I've just installed OMV. I'm following the getting started guide. When I try upgrade the popup window shows a bunch of errors like this:
Err:4 http://httpredir.debian.org/debian stretch/main armhf gnupg armhf 2.1.18-8~deb9u4
Could not resolve 'httpredir.debian.org'
Seems a typo somewhere. Is there any way to fix this?
