Unable to Perform Custom Tweaks Within Lite Image

[Arszilla]

I am attempting to install some custom packages and tweaks for my custom Raspberry Pi OS for my Raspberry Pi Zero and Raspberry Pi 4, while generating a lite image, as I do not need a DE etc. The images are customized using a config like the one below:

IMG_NAME="raspbian"
DEPLOY_COMPRESSION="xz"
TARGET_HOSTNAME="raspbian-pi4"
KEYBOARD_KEYMAP="us"
KEYBOARD_LAYOUT="English (US)"
TIMEZONE_DEFAULT="Europe/Tallinn"
FIRST_USER_NAME="arszilla"
DISABLE_FIRST_BOOT_USER_RENAME=1
ENABLE_SSH=1
PUBKEY_SSH_FIRST_USER="ssh-ed25519 REDACTED"
FIRST_USER_PASS="REDACTED"

Inside of stage2, I have a folder named 04-custom-tweaks. The layout of thestage2` is as follows:

$ tree -a

├── EXPORT_IMAGE
├── EXPORT_NOOBS
└── prerun.sh

As seen above, 04-custom-tweaks contains packages and 01-run.sh, similar to how the other folders are structured. The custom packages I am installing are as follows:

curl
docker.io
git
htop
locate
neofetch
tmux
wget
xdg-user-dirs
zsh

Since I am installing docker.io and zsh, I am attempting to add my FIRST_USER_NAME to the docker group, and install oh-my-zsh to both FIRST_USER_NAME and root, with the following 01-run.sh script:

#!/bin/bash -e

on_chroot << EOF
# If the docker group exists, add the FIRST_USER_NAME to it
if getent group docker >/dev/null; then
    usermod -aG docker ${FIRST_USER_NAME}
fi

# Replace the default shell for all users to zsh
chsh -s /usr/bin/zsh ${FIRST_USER_NAME}
chsh -s /usr/bin/zsh root

# Install oh-my-zsh 
sudo -u ${FIRST_USER_NAME} sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)" "" --unattended
sudo -u ${FIRST_USER_NAME} git clone https://github.com/zsh-users/zsh-autosuggestions /home/${FIRST_USER_NAME}/.oh-my-zsh/plugins/zsh-autosuggestions
sudo -u ${FIRST_USER_NAME} git clone https://github.com/zsh-users/zsh-completions /home/${FIRST_USER_NAME}/.oh-my-zsh/plugins/zsh-completions
sudo -u ${FIRST_USER_NAME} wget -O /home/${FIRST_USER_NAME}/.zshrc https://gitlab.com/Arszilla/dotfiles/-/raw/main/etc/skel/.zshrc

# Install oh-my-zsh for root
sudo -u root sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)" "" --unattended
sudo -u root git clone https://github.com/zsh-users/zsh-autosuggestions /root/.oh-my-zsh/plugins/zsh-autosuggestions
sudo -u root git clone https://github.com/zsh-users/zsh-completions /root/.oh-my-zsh/plugins/zsh-completions
sudo -u root wget -O /root/.zshrc https://gitlab.com/Arszilla/dotfiles/-/raw/main/etc/skel/.zshrc
EOF

I can't seem to install oh-my-zsh for both my user and root, as I am getting the following error:

Can I request your assistance on how can I fix this so I can have my images built the way I need them?

Thanks!

I think the issue is your use of $(...). Escape it so that it's \$(...).

[Arszilla]

That should not be the issue, as seen in stage1/01-sys-tweaks/00-run.sh.

Additionally, I am using { }, not ( ).

[XECDesign]

Take an extra moment to think about this.

[Arszilla]

Correct me if I am wrong, but in your statement above, you've said:

I think the issue is your use of $(...). Escape it so that it's \$(...).

This statement means that my usage of $(...) (which doesn't exist in my script, as I used ${...}) is the cause, and I should use \ to escape it, which is inapplicable.

I did try using:

• ${FIRST_USER_NAME}
• "${FIRST_USER_NAME}"
• \${FIRST_USER_NAME}

All failed with the same error:

[XECDesign]

You have round brackets here: $(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)

[Arszilla]

I am utterly stupid for not realizing the curl command. I sincerely apologize if I came off rude as I totally missed that line. I was too focused on ${FIRST_USER_NAME} for some reason, thinking the issue was there.

Thanks for the pair of eyes @XECDesign, and apologies once again.

[XECDesign]

No, no problem at all. Hope it all works now.
