I've successfully upgraded koha from version 3.22.21 to version 19.05.17 (in ubuntu 18.04 server) using only the tarball file because v3.22.21 was also installed from the tarball. I didn't use any koha repository during its installation/upgrade and therefore I don't have any "koha-common" service/package!. The problem is in zebra, zebra indexer doesn't work in the crontab, although cron works without any problem. I've koha-zebra-daemon service (link to the "/usr/share/koha/bin/koha-zebra-ctl.sh" script), which also works (as I think) because, when I run the command: # service koha-zebra-daemon status output is following: ------------------------------------------------------------------------------------------------------- ● koha-zebra-daemon.service - LSB: Zebra server daemon for Koha indexing Loaded: loaded (/etc/init.d/koha-zebra-daemon; generated) Active: active (running) since Thu 2021-10-28 13:51:55 +04; 2h 26min ago Docs: man:systemd-sysv-generator(8) Process: 541 ExecStart=/etc/init.d/koha-zebra-daemon start (code=exited, status=0/SUCCESS) Tasks: 2 (limit: 9488) CGroup: /system.slice/koha-zebra-daemon.service ├─584 daemon --name=koha-zebra-ctl.koha --errlog=/var/log/koha/koha-zebradaemon.err --stdout=/var/log/koha/koha-zebradaemon.log └─637 /usr/bin/zebrasrv -v none,fatal,warn -f /etc/koha/koha-conf.xml Oct 28 13:51:55 ubuntu systemd[1]: Starting LSB: Zebra server daemon for Koha indexing...

On the other hand, if I run the command(which is in the cron) in the shell: $ KOHA_CONF=/etc/koha/koha-conf.xml /usr/share/koha/bin/migration_tools/ rebuild_zebra.pl -b -a -z the new biblioitems are appearing in the search results. I have no ideas how to solve the problem. Can anybody help me?
