How to Rebuild Missing Joomla Extension Update Sites
Prefer Joomla's recovery tools
Do not invent update-site database rows. Start at System → Update → Update Sites so recovery is based on installed extension information.
Back up first
Take a current database backup before repairing extension-management metadata.
Confirm the source is actually missing
Search for the extension and clear filters. A source may be disabled rather than absent.
Use Rebuild when available
Use the Update Sites toolbar Rebuild action. Joomla reconstructs update-site associations from update-server information declared by installed extensions.
Know Rebuild's limit
Rebuild cannot create a source an installed extension does not declare. Older products or proprietary updaters may have no Joomla update-server declaration.
Check the manifest and vendor
Confirm the installed version is supposed to register an update server. If the manifest is damaged or obsolete, use the developer's supported package or repair path.
Refresh afterward
Return to System → Update → Extensions, clear stale update information if needed, then run Find Updates.
