Thanks for this hint!

After all we found out the database dump I was provided with was corrupt
or unusual in at least two ways: 1) it didn't contain the final line
"Dump completed" and so really was incomplete, but 2) it did include
lines like the following (and the corresponding SQL commands) that are
usually not included in the database dump:
-- Constraints der exportierten Tabellen
-- Constraints der Tabelle `accountlines`
-- Constraints der Tabelle `account_credit_types_branches`
etc. etc.
Provided with an incorrupt dump I was able to load it into the MariaDB
server and the update from Koha 19.11 to 24.05 worked like a charm. No
errors at all.
Best wishes and many thanks for your help: Michael

1. On an different host with Koha 23.11 I loaded the database which
then showed the following error:
ERROR 1452 (23000) at line 8292833: Cannot add or update a child row:
a foreign key constraint fails (`koha_test`.`#sql-alter-368-2a`,
CONSTRAINT `borrower_message_transport_preferences_ibfk_1` FOREIGN KEY
(`borrower_message_preference_id`) REFERENCES
`borrower_message_preferences` (`borrower_)
2. I didn't care for it and then tried to update the database. This
time the update process went far far further but it still aborted here:
Upgrade to 23.06.00.013 [17:56:51]: Bug 28966 - Holds queue view too
slow to load for large numbers of holds
ERROR - {UNKNOWN}: DBI Exception: DBD::mysql::db do failed: Can't DROP
CONSTRAINT `tmp_holdsqueue_ibfk_1`; check that it exists at
/usr/share/koha/lib/C4/Installer.pm line 741
This seems to be a different problem and I'm hoping the solution could
lead to the road of success... Do you happen to know how to solve this?
3. Furthermore I saw the database dump file I received for the update
ends like this:
--
-- Constraints der Tabelle `virtualshelves`
--
ALTER TABLE `virtualshelves`
ADD CONSTRAINT `virtualshelves_ibfk_1` FOREIGN KEY (`owner`)
REFERENCES `borrowers` (`borrowernumber`) ON DELETE SET NULL ON UPDATE
SET NULL;
COMMIT;
/*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */;
/*!40101 SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS */;
/*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION */;
while the database dump files I usually create myself do not contain
constraints at all and end like this:
-- Dump completed on 2024-07-10 6:25:22
Does this make sense to you?
Best wishes: Michael
