Can I point you at Louis's repo: https://apt.van-belle.nl/
There you will find packages for the latest Samba versions.

Good, but did you have any problems ?

There are two schools of thought here. You can upgrade your existing
NT4-style domain (yes, the classicupgrade works), but you bring with it
a lot of baggage (very low Unix ID's for one). Starting with a new AD
domain allows to correct all of the old ways of doing things.
If you haven't already donw so, can I suggest you read the Samba wiki:

AD comes with the concept of 'sites', this means that computers at a
specific site will normally only use DC's at that site, the exception
would be if all the DC's at that site went down.
An NT4-style domain relies on SMBv1 and when you upgraded Ubuntu, you
also upgraded Samba to a version that defaults to SMBv2 as a minimum,
this was done by changing the defaults for 'client min protocol' and
'server min protocol' to SMB2_02
You seem to have set 'server max protocol' to 'NT1' , this means that
it is set to less than the 'server min protocol'. This isn't allowed
and will not work, remove the line and set 'client min protocol' and
'server min protocol' to 'NT1'
Any questions, please ask, it is what we are her for.
