Re: [Unity-idm-discuss] Recommended server resources

[D B. <ba...@aw...>]

Hi!

thanks! I've now picked 4 GB RAM, 2 cores and 40 GB of disk space on a
CentOS 8 instance with
java-11-openjdk-headless-11.0.5.10-2.el8_1.x86_64.
But installing the rpm throws an error:

dnf install unity-idm-3.2.0-1.noarch.rpm
Last metadata expiration check: 0:33:00 ago on Wed 26 Feb 2020 13:52:54 UTC.
Error:
 Problem: conflicting requests
  - nothing provides osgi(org.glassfish.hk2.hk2) needed by
unity-idm-3.2.0-1.noarch
(try to add '--skip-broken' to skip uninstallable packages or '--nobest'
to use not only best candidate packages)

But the manual promises me that I need nothing but java11! ;-)

Cheers,
D
