Dear Professionals,

I am new to koha. I was using koha17.05 on ubuntu mysql version 5.5.14.
When I tried to update koha from 17.05 to 19.05, I got the following error
message. I have updated  koha-upgrade-schema library also. But same error
is appearing on the opac.
Software error:

DBIx::Class::Storage::DBI::_dbh_execute(): Table
'koha_library.library_groups' doesn't exist at
/usr/share/koha/lib/Koha/Objects.pm line 130

For help, please send mail to the webmaster ([no address given]), giving
this error message and the time and date of the error.
 I am in need of your help. I really appreciate your reply.
Thanks,
Ashok
