We are on the way to migrate all our Plone Sites to a new Linux Server.
After having rsynced to Zope Instances to the new server we tried to start them with
./bin/plonectl start
Then we get the message:
Traceback (most recent call last):
File "./bin/plonectl", line 10, in
import plone.recipe.unifiedinstaller.ctl

import zc.recipe.egg
ImportError: No module named recipe.egg
When we try a buildout, it does work with this message:
Traceback (most recent call last):
File "./bin/buildout", line 6, in
from zc.buildout.buildout import main

When we make new PLONE Installation on the new server, it works fine, so the basic requirements should be there. (?)
The old Linux Version was Debian 8.11, the new one is Debian 10
But in meantime we have another Problem:
After copying more PLONE Instances from the old to the new server (and replacing the python binary) those Instances that have PLONE 5 bring the error listed below when starting ./bin/plonectl fg, while the PLONE 4 instances work fine.
Error messages:
"2021-07-07 18:26:22 ERROR Application Could not import Products.ATContentTypes"
... Traceback ...
"ImportError: /home/users/mlpd/Plone5_newlinux/buildout-cache/eggs/lxml-3.5.0-py2.7-linux-x86_64.egg/lxml/etree.so: undefined symbol: PyFPE_jbuf"
How can I make reinstalling local lxml ?
Buildout did not help.
lxml is globally installed in /usr/lib/python2.7/dist-packages.
I hhave no experience with virtual_env
