[Koha] Error when tryin to log in to the Staff Interface

Hi, My name is Tomasz and I am new to Koha community. I have run into a problem when installing Koha for the first time. I have failed on step when after initial setup, web installer and on-boarding tool I tried to log in to the Staff Interface. This is the error I get: Software error: DBIx::Class::Storage::DBI::_dbh_execute(): Table 'koha_rasuwacommunity.library_groups' doesn't exist at /usr/share/koha/lib/Koha/Objects.pm line 129 I did koha-upgrade-schema, koha-rebuild-zebra, but nothing worked. I am using Ubuntu19.10, stable latest Koha and mysql 8.0.18. Can you please help? Thank you in advance. Happy Christmas all!!! -- Sent from: http://koha.1045719.n5.nabble.com/Koha-general-f3047918.html
