Python error and issue after updating to Bullseye

[mannp]

Hi there

I thought I updated to 0.56 yestersday and then upgraded to debian 11.

The upgrade seemed to go well and everything appeared to be working, but this morning my box is down.

I tried to upgrade again, but am getting this error... it appears I am not on 0.56 or the update script is not getting 0.56 with Debian 11 maybe?

My admin gateway is 502 but the base domain displays the correct html page.

Any help would be appreciated :) thanks in advance

Edit: Tried purging python and pip and rerunning the install script but nothing I have tried works...same error.

Google is full of reports of the error but, a convoluted mess of answers, that either don't work or are not appropriate here.

Trying to reproduce the issue:

• Deploy VM with Debian 10
• Install v56.0
• Upgrade to Debian 11
• Re-run the setup

Not exactly sure where this could fail, I'll get back to you if I find anything interesting.

Update - I was able to reproduce the issue. Band-aid solution is to run the following command:

sudo rm -rf /usr/local/lib/mailinabox/env

Then re-run the setup as usual. This will force the setup to re-create the management environment from scratch instead of using old python versions.

Or... update again, because it should be fixed now :)

Glad you were able to reproduce and fix, thank you.

I was so close to removing the env, based on suggestions around the web, but wasn't sure of the consequences, lol.

Now I do and see your change :)

Thanks again.

elif [ "$(cat $venv/.oscode)" != $(get_os_code) ]; then
	echo "Existing management environment is from an earlier version of the OS you're running."
	echo "Re-creating Python environment..."
	rm -rf $venv
	hide_output virtualenv -ppython3 $venv
