Debian Linux machines. This problem may be related to #1642 and #1617.

See @mlupo commenting in https://forums.adafruit.com/viewtopic.php?f=60&t=149291#p737722. MTO in discord #help-with-circuitpython 2019-03-25 also had trouble with two different Debian 9 machines, a Udoo Ultra (x64) running Debian 9.7, and an older laptop running 9.something. MTO did not have an issue with an Odroid HC2 running 9.7.

I installed Debian 9.8 on an external hard drive, and then booted it up on three machines:

  1. Dell Optiplex 7010 desktop
  2. Dell Latitude 4310 laptop
  3. Lenovo 110S laptop

In all cases, I was able to connect a PyPortal running 4.0.0 beta.5, and then connect to the REPL via /dev/ttyACM0. So I'm not sure what's going on with the other machines. I've asked @mto on discord to update to 9.8 to see if that fixes things.

On the Odroid, uname -a reports

On the Udoo:

I don't see a change in behaviour: The filesystem doesn't mount, the serial port doesn't respond. Here's dmesg output:

On the laptop: A Lenovo Thinkpad X1 Carbon (4th gen) also running debian 9.8
The kernel was already up to date. Dist-upgrade only updated a few libs.

@emteeoh Could you try this build on your pyportal, on the various hosts that don't work?

https://adafruit-circuit-python.s3.amazonaws.com/bin/pyportal/en_US/adafruit-circuitpython-pyportal-en_US-20190328-c6e3b17.uf2. This is the build from this PR: #1721.

Wahoo! CIRCUITPY mounts, and I can talk to it on the console!
It is seeing some garbage on the console somehow, causing errors, but I'm pretty sure that's host side. Once I'm on the console and hit CTRL-D it runs normally.

Could we get a build for the neoTrellis too?

Just look for the same commit number c6e3b17 (or later) on the Amazon S3 site above for other builds.

The garbage you are seeing could be due to modemmanager running on your host (especially if you se "AT" in the strings. Just uninstall it -- it doesn't have much purpose nowadays.

Thanks!
The neoTrellis works too with c6e3b17!

removing modemmanager fixed the garbage, too.
