Stop the update if maintenance mode cannot start.
If php artisan down fails, this command continues to replace application files and later runs migrations while the panel can still serve requests. This can expose users to mixed application versions. Abort the update when maintenance mode fails, or require an explicit operator override.

Apply or abort on Git type changes.
A T entry is not handled by the A|M|C*, R*, or D cases, so the path is skipped. The script still sets any_changes=true for the non-empty diff and can update config/app.php to the latest version. The type-changed path can therefore remain stale while the panel reports the new version. Handle T entries or abort before recording the new version.

Do not delete assets until extraction succeeds.
A successful download does not prove that the tarball contains usable public/build files. This code removes the existing build first, then ignores extraction failures. The script still updates config/app.php to the latest version, so a later run can skip recovery while the frontend assets are missing or incomplete.
Extract into a temporary directory. Verify the expected files exist. Replace public/build only after that validation succeeds. Use the Yarn fallback when extraction fails.

Nice direction overall, incremental apply plus the online SQLite backup via sqlite3 .backup and the ERR trap that re-runs artisan up are real improvements over nuke-and-restore.
Requesting changes for three blocking issues (verified against the panel repo): the sort -V pre-release ordering bug that will downgrade installs once v1.0.0 is tagged, the config/app.php canary stamp being conditional on the tarball download, and the 0600 file modes from mktemp. Details with suggested fixes are inline, plus a handful of smaller items.
One doc note that belongs with this PR: incremental updates mean local modifications to files upstream did not touch now survive updates. That is a feature for themes but a support hazard, since "run the updater" no longer guarantees a pristine install. docs/panel/update.mdx should probably say so.

Blocking: sort -V mis-orders pre-release tags, and will downgrade installs once a stable tag exists.
GNU/BSD version sort puts pre-releases after the release: v1.0.0 sorts before v1.0.0-beta38 and v1.0.0-rc1. So the day v1.0.0 is tagged:
all_tags[-1]is still the last beta/rc, solatest_versionis wrong.- A user on a beta never gets
v1.0.0in their upgrade path (it sorts before their current beta, so thefound_currentloop skips it). - A user already on
v1.0.0gets an "upgrade path" of every beta/rc after it, and the script applies those diffs as a downgrade.
The standard fix is the dpkg tilde trick: ~ sorts before the empty string in version sort, so map - to ~ for sorting and back afterwards. Verified: v1.0.0-beta9 < v1.0.0-beta38 < v1.0.0-rc1 < v1.0.0 < v1.0.1.

Blocking: the panel is left reporting version canary whenever this branch is not taken.
In the git tree, config/app.php says 'version' => 'canary' at every tag (the real version is only stamped into the release tarball by CI). So whenever config/app.php changes between two tags, the diff apply above overwrites the installed file with canary. This sed repairs it, but it only runs when the tarball download succeeds. On the yarn fallback path (or a mid-run failure), the panel is left at canary, and the next run of this script normalizes that to vcanary, finds no such tag, and refuses to run at all.
The version stamp needs to happen unconditionally. Remove it from the success branch:
| if [ -f "$backup_dir/$db_database.backup" ]; then | |
| echo "Restoring sqlite database" | |
| cp -a "$backup_dir/$db_database.backup" "$install_dir/database/$db_database" | |

| echo "Failed to restore the database, aborting" | |
| exit 1 | |
| # Update config/app.php version to match the latest release tag (strip leading 'v') | |
| tag_version="${latest_version#v}" | |
| if [ -f "${install_dir}/config/app.php" ]; then | |

| fi | |
| $VERBOSE && echo " [OK ] public/build updated from release tarball." | |
| $VERBOSE && echo " [OK ] public/build updated from release tarball." |
and add it after the fi that closes this if/else (currently line 511), so it runs on both paths:
# Always stamp the release version: the git tree's config/app.php says
# 'canary', and leaving that in place breaks version detection next run.

Blocking: every written file ends up mode 0600.
mktemp creates files with mode 0600 and mv preserves it. The final chmod only covers storage/* and bootstrap/cache, and chown does not touch modes. So every added/modified file loses group/other read and any exec bit, versus the 644/755 the old tarball extraction preserved. That breaks any setup where the web server user is not the file owner (e.g. nginx worker user differing from the php-fpm/file owner).

Should fix: the whole log is passed as a curl argument.
A verbose run over eight version hops can exceed ARG_MAX and make the upload fail exactly when it is most useful. Also, -F gives @ and < special meaning at the start of the value. curl can read the field from the file directly:

Should fix: the error handler never cleans up $tmp_repo.
Each failed run leaves a full bare clone (100MB+) in /tmp.

Related: the plain exit 1 paths (e.g. "current version tag not found", missing sqlite3) bypass the ERR trap, so they never offer the log upload either, which is exactly when you want the log.

Question: what were the skipped files in your sample run?
The PR description shows Skipped: 2, 1, 4, 7, 4 on hops whose diffs contain no protected paths (.env, storage/app/public and the sqlite db are not tracked in git, so they should never appear in a tag-to-tag diff). Every skip here is a file left at the old version with only a WARN that scrolls past.
Suggest collecting skipped paths into an array and printing them in the final summary, so users know what did not update, and it would be good to know what caused these before merging in case it is a systematic extraction failure.

Non-blocking: this hop-by-hop loop is functionally identical to a single git diff $current_version $latest_version apply. Nothing executes at intermediate versions, and migrations/composer run once at the end anyway. The per-version summary is nice UX, but it multiplies the failure surface (and the WARN noise) by the number of hops. If the summary is the only reason for the loop, a comment saying so would stop future readers from assuming intermediate states matter.

Non-blocking: prompt style is inconsistent. This prompt (and the owner/group ones) read from stdin, while later ones use </dev/tty || true. The docs invoke this as sudo bash -c "$(curl -fsSL ...)", so stdin stays a tty and both forms work, but under set -e a stdin-EOF here kills the script while the /dev/tty || true prompts silently take the default. Pick one style for all prompts.

The current method nukes everything, might fail.... Its a mess...
another solution was to apply .patch files... that was also a mess and kept failing due to white space errors...
This will create a backup folder within the pelican folder containing the .env, storage/app/public, and SQLite database ( if used )
Clones the panel repo, then applies the changes from the current users version, to the latest tagged version. Runs migrations, sets permissions. Will extract the build folder from the latest release, and if that fails will attempt to yarn install && yarn build to build them.
If that fails it informs the user that they need to run those commands manually.
