Sorry, the screenshot has been forgotten!

I don't want to hijack this thread, but I downloaded the installer above yesterday and while the SOGo option is there, the install fails to load SOGo with a pgp key error.

Today I tried to install this, but SOGo fails the install. When I try to install it with Roundcube only - it installs perfectly.

OS is a fresh Ubuntu 20.04 LTS last updated 10/1/22 if that is relevant.

Here is the relevant response following execution of: apt update && apt upgrade

W: GPG error: https://packages.inverse.ca/SOGo/nightly/5/ubuntu focal InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 19CDA6A9810273C4
E: The repository 'https://packages.inverse.ca/SOGo/nightly/5/ubuntu focal InRelease' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.

This is from 1050 on 12/01/21022 GMT.

Latest update ...
Please ignore what follows below - I found the error - firewall restriction.

Thank you

Nope, here is what I got ...

Ran apt update && apt upgrade which finished with ...

W: GPG error: https://packages.inverse.ca/SOGo/nightly/5/ubuntu focal InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 19CDA6A9810273C4

Then ran your code as below getting ..

Executing: /tmp/apt-key-gpghome.8VySWchIvY/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-key 0x810273C4
gpg: keyserver receive failed: Connection timed out

Any ideas?

An error with apt-key is found more often here in the forum. Mostly it is because apt-key can not reach the key server via port 11371 because a firewall or proxy prevents this.

The solution in this case is very simple and I wonder why this is not changed in the appropriate script, after all, there was the error here nice often and a corresponding solution can be found here in the forum already.

In case of the 1.6.0 installation package the following change must be made in the file 'iRedMail-1.6.0/functions/packages.sh'.

Line 379

Original:

apt-key adv --keyserver keyserver.ubuntu.com --recv-key ${SOGO_PKG_MIRROR_APT_KEY}

Edit:

apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-key ${SOGO_PKG_MIRROR_APT_KEY}

Line 383

Original:

apt-key adv --keyserver pgp.mit.edu --recv-key ${SOGO_PKG_MIRROR_APT_KEY}

Edit:

apt-key adv --keyserver hkp://pgp.mit.edu:80 --recv-key ${SOGO_PKG_MIRROR_APT_KEY}

This will make the script work without problems behind a firewall or proxy.

@ZhangHuangbin it is possible to include this in one of the next versions. The function of the script should not be affected by this and there is one problem less in certain installation scenarios.
