Installation fails/times out with: "FAILED: add-apt-repository -y ppa:duplicity-team/duplicity-release-git"

[gittbuh]

Hi there,

I am trying to install MIAB in a VPS (KVM) 1GB memory, 10GB disk, Ubuntu 22.04 following the setup guide. The script appears to run ok and just after I have selected my hostname, the installation hangs/times out with a "FAILED: add-apt-repository -y ppa:duplicity-team/duplicity-release-git" message over and over. The full error details pasted below:

FAILED: add-apt-repository -y ppa:duplicity-team/duplicity-release-git

Any ideas? Thanks in advance.

I googled the thing and found the solution here: https://discourse.mailinabox.email/t/unable-to-install-fails-solved/9879/25

Install bind before miab and edit /etc/bind/named.conf.options, change "dnssec-validation auto" to "dnssec-validation yes"

Thanks a lot to the person who posted this, I would have never figured this out.

No idea why this is happening to some of us though. It should probably be mentioned in the installation guide if it isn't already.

Another possible issue people may run into is if they run for example an ec2 instance with a private ipv6 I founf I need to at least temporarily disable ipv6 while I do the update as it tried to translate the repository via ipv6 instead of ipv4 but only throws the error listed.
To temporarily disable ipv6:
sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.lo.disable_ipv6=1
then run the install, with the above 3 lines ipv6 will be reenabled on reboot.
