Building FullPageOS variant for 64bit

I'm using a Raspberry Pi 5 with 8GB of memory. Everything runs better in 64bit but I noticed FullPageOS is 32-only. How can I build with the 64bit version of Raspian?

On my fork, I'm trying to use a 64-bit GitHub runner with a 64-bit Raspian image URL and I'm getting the following build error:

qemu-arm-static: /usr/bin/bash: Invalid ELF image for this architecture

https://github.com/alectrocute/FullPageOS/actions/runs/14478532329/job/40609993848

It is currently completely impossible to build a new FullpageOS with current Debian/Ubuntu distributions.

Unless the developer changes something in the code, the end is unfortunately in sight for FullpageOS ;-(

@topa-LE

Hey, sorry not to reply sooner. I am pretty busy these days.

Its more than possible to build arm64 builds. I went to length creating CustomPiOS v2 to facilitate that.
See base board section in building:
https://github.com/guysoft/CustomPiOS/wiki/Building#base-board-selection

I am using here both Ubuntu 24.10 and debian bullseye to build. @topa-LE If you have a particular distribution that is causing you issues please provide more details. The docker build method should let you build on any linux machine that can run docker.

If you are using hte docker method, you need to set the base board to raspberrypiarm64

sudo docker exec -it fullpageos-build build -b raspberrypiarm64 -d

I tried to run:

git clone https://github.com/guysoft/FullPageOS.git
cd FullPageOS/src/image
wget -c --trust-server-names 'https://downloads.raspberrypi.org/raspios_lite_arm64_latest'
cd ..
sudo docker run --rm -v `pwd`:/distro --device /dev/loop-control ghcr.io/guysoft/custompios:devel build

but I found a strange error:

+++ detach_all_loopback 2025-10-01-raspios-trixie-arm64-lite.img
+++ image_name=2025-10-01-raspios-trixie-arm64-lite.img

losetup: 2025-10-01-raspios-trixie-arm64-lite.img: failed to set up loop device: No such file or directory
+++ LODEV=
+ exit 1

I checked in my workspace directory and found these:

$ ls -l workspace/
total 4907020
-rw-r--r-- 1 root root 5024776192 Oct 22 21:02 2025-10-01-raspios-trixie-arm64-lite.img

Can anyone help me?

Try running again, its a docker bug.

Also, trixie is not working yet guysoft/CustomPiOS#260

@paspiz85

Try this @paspiz85 :

#!/bin/bash
# Fix Docker loop device exhaustion
# Common issue when building disk images in Docker

echo "Cleaning up loop devices in container..."
docker exec fullpageos-build bash -c "
    # Detach all loop devices
    losetup -D
    
    # Clean up any leftover mounts
    umount -l /distro/workspace/mount/boot/firmware 2>/dev/null
    umount -l /distro/workspace/mount 2>/dev/null
    
    # Remove old image files
    cd /distro/workspace && rm -f *.img
"

echo "Done! Loop devices cleaned up."

@guysoft

I see guysoft/CustomPiOS#259 is closed but also guysoft/CustomPiOS#260 is fixed?

However, I'm retrying building FullPageOS for RaspiOS lite x64 with following commands:

#!/bin/bash
git clone https://github.com/guysoft/FullPageOS.git
cd FullPageOS/src/image
wget -c --trust-server-names 'https://downloads.raspberrypi.org/raspios_lite_arm64_latest'
cd ..
tee docker-compose.yml >/dev/null <<EOF

    volumes:

    devices:

EOF
sudo docker compose up -d
sudo docker exec fullpageos-build bash -c "
    # Detach all loop devices
    losetup -D
    
    # Clean up any leftover mounts
    umount -l /distro/workspace/mount/boot/firmware 2>/dev/null
    umount -l /distro/workspace/mount 2>/dev/null
    
    # Remove old image files
    cd /distro/workspace && rm -f *.img
"
echo "Done! Loop devices cleaned up."
sudo docker exec -it fullpageos-build build
sudo docker compose down

but I haven't workspace directory and my log are:

@guysoft have you any suggestion?

One is closed because it was on a specific topic in trixie, the other is for all the rest.

You can just do the build command with the download option:

sudo docker exec -it fullpageos-build build -d

Also converting this to a discussion. Its not an issue, because its about an issue.
