v6 - Ubuntu 18.04.2 - dnsmasq

[efga]

I installed v6 on a fresh Ubuntu 18.04.2 minimal by doing the following:

Code Select Expand

apt get update
wget http://www.sailpbx.com/sail/sail-6.0/debs/noarch/sail_6.0.1-44+ubuntu18_all.deb
wget http://www.sailpbx.com/sail/sail-6.0/debs/amd64/sailhpe_6.0.0-2_amd64.deb
wget http://www.sailpbx.com/sail/sail-6.0/debs/repo/pool/main/a/ast-en-gb-gpl-gsm-sounds/ast-en-gb-gpl-gsm-sounds_4.0.0-5_all.deb
sudo apt install ssmtp
sudo apt install ntp
sudo apt install asterisk
sudo apt install ./sailhpe_6.0.0-2_amd64.deb
sudo apt install ./sail_6.0.1-44+ubuntu18_all.deb
sudo apt install ./ast-en-gb-gpl-gsm-sounds_4.0.0-5_all.deb

But whenever sail is installed DNS resolution fails after the system is restarted; error given during the installation:

To address this I have done the following:

Code Select Expand

sudo mkdir /run/systemd/resolve/
sudo nano /run/systemd/resolve/stub-resolv.conf

Finally, I added the following to the stub-resolv.conf

search example.local
nameserver 192.168.0.1

Are you able to ensure that the installer doesn't cause this issue going forward on Ubuntu 18.04.2?

Hi

Ubuntu18 is still very much an alpha install and it has not had major testing yet.  That's not an excuse it's just the way we have to allocate our scarce resources.   Most go into Debian and in particular Debian 9.   I have logged your issue and we will look at it as soon as we can.

Thank you for your input it is very valuable.   Please continue to give us input on Ubuntu18 if you are able.

Kind Regards
