[Bug] python3 segfaults after upgrade
DemoFreak opened this issue · 3 comments
Describe the bug
After successfully running the upgrade script python3 segfaults.
Even running it as another user (root) segfaults, so I guess it has nothing to do with the environment.
Script output
pi@octopi:~ $ python3 upgrade.py
OctoPrint Upgrade to Py 3 (v2.1.7)
Hello!
This script will move your existing OctoPrint configuration from Python 2 to Python 3
This script requires an internet connection and it will disrupt any ongoing print jobs.
It will install the latest version of OctoPrint (1.4.2) and all plugins.
No configuration or other files will be overwritten

Something very broken with your underlying system I think. It barely touches the system wide python install, with just one exception, everything else is installed into a new virtual environment, created from using Python 3 instead of 2.
The only thing that touches system wide installation is installing python3-dev, using apt - and it appears that ran through successfully, from your paste above. That's the only thing that could potentially cause this, if you have a slightly corrupted Python 3 install, or All I can recommend is there must be some apt commands to repair broken packages, but I don't know them.
There's not a lot else I can suggest apart from that, if you have any thoughts let me know.
The underlying system is a clean octopi 0.17 installed from image file.
The only thing I changed is adding the pi user to the sudoers.
Something happened whilst the upgrade, as the upgrade script was running fine (so python3 was working then), and immediately afterwards python3 segfaults.
I have no idea but reinstalling the system from scratch, as apt seems to depend on python3, so reinstalling python3 via apt fails too.
Seems to be a SD card issue.
Reinstalled the system from scratch now and tried the upgrade several times, each attempt failed for some other reason.
Sorry for disturbance.
