Overview #

During a system update using noid-updater, you may encounter the following error:

E: Repository 'file:/media/local_update_repo bookworm InRelease' changed its 'Origin' value from 'Debian' to 'Relianoid'

This issue prevents the update process from continuing.

Cause #

This behavior is related to a recent metadata change in RELIANOID update repositories.

Specifically, the repository “Origin” label has been updated from Debian to Relianoid.

This change was introduced to more accurately identify update ISOs generated and maintained by the RELIANOID team, instead of inheriting the default Debian origin label.

However, the APT package manager includes a security mechanism that detects changes in repository metadata (such as Origin, Label, or Suite). When such a change is detected, APT blocks updates until the local cache is refreshed, to prevent potential repository spoofing.

Solution #

To resolve the issue, clear the local APT cache so the system can accept the updated repository metadata.

Run the following command:

rm -rf /var/lib/apt/lists/*

Then retry the update process:

noid-updater
noid-updater -i

Explanation #

Removing /var/lib/apt/lists/* forces APT to rebuild its local repository metadata so, on the next update attempt, the system will recognize and accept the new Origin: Relianoid value. This is a one-time action required after the metadata change.

Additional Notes #

This is an expected behavior and not an error in the update itself. No packages or system integrity are affected. The change improves traceability and clarity of RELIANOID-managed update sources.
