[SOLVED] Installing PMG on Lightsail

[zolthar]

I would love to create a backup PMG instance on a cloud hosted VM - has anyone tried installing PMG on a Lightsail instance?

lets assume:
Intance: Debian 10.5 Lightsail AP Region
Public IP = 1.2.3.4
Local IP = 172.26.7.x
fqdn = splaam.domain.com
dns points correctly when ping fqdn

I am trying, however getting the following error and I am not sure of what next:

hostname lookup 'splaam' failed - failed to get address info for: splaam: Name or service not known
dpkg: error processing package pmg-api (--configure):
installed pmg-api package post-installation script subprocess returned error exit status 22
dpkg: dependency problems prevent configuration of proxmox-mailgateway-container:
proxmox-mailgateway-container depends on pmg-api; however:
  Package pmg-api is not configured yet.

dpkg: error processing package proxmox-mailgateway-container (--configure):
dependency problems - leaving unconfigured
Processing triggers for libc-bin (2.28-10) ...
Processing triggers for systemd (241-7~deb10u5) ...
Errors were encountered while processing:
pmg-api
proxmox-mailgateway-container

NOTE: I have changed the following hosts file to reflect the change Stoike had advised below.
/etc/cloud/templates/hosts.debian.tmpl

#{# The value '{{hostname}}' will be replaced with the local-hostname -#}
#127.0.1.1 {{fqdn}} {{hostname}}
#127.0.0.1 localhost
1.2.3.4 splaam.domain.com splaam

/etc/hosts

1.2.3.4 splaam.domain.com splaam

/etc/hostname

splaam.domain.com

/etc/mailname

splaam.domain.com

/etc/postfix/main.cf

myhostname = splaam.domain.com
mydestination = $myhostname, splaam.domain.com, localhost.domain.com, , localhost
relayhost =
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128

/etc/apt/sources.list

# PMG Repository

What have I not defined?

Any help is much appreciated.

1.2.3.4 splaam.domain.com

try adding the short nodename ('splaam') to that line as well:

1.2.3.4 splaam.domain.com splaam

(without testing on a hunch)

I hope this helps!

Thanks Stoiko, I am not sure if yours added, however it passed that error and thrown the following now:

E: Sub-process /usr/bin/dpkg returned an error code (1)

To get to the above, I had changed the following:

/etc/cloud/templates/hosts.debian.tmpl

1.2.3.4 splaam.domain.com splaam

/etc/dhcp/dhclient.conf

supersede domain-name "splaam.domain.com";
prepend domain-name-servers 1.1.1.1, 9.9.9.9;

cat /etc/resolv.conf

domain splaam.domain.com
search splaam.domain.com
nameserver 1.1.1.1
nameserver 9.9.9.9

Firewall
I had also opened ALL PORTS/Protocols for this test purpose.

psql: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

is postgresql installed and running? ...

 

[zolthar]

it occured during the installation process during this command:

sudo apt install proxmox-mailgateway-container

So I am not certain whether it would have been installed or not and if its during the install process, I am assuming it should have been installed and started.

Still learning on the CLI, and after every failed install, I am deleting the instance and restarting as the install does not seem to continue - probably I am not aware of the correct command to continue installation.

 

[zolthar]

I just did a re-install and added only your suggestion for the /etc/cloud/templates/hosts.debian.tmpl and it has completed the installation.

I opened port 8006 and it is now responding - so will do some config and testing.

Thanks heaps Stoiko.

Glad that worked - please mark the thread as 'SOLVED' - this helps others who also want to run PMG on Lightsail
