@Dhanus3133 thanks for the PR! I'll give it a round of testing first thing tomorrow.

@Dhanus3133 thanks for the PR! I'll give it a round of testing first thing tomorrow.

Thanks! However, I’m running into an issue with the custom user stage for package installation. You can check the logs here.

Error: pi-gen build failed with exit code 100
mkfs.fat: Warning: lowercase labels might not work properly on some systems

When I skip the custom stage, the CI build from my fork runs successfully, as build images in this release. I also tried reaching out to you via Discord.

[Dhanus3133]

@billz resolved the issue. It should now be good for testing. You can use the build image from the fork.

[billz]

@Dhanus3133 I'll give each image a thorough test. thanks!

Testing the 64-bit image. A couple of observations:

1. The optional flags are set to '0' (--openvpn 0 --restapi 0 --adblock 0 --wireguard 0 --tcp-bbr 0). Per the issue, these values should be '1'.
2. The dhcpcd package isn't present in the final image, which is required to assign IP addresses to clients. This isn't necessarily a fault of the action, but possbily related to ubuntu-latest used by pi-gen and the OS detection done by the installer.

The first point should be easily fixed. Will need to give the latter a closer look. Otherwise looking good.

Interestingly, the build-raspap-image (64-bit, arm64) log indicates that the package is installed:

RaspAP Install: Installing required packages
  php8.2-cgi will be installed from the main deb sources list
  dhcpcd5, iw and rsync will be installed from the main deb sources list

Also noticed that routing and IP masquerading fails in the build:

Checking iptables rules
/usr/bin/grep: /etc/iptables/rules.v4: No such file or directory
Adding rule: -t nat -A POSTROUTING -j MASQUERADE
iptables: Failed to initialize nft: Protocol not supported
[ error ]  Unable to execute iptables 
/usr/bin/grep: /etc/iptables/rules.v4: No such file or directory
Adding rule: -t nat -A POSTROUTING -s 192.168.50.0/24 ! -d 192.168.50.0/24 -j MASQUERADE
iptables: Failed to initialize nft: Protocol not supported
[ error ]  Unable to execute iptables 
Persisting IP tables rules
iptables-save/1.8.9 (nf_tables) Failed to initialize nft: Protocol not supported
[ error ]  Unable to execute iptables-save

I haven't looked more closely to determine the cause. Hopefully these are minor fixes that can be resolved.

1. The optional flags are set to '0' (--openvpn 0 --restapi 0 --adblock 0 --wireguard 0 --tcp-bbr 0). Per the issue, these values should be '1'.

Regarding this, I believe enabling OpenVPN may be causing a DNS issue in the export-image stage, specifically during the package installation for the user rename step (linked here for reference: https://github.com/RPi-Distro/pi-gen/blob/master/export-image/01-user-rename/00-packages). This error seems related to network configuration changes when OpenVPN is enabled, as described in this related comment. Do you know if there’s a workaround to bypass this DNS issue?

Thanks, this didn't work out, but there was a simple way to fix it.

All the required packages are installed, but since the actual error is hidden, I'm not sure how to solve this issue. Let me know what do you think about this.

You can find the latest build images for all the enabled flags here.

PS: Can you please verify if that installed properly, cause I noticed the new build images are much more smaller than the previous builds.

[billz]

Pulling the latest 64-bit image now.

@billz Can you test this release build for the commit 38ce0ec? You can find the release here: test release. It should work, but please note that this build was created through a custom fork of my pi-gen repository. You can check the changes here on the arm64 branch: pi-gen/arm64.

I believe these changes are required to ensure the builds succeed without any issues related to networking.

If you think this is a viable solution, we can consider forking pi-gen into the RaspAP org, make the necessary changes, and use that fork repository within the pi-gen-action.

Let me know your thoughts!
