What's preventing CU18 from installing ?
Решение
Ok I found this article
It says my CU update fails because of Default Log path does not exist anymore
Default Log path can be checked by one of below ways:
- Execute T-SQL
exec [master].sys.xp_regread
@rootkey='HKEY_LOCAL_MACHINE',
@key='SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL14.MSSQLSERVER\MSSQLServer\',
@value_name = 'DefaultLog'
- SSMS -> Right Click Server -> Properties -> Database Settings -> Database Default Locations
- Regedit ->
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL14.MSSQLSERVER\MSSQLServer\DefaultLog
Updated Default Log path to point to existing location, and CU18 update installed fine without any errors
