how, if I can, can I update easily from 17.0?

[cp2004]

As with all OctoPi releases, you have to re-flash your SD card. Easiest way would be to backup your OctoPrint instance and then restore this backup on the new image.

Do you suggest to do the same to upgrade from OctoPi 0.18.0 RC1?

[jneilliii]

yes, that would be the same method.

[Tecnoid69]

yes, that would be the same method.

But with the restore I'll found all the settings? (OctoPrint, OctoScreen...and so on?)

[cp2004]

OctoPrint yes, everything else no.

[MaximilianGaedig]

Will the backup restore plugins, also will the plugins still work? Will python 2 remain? Or will all plugins break bc they still use python 2?

[cp2004]

Backup restores plugins, it reinstalls them to the system. You can check using the plugin Python 3 Compatibility check.

For further questions or support, please use the community forums or discord server, to keep this issue reserved for discussion about the release candidate itself rather than support questions. This is the last one we're answering here. Thanks.

I am testing the OctoPi Release Candidate 0.18.0rc2 version, the printer systematically fails at an irregular interval.

[guysoft]

@Malvu What error is it throwing back?

[jneilliii]

This seems more of an issue with these parameters...

I recommend you read up on this...with possible fixes.

[cp2004]

It's not an OctoPi issue, their post here https://community.octoprint.org/t/critical-resend-ratio/28914/2 - it happened on other versions too.

I had an issue trying to download from the link. I ended up having to download with wget.

Just a heads up. If anyone has any issues, I have uploaded a mirror here
