Hello
The PoolFileOverwriteError in the publish-ftpmaster.py script occurs when there’s an attempt to overwrite a file in the pool directory with a different file, indicated by mismatched SHA1 checksums. This usually happens when an existing package version is re-uploaded with modified contents. To resolve this, ensure that uploaded files have unique versions or verify the SHA1 of the uploaded file matches the current pool file to avoid unintentional overwrites.

Hello,

You are dealing with an error related to publishing a file in a system, possibly related to a Launchpad repository or an internal publishing pipeline. The specific error you're encountering is a PoolFileOverwriteError, which typically occurs when there’s a conflict between the file you're trying to add and an existing one, identified by different checksums (sha1 values).

Breakdown of the Error
Error Type: PoolFileOverwriteError

This error occurs when there’s an attempt to overwrite an existing file in the repository or disk pool with a file that has a different checksum.

Conflict:

The error message indicates a mismatch between two checksums:

92c921c793d4f95ec628f28ecb98cfdac50b61c7 (the current file’s checksum)

f6dd336dab9bd75d34ceefcb8bdfaf0348b51f2d (the checksum of the file you're trying to add)

The conflict arises with the file /srv/launchpad.net/ubuntu-archive/ubuntu/pool/main/l/language-pack-kde-ru/language-pack-kde-ru_12.04+20120130_all.deb.

Traceback:

The error propagates through several Python modules: lp.soyuz.model.publishing, lp.archivepublisher.diskpool, and processaccepted script, which is part of a publishing pipeline.

Possible Causes
File Mismatch:

The file you are attempting to publish seems to have been previously added to the system (or repository), but there’s a mismatch in its content or checksum.

Duplicate File:

The system may be trying to overwrite a file in the pool with a file that has a different checksum or data integrity issue.

Checksum Calculation Issue:

There could be an issue with how the checksums are calculated or stored in the repository, potentially due to a bug or misconfiguration in the publishing pipeline.

Suggestions to Fix the Issue
Verify the File:

Check the file contents at /srv/launchpad.net/ubuntu-archive/ubuntu/pool/main/l/language-pack-kde-ru/language-pack-kde-ru_12.04+20120130_all.deb to see if it’s indeed different from the version being uploaded.

Confirm if the new file is intentionally different or if it should be the same as the existing one. If the file has changed, this could be an expected result.

Clear or Replace the Conflicting File:

If the file should be updated or replaced, you may need to manually remove the old version from the disk pool or repository and then attempt the publish again.

Check Checksum Calculation:

Ensure that the process used to calculate the file’s checksum is correct. There may be an issue where the file has been corrupted, or the checksum was incorrectly calculated in a previous step.

Ensure Proper File Handling in publish-ftpmaster.py:

Investigate the publish-ftpmaster.py script and see how it handles file overwriting or checksum verification. You may need to adjust the script to handle these conflicts more gracefully, either by skipping files with mismatched checksums or ensuring the correct file version http://www.ez-passma.com is used.
