Dear all, now I am promoted from a plain KOHA user to the system administrator of the computer hosting a KOHA installation of a railway museum in Germany. My first task was to upgrade the system from Ubuntu 16.04 to 20.04 and upgrading the KOHA system. I have tried this first twice on some local copies. In the test runs the database upgrade works fine. In the update run of the production system it stops at this point: Upgrade to 20.12.00.049 [19:01:13]: Bug 28108 - Move action logs 'SERIAL CLAIM' and 'ACQUISITION CLAIM' to a new 'CLAIMS' module Upgrade to 20.12.00.050 [19:01:13]: Bug 28108 - Add new systempreference OpacHiddenItemsHidesRecord Upgrade to 21.05.00.000 [19:01:13]: Koha 21.05.00 release Log started: 2022-03-29 19:04:34 # some other program In thetest runs it continues Upgrade to 21.05.00.000 [17:49:33]: Koha 21.05.00 release Upgrade to 21.06.00.000 [17:49:33]: Increase DBRev for 21.06 Run, rabbit run. Dig that hole, forget the sun, And when at last the work is done Don't sit down it's time to dig another one. The rabbitmq log show these entries for the time 2022-03-29 19:00:36.018 [info] <0.595.0> started TCP listener on [::]:5672 2022-03-29 19:00:36.018 [info] <0.266.0> Running boot step cluster_name defined by app rabbit 2022-03-29 19:00:36.018 [info] <0.266.0> Running boot step direct_client defined by app rabbit 2022-03-29 19:00:36.158 [notice] <0.103.0> Changed loghwm of /var/log/rabbitmq/rabbit@tools.log to 50 2022-03-29 19:00:36.496 [info] <0.8.0> Server startup complete; 0 plugins started. 2022-03-29 19:03:25.195 [info] <0.777.0> rabbit_stomp: default user 'guest' enabled 2022-03-29 19:03:25.281 [info] <0.793.0> started STOMP TCP listener on [::]:61613 2022-03-29 19:03:25.329 [info] <0.765.0> Plugins changed; enabled [amqp_client,rabbitmq_stomp] 2022-03-29 19:03:27.678 [info] <0.800.0> RabbitMQ is asked to stop... Is there any way to continue the database upgrade? I have other applications running on the system and I do not want to start the complete upgrade process again. It seems that the not executed scripts are in /usr/share/koha/intranet/cgi-bin/installer/data/mysql/db_revs Basically the upgraded KOHA is running. Best regards Harald
