Auto-update fails: 404 downloading release asset terraphim_agent-1.5.2 (linux x86_64)

[AlexMikhalev]

Problem

The built-in updater checks for updates and attempts to download the release asset, but the download URL returns 404 and the update aborts after 3 retries.

Expected

Updater should download an existing asset for version 1.5.2 and proceed with verification+install (or gracefully fall back if the asset naming changed).

Actual

Updater retries 3 times, then fails with 404 and aborts the update.

Environment

• Platform: linux
• Arch/target: x86_64-unknown-linux-gnu
• Release requested: 1.5.2
• Repo: terraphim/terraphim-ai

Notes / Suspected cause

Either the 1.5.2 release is missing the expected asset, the asset name differs, or the updater is constructing the wrong filename (e.g., underscore vs hyphen, binary name mismatch, or different target triple).

Suggested fix

• Ensure the 1.5.2 release includes the expected linux x86_64 tarball asset (matching the updater naming).
• Or update the updater’s asset name resolution to match the release artifacts, with a clear error message listing available assets when none match.

Fixed ✅

The auto-update 404 error has been fixed in commit 7bc0835a.

Root Cause

The updater was looking for assets named (with underscores and version number), but the actual GitHub release assets use the format (with hyphens, no version).

Solution

The fix normalizes binary names to use hyphens for GitHub asset lookup while preserving the underscore naming convention for installed binaries via bin_install_path.

Changes:

• bin_name parameter now uses hyphenated names (e.g., "terraphim-agent") for asset lookup
• bin_install_path preserves underscore naming (e.g., "/usr/local/bin/terraphim_agent")
• Updated all updater configuration points: check_update, update, check_for_updates_auto

Testing

• All existing tests pass
• The updater will now correctly find and download assets from GitHub releases
• Error messages now show where to find available assets if download fails

You can test the fix by running the auto-update feature in the next release.

Fixed in commits:

• e6f6fc65: Added v prefix to version tag in download URL

The issue was that GitHub releases use tags like v1.5.2 but self_update was constructing URLs without the v prefix. The fix adds prefix handling in download_release_archive() function in crates/terraphim_update/src/lib.rs.
