A General-tab toggle (off by default) checks for and installs LEDMatrix and plugin updates once a week, overnight in the configured timezone. - Pre-update checks skip (and report) instead of forcing: local edits or commits, merge/live rebase, no upstream, low disk, missing health check, or a version that was already rolled back. An abandoned rebase (HEAD back on a branch) is cleared, since it would otherwise block every pull. - The pull reuses the Update Code path (now perform_core_update(), which reports dependency install failures as data). - ledmatrix-update-verify.service, started via a .path unit from a request file, restarts the services from its own cgroup, requires them to come up and stay up, and otherwise resets to the previous commit and reinstalls the previous requirements. It runs a copy of the checker taken before the pull. - No SSH needed: switching the toggle on restarts the display service, which (as root) installs the two units from the repo templates for the web user. first_time_install.sh installs them too and takes --enable-auto-update / LEDMATRIX_AUTO_UPDATE (passed through by one-shot-install.sh). - Plugins update after the code passes its check; failures, blocks and rollbacks raise an Overview banner and show under the toggle. Tested end to end on a Pi: web-UI setup, a good update, a broken web service and a broken display (both rolled back), a blocked local edit, and an abandoned rebase found on the device.

# This is a template. Do not install it directly -- run

# scripts/install/install_web_service.sh (or install_service.sh); the display
|
|
# service also installs it when automatic updates are turned on
|
|
# (src/auto_update_setup.py). Substitutes:
|
|
# __PROJECT_ROOT_DIR__ -> the directory the project is installed in
|
|
# __USER__ -> the user the web interface runs as
|
|
#
|
|
# Health check and rollback for the web interface's weekly automatic update
|
|
# (web_interface/auto_update.py). A separate unit because the check restarts
|
|
# ledmatrix-web.service, which would kill it if it ran there.

|
|
# Never enabled itself: ledmatrix-update-verify.path starts it when the web

|
# interface creates data/auto_update_verify.request. It runs as the web
|
|
# interface's own user, and ExecStart points at the copy the updater makes
|
|
# before pulling, so the update being checked cannot replace its checker.
