If I understand correctly, you are running Koha 20.05 on Ubuntu 20.04. 
As far as I know Koha 20.05 is officially only supported for Ubuntu 18.04:

* Debian 8 (Jessie) with MySQL 5.5 (End of life)
* Debian 9 (Stretch) with MariaDB 10.1
* Debian 10 (Buster) with MariaDB 10.3
* Ubuntu 18.04 (Bionic) with MariaDB 10.1
* Debian 9 (Stretch) with MySQL 8.0 (Experimental MySQL 8.0 support)

See https://koha-community.org/koha-20-05-released/

However, I would do the following:


1. Check if Zebra is really running - otherwise you won't find anything 
in your catalog. The following command

$ ps -ef | grep zebra

should show some processes like the following:

hfs-koha    796      1  0 Apr15 ?        00:00:00 daemon 
--name=hfs-koha-zebra --pidfiles=/var/run/koha/hfs/ 
--errlog=/var/log/koha/hfs/zebra-error.log 
--output=/var/log/koha/hfs/zebra-output.log --verbose=1 --respawn 
--delay=30 --user=hfs-koha.hfs-koha -- /bin/zebrasrv -v none,fatal,warn 
-k 1024 -f /etc/koha/sites/hfs/koha-conf.xml
hfs-koha    797    796  0 Apr15 ?        00:00:00 /bin/zebrasrv -v 
none,fatal,warn -k 1024 -f /etc/koha/sites/hfs/koha-conf.xml
hfs-koha   1068      1  0 Apr15 ?        00:00:00 daemon 
--name=hfs-koha-indexer --errlog=/var/log/koha/hfs/indexer-error.log 
--stdout=/var/log/koha/hfs/indexer.log 
--output=/var/log/koha/hfs/indexer-output.log 
--pidfiles=/var/run/koha/hfs/ --verbose=1 --respawn --delay=30 
--user=hfs-koha.hfs-koha -- 
/usr/share/koha/bin/migration_tools/rebuild_zebra.pl -daemon -sleep 5
hfs-koha   1069   1068  0 Apr15 ?        00:01:47 /usr/bin/perl 
/usr/share/koha/bin/migration_tools/rebuild_zebra.pl -daemon -sleep 5


2. If Zebra is not running, start it using the following command:

$ sudo koha-start-zebra

After you have started Zebra, as above, check if it is really running with

$ ps -ef | grep zebra


3. If you can't start Zebra check your log files:

$ cd /var/log/koha/<instance>
$ more zebra-error.log

There are also other log files in this directory that may give you a hint.


Hope this helps.

Best wishes: Michael
