Unsure of these troubles. Guacamole app has been successfully uninstalled after 4.4.8 upgrade failed and said that Guacamole is unsupported in 5.0.0.

What should I do now? I will reboot UCS and hope not to see this problem:

The following extensions are incompatible with UCS 5.0:
cn=guacamole,cn=udm_syntax,cn=univention,dc=t24cc,dc=com: [unspecified…unspecified)
cn=guacamole/config,cn=udm_module,cn=univention,dc=t24cc,dc=com: [unspecified…unspecified)

Eventually I will try to remove entries in ActiveDirectory (if any?).

Hello,

I am running on UCS 5.0 now.

Checking python_ucr_template_compatibility ...    FAIL

I have resolved last problem by overwriting Python 2.7 template file from 5.0 release (Python 3):

wget https://raw.githubusercontent.com/univention/univention-corporate-server/5.0-0/base/univention-app-appliance/conffiles/usr/share/univention-web/js/umc/hooks/appliance.json -O /etc/univention/templates/files/usr/share/univention-web/js/umc/hooks/appliance.json

Additionally I faced troubles when server was set to dhcp. It seems that during 4.4.8->5.0.0 upgrade some dhcp packages were causing serious troubles.
I switched server to static IP with

ucr set interfaces/eth0/address=192.168.0.128 interfaces/eth0/broadcast=192.168.255.255 interfaces/eth0/netmask=255.255.0.0 interfaces/eth0/network=192.168.0.0 interfaces/eth0/start=true interfaces/eth0/type=static

and upgrade went smoothly.

I am veryfing now domain joining as “Module: setup_saml_sp” seems to be having problem with fetching configuration. Main Primary DC and Secondary DC are not Univention servers, but MS Windows Server 2019 core instances, so… It is however completely different subject and I am happy I suceeded with upgrade :slight_smile:

Upgrade from 4.4-8 to 5.0-0 fails due to appliance.json
