What is the problem?

I updated Octoprint to version 1.7.3, then I updated my raspberry pi. Now Octoprint is not starting anymore.

What did you already try to solve it?

Connected to the Raspberry via ssh, then:
sudo service octoprint stop
source ~/oprint/bin/activate
octoprint serve --debug --host 127.0.0.1

Traceback (most recent call last):
  File "/home/pi/oprint/bin/octoprint", line 6, in <module>
    from pkg_resources import load_entry_point

    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'urllib3>=1.25.7; python_version <= "3.4"' distribution was not found and is required by sentry-sdk

Then I tried to update my sentry-sdk via pip install --upgrade sentry-sdk

Then I checked my Python version:

pi@octopi:~ $ python3 --version
Python 3.5.3

Then I removed Python 3.5 from the system by sudo apt-get remove python3.5, then sudo apt-get purge python3.5 and then sudo apt remove python3.5-minimal

Now I get:

pi@octopi:~ $ python3 --version
-bash: /usr/bin/python3: No such file or directory

and

pi@octopi:~ $ python --version
Python 2.7.13

Result is still the same. No change on the output of octoprint serve --debug --host 127.0.0.1

Have you tried running in safe mode?

Yes, no change. Same error message

Systeminfo Bundle

Cannot get Systeminfo because:

(oprint) pi@octopi:~ $ octoprint systeminfo .

Additional information about your setup

``` Linux octopi 4.19.66-v7+ #1253 SMP Thu Aug 15 11:49:46 BST 2019 armv7l ------------------------------------------------------------------------------ OctoPrint version : 1.7.3 OctoPi version : 0.16.0 ------------------------------------------------------------------------------

OctoPrint 1.7.3 is an old version, and Python 2 is no longer supported on newer (1.8.x+) installs. I would recommend that you upgrade the OS on your Pi (OctoPi 0.16 is too old to install Python 3.7+, only 0.17 & newer can do that), so that you can try and install the latest version of OctoPrint instead of the older 1.7.x.
