Updated Octoprint today, and now it won't start

What is the problem?

I ran the updates from the gui today, and after it rebooted, Octoprint won't start

What did you already try to solve it?

Manually starting the service, it won't start, gives error:
ImportError: /lib/arm-linux-gnueabihf/libc.so.6: version `GLIBC_2.34' not found

ran apt update & apt upgrade. rebooted. no change.
ran apt install libc6, already latest version.

Have you tried running in safe mode?

Yes

Did running in safe mode solve the problem?

No

Systeminfo Bundle

You can download this in OctoPrint's System Information dialog ... no bundle, no support!)

Unlike the other issue you are running the latest python 3.9 version in bullseye. What do you get if you run the following command?

source ~/oprint/bin/activate
pip install --force-reinstall --no-cache-dir octoprint
deactivate

Still erring on GLIBC_2.34 not found.

have you tried updating the system files?

sudo apt update
sudo apt upgrade -y
7

Yes, I did.

8

For me this did the trick:

source ~/oprint/bin/activate   # activate OctoPrint venv
pip uninstall -y psutil
pip install --no-binary=:all: "psutil>=6.1.1,<7"

I have the exact same issue. Updated for the first time in 2 years and octoprint was not working. I checked the logs and had the same issue

10

Probably the Raspbian version is too old and that Python package was compiled using a newer version of glibc. Unfortunately there’s not really a good way to upgrade. Running the normal full-upgrade command will not update to a new major version of Raspbian/Raspberry Pi OS.

I had the same issue and resolved it by reflashing the latest version onto a new SD card.

11

That fixed it, thanks!

I'd post this in the other post with the same error, but I don't want to get yelled at by @Ewald_Ikemann.

I just had to reflash my pi, and then update Octoprint. Got the same error as the OP, but this solution unblocked me. Thanks!

I just created an account to say thank you!! You saved me hours of Googling.

Same issue, but this worked for me. Thanx!
