What is the problem?
I get this erro after i manually deleted a old octoprint install ( 1 year old ) and install the latest from git.

Traceback (most recent call last):
File "/usr/local/bin/octoprint", line 5, in
from pkg_resources import load_entry_point

I tried installing 3 times and got the same eroor

Hi @ekaggrat!

You did not tell us about the system you run OctoPrint on: Raspberry Pi, PC?
Was the old one a OctoPi installation? Was is installed to a another OS?

If you have a RasPi with OctoPi on it, it's more easy to reinstall the recent OctoPi and you have all up to date.

It’s a raspberry pi running raspbian . I need to run it along with a regular lcd so I had first installed octoprint after installing raspbian . It was working fine but I didn’t upgrade for over year being lazy . So now it refused to upgrade via the web upgrader . That’s why I deleted the octoprint directory completely and tried to install again though git . But now I get this error

Have you already tried to update/upgrade the Raspian installation before installing the recent OctoPrint?

If it were me, I'd get a new 8GB microSD card and install the new OctoPi image on it per the instructions.

I had this problem and resolved it by manually updating that certifi library:

oprint/bin/pip install certifi -U
