Ubuntu 20.04 issues

Moved from Debian to Ubuntu 20.04 and now I can't get the printers to detect correctly.

Pretty much copied everything from Debian to Ubuntu. As for Octoprint I just backed up the config and restored on new box.

Don't do full auto-detection.

Your printer is at ttyACM0.

Select that, and if you know the baud rate, set that as well.

(As always) If you are installing on an Linux distro, I wrote scripts that will assist in the setup: OctoPrint.org - Download & Setup OctoPrint

so I was able to getting it working by removing "SNAP"

Kept seeing - Nov 23 03:27:53 print-01 snapd[855]: hotplug.go:200: hotplug device add event ignored, enable experimental.hotplug

sudo apt remove snapd -y --purge -- > And now they work fine...

tried static and still didn't work....

looked at two other brand new installs of 22.04 and SNAP was there and the hotplug is doing something odd with the USB ports kicking off that error. Uninstalled with "apt remove snapd -y --purge" and everything works fine.

Will keep this up here in case anyone else runs into the issue on Ubuntu 22.04.

I can say the snap install is not the way to go. I've also read you may need to disable the brittle service.

get rid of it with sudo apt remove brltty

I think the install script handles that for you too.

SNAP is always present on Ubuntu, but I just ran through a 22.04 server install on a VM and snap hotplugging in no way impacted the ability to recognize the serial port.

I didn't install via SNAP... To Paukstelis it looks like SNAP is installed by default in Ubuntu 22.04.

I used

cd /home/octoprint
virtualenv --python=python3 venv
source venv/bin/activate
pip install pip --upgrade
pip install https://get.octoprint.org/latest

Then to test it -> /home/octoprint/venv/bin/octoprint serve

When on Debian 11 I didn't have a single issue and those were running on a couple of HP mini's with i5 CPU's.

Only reason I moved from the Debian 11 was because I got a few new boxes for a killer deal, but they have Intel 12th Generation CPU (Core i7-12700) and Debian is having issues with the new CPU and chipset. Both HP and Lenovo list Ubuntu 22.04 as supported OS so that's why I went with it.

On side note I have a few other things running on these boxes like DNS, PIHole, and Docker so the bigger CPU is helping a lot!.
