[Koha] Initial difficulties installing Koha via packages per wiki instructions

[C.S. Hayward]

I have tried to install Koha from the command line on a Jessie VPS, and have run into errors relating to certificates.

I would appreciate any help; a copy-paste of my first attempt is as follows:

Linux technoluddites.org 4.19.0-9-amd64 #1 SMP Debian 4.19.118-2+deb10u1 (2020-06-07) x86_64
