Error migrating from Plone 4.3.15 to Plone 5

amorebietakoUdala · March 13, 2018, 9:18am

Hello,

I'm trying to migrate from plone 4.3.15 to Plone 5.1

I recently migrated successfully from 4.3.1 to 4.3.15. In the way I had to change from LinguaPlone 4.1.3 to plone.app.multilingual 2.0. But I succeded to have a working 4.3.15 site with plone.app.multilingual.

Before this migration, I uninstalled, all not necesary add-ons. Before the migration It has only 6 addons active.

Tipos de contenido Dexterity 2.0.8
Integración de JQuery en Plone 1.7.2
Integración de Herramientas de JQuery en Plone 1.5.5
archetypes.multilingual 2.0
plone.app.collection 1.0.10
plone.app.multilingual 2.0.0

The I tried to migration with the following eggs only:
index = https://pypi.python.org/simple/
extends =
base.cfg

versions.cfg

https://dist.plone.org/release/5-latest/versions.cfg

eggs =
Plone
Pillow

Products.LinguaPlone

plone.app.multilingual[archetypes]

The buildout went ok, I started the client1 with fg no errors there.

But when I when I go to http://server:8080/ in order to run update steps: I get the following:

I´m a newbie, so, maybe I did something wrong, but I'm stuck here, please how do I solve this?

Thanks in advance for your help.

This is the problem.

If you have already migrated from Products.LinguaPlone to plone.app.multilingual then you don't need Products.LinguaPlone in your eggs anymore. I don't think there is a LinguaPlone version that works with Plone 5.

To make the step smaller, I would say:

Go back to Plone 4.3.15.
Deactivate LinguaPlone from the add-ons control panel, if you haven't done so already.
Remove Products.LinguaPlone from the eggs in Plone 4.3.15.
Rerun the 4.3.15 buildout and restart your instance and see if you still have this problem.

Thank you mauritsvanrees.

I went back to the 4.3.15, but if I remove the egg from buildout.cfg, rerun the buildout and restart the site, I get what if think it's the same error in version 4.3.15:

How can I remove those references in other to migrate correctly?

Thank you.

Did you really deactivate LinguaPlone from the add-ons control panel before removing it from the eggs? Properly uninstalling/deactivating LinguaPlone might solve this. That is a guess, but I thought LinguaPlone had reasonable uninstall code.

If that doesn't help, you could also create an issue: https://github.com/plone/Products.LinguaPlone

Otherwise it might help to use https://pypi.python.org/pypi/wildcard.fixpersistentutilities to remove a persistent utility like this. That package works fine if you use it well and know what you are doing but it comes with warnings. Please try it out on a copy first.

Hi maurits,

I deactivated the addon from control panel before removing the egg. That's sure.

I followed this guide to migrate from LinguaPlone to multilingual:

https://github.com/plone/plone.app.multilingual/issues/181

I removed all linguaPlone references with wildcar.fixpersistentutilities, but the problem persisted. The site worked fine with that egg installed but not activated so I decided to go on. Unfortunately, in plone 5 didn't work even deactivated.

So the question is how to remove those SyncedLanguages from version 4.3.15? Anyone solved this?
