[Koha] Installation issues

[John Fawcett]

Hi

it's a while since I did an installation, but I did a fresh install of 
21.05 on Ubuntu 21.10 with it-IT language.

I found the following issues.

1. During the install of koha-common I got this message "Failed to 
enable unit: Unit /run/systemd/generator.late/koha-common.service is 
transient or generated."

2. During the install of the it-IT translation I got this message 
despite memcached service is started

Connection to the memcached servers '__MEMCACHED_SERVERS__' failed. Are 
the unix socket permissions set properly? Is the host reachable?
If you ignore this warning, you will face performance issues

3. During the web installer process, marc flavour gives only MARC21 
whereas on the previous install I did I was able to choose UNIMARC.

For 1 and 2 should I open issues on the tracker?

For 3 what needs to be done to get UNIMARC support back into the it-IT 
translation, unless it's been dropped for a reason?

Thanks

John
