For everybody who has an issue with the text: your-dns-needs-immediate-attention
for example:

ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
Errno::ECONNREFUSED: Connection refused - connect(2) for "" port 443 (

This is problably because the .dev and .local are now valid top level extensions.

i had to solve this, add “search home.local” to “/etc/resolv.conf”
(actually added this to “/etc/resolvconf/resolv.conf.d/head”)
