Package: network-manager
Version: 1.27.90-3
Severity: normal
After upgrading to 1.27.91-1, I've found that connecting to my VPN causes
my existing "nameserver" option to disappear from /etc/resolv.conf.
Before connecting:
----
# Generated by NetworkManager
nameserver 192.168.1.1
----
After connecting (actual search domains obfuscated):
----
# Generated by NetworkManager
search foo bar baz
----
I've downgraded back to version 1.27.90-3 which restores the desired behavior
of retaining the existing nameserver setting:
----
# Generated by NetworkManager
search foo bar baz
nameserver 192.168.1.1
----
Note that I have the VPN's "DNS / Automatic" toggle disabled.
