Ensure first_time_install.sh runs in non-interactive mode by passing both:
1. The -y command-line flag
2. The LEDMATRIX_ASSUME_YES=1 environment variable
This is necessary because first_time_install.sh re-executes itself with sudo
if not running as root (line 131), and we need to ensure the non-interactive
flag is preserved through the re-execution.
Also added debug_install.sh diagnostic script to help troubleshoot
installation failures on the Pi.
Recreate one-shot install script that was deleted, with fixes for:
1. APT permission denied errors on /tmp
2. Non-interactive mode support
Fixes:
1. Fix /tmp permissions before running first_time_install.sh:
- chmod 1777 /tmp to ensure APT can write temp files
- Set TMPDIR=/tmp explicitly
- Preserve TMPDIR when using sudo -E
2. Enable non-interactive mode:
- Pass -y flag or LEDMATRIX_ASSUME_YES=1 to first_time_install.sh
- Prevents read prompt failure at line 242 when run via curl | bash
3. Better error handling:
- Temporarily disable errexit to capture exit code
- Re-enable errexit after capturing
- Added fix_tmp_permissions() function
This resolves the 'Permission denied' errors for APT temp files and the
interactive prompt failure when running via pipe.
Fix crash when df produces unexpected output that results in empty
AVAILABLE_SPACE variable, causing 'integer expression expected' error.
Problem:
- df may produce unexpected output format (different locale, unusual
filesystem name spanning lines, or non-standard df implementation)
- While '|| echo "0"' handles pipeline failures, it doesn't trigger if
awk succeeds but produces no output (empty string)
- When AVAILABLE_SPACE is empty, comparison [ "$AVAILABLE_SPACE" -lt 500 ]
fails with 'integer expression expected' error
- With set -e, this causes script to exit unexpectedly
Solution:
- Add AVAILABLE_SPACE=${AVAILABLE_SPACE:-0} before comparison to ensure
variable always has a numeric value (defaults to 0 if empty)
- This gracefully handles edge cases where df/awk produces unexpected output
Address PR review feedback for array-of-objects helpers:
1. Schema resolution: Use getSchemaProperty() instead of manual traversal
- Fixes nested array-of-objects schema lookup (e.g., news.custom_feeds)
- Now properly descends through .properties for nested objects
2. Reindexing: Replace brittle regex with targeted patterns
- Only replace index in bracket notation [0], [1], etc. for names
- Only replace _item_<digits> pattern for IDs (not arbitrary digits)
- Use specific function parameter patterns for onclick handlers
- Prevents corruption of fieldId, pluginId, or other numeric values
3. File upload: Disable widget until properly implemented
- Hide/disable upload button with clear message
- Show existing logos if present but disable upload functionality
- Prevents silent failures when users attempt to upload files
- Added TODO comments for future implementation
Also fixes exit code handling in one-shot-install.sh to properly capture
first_time_install.sh exit status before error trap fires.
- Create comprehensive one-shot installer with robust error handling
- Includes network checks, disk space validation, and retry logic
- Handles existing installations gracefully (idempotent)
- Updates README with quick install command prominently featured
- Manual installation instructions moved to collapsible section
The script provides explicit error messages and never fails silently.
All prerequisites are validated before starting installation.
