[Samba] Upgrade from 4.6.7 to 4.17.4 fails with database problem (Failure during re-pack, so transaction must be aborted)

[Ricardo Esteves]

Hi,

Thank you for help, probably updating using another host and use join, 
or demoting one of my DCs (i have 2, DC1, and DC2) upgrade and then join 
the demoted one, and then do the same for the other is the best way.

But actually last night i was able to do the inplace upgrade 
successfully , basically the problem was on DC1 (probably had some bad 
old entries on the db), what i did was transfer all the fsmo roles to 
DC2, demote DC1, and then i did the inplace upgrade of DC2 and went ok. 
Now i need to upgrade and join DC1 back.

Btw, in order to avoid the issue you mentioned (I would never recommend 
upgrading a self compiled version of Samba in this way. There have been 
instances of files being removed from the version of Samba that you are 
upgrading to, that still exist on disk) what i usually do is remove
/usr/local/samba/bin|sbin|share|lib|lib64|libexec
i leave only  /usr/local/samba/etc|private|var
and then i do the ./configure / make / make install

Best regards.
