Correction update with full details (previous comment had formatting loss):

Implemented a root-cause fix for this installer failure and opened PR #2326.

Root cause:

• Guided installer chose /dev/stdin whenever stdin appeared interactive, but some constrained Debian/Proxmox LXC setups deny opening /dev/stdin, causing an early read failure at line 455.

What changed:

• guided_input_stream now probes readability before selecting /dev/stdin.
• Added fallback probing to /proc/self/fd/0 and retained /dev/tty fallback.

Why this resolves it:

• Guided reads no longer hard-fail on unreadable /dev/stdin; installer can continue using a readable interactive stream.

Validation highlights:

• bash -n scripts/bootstrap.sh
• bash -n bootstrap.sh
