Script it doesn't work here about octoprint-upgrade-to-py3 HOT 14 CLOSED

WARNING: You are using pip version 21.1.2; however, version 21.1.3 is available.
You should consider upgrading via the '/home/pi/OctoPrint/venv/bin/python -m pip install --upgrade pip' command.

This is a warning directly from pip, not the script, I have no control over this.

Required dependency requests is missing... No plugins can be installed

This means the python3-requests package is not installed on your system - it has nothing to do with the pip warning above. It is generally available in most OS installs, and it is needed to download the plugin repository list to find all the install locations as they are not on PyPi, and have to be installed using a URL instead. I haven't had an issue with people not having this package before, but there is error handling (as you found) to help try and explain what happened. I should probably make the warning show at the beginning of the script as well, so you know before you perform the upgrade.

I will test and release an update in the next few days that helps with some of these issues, now that we have dug into the causes. It's very difficult to work for everyone, so outside of OctoPi installs this is not well tested.

What happens if you run the command python -m virtualenv --python=/usr/bin/python3 /home/pi/OctoPrint/venv_test?

from octoprint-upgrade-to-py3.

(Side note) I am aware, that that command above is not very OS-agnostic, so if that doesn't work, try this one:

python3 -m venv /home/pi/OctoPrint/venv_test

python3 -m venv /home/pi/OctoPrint/venv_test

Thanks for the reply!
The new venv is created without problems.

from octoprint-upgrade-to-py3.

When the script fails it renames the current venv to venv.bak if this is useful for you, but the new one is not created.

from octoprint-upgrade-to-py3.

Which command have you used to create that? I see you quoted the reply with the alternative one, just wanted to confirm that the first one failed - if the second works, I think it makes more sense to make the script use that one instead.

I use the second.
Never tried the first.

Please try the first, and report back whatever error you find, as I said if that doesn't work, try this one

Please try the first, and report back whatever error you find, as I said if that doesn't work, try this one

The result:

/usr/local/bin/python3.9: No module named virtualenv

Then I install virtualenv for Python v3.9.5:

pip3 install virtualenv

And when I try to create again venv:

FileNotFoundError: [Errno 2] No such file or directory: '/usr/bin/python3'
The right path here is: /usr/local/bin/python3.9

from octoprint-upgrade-to-py3.

By modifying your script with the working command for the creation of the venv then the result is this:

There is something misconfigured in my file system?
I don't understand why if in this way it installs Octoprint correctly then it doesn't install the plugins, maybe because once installed it doesn't find the updated version of pip before installing the plugins?

from octoprint-upgrade-to-py3.

This is the content of the wrong venv after go back:

Thanks for the explanation!
"pip3 install requests" and now everything works!

I'm trying on Orange Pi (Ubuntu 16.04.7 LTS and OctoPrint 1.7.2) to upgrade to python ver. 3 with python 2.7. When executing upgrade.py I get error: E: Command line option --allow-releaseinfo-change is not understood in combination with the other options
