ok now I know why wget download has been working while it fails on apt
Problem is the InRelease file being outdated and containing the wrong old size for Packages.xz. Therefore apt is complaining.
Release file created at: Sat, 12 Oct 2024
Also you see the very old date of the Release file from October, while it should be from yesterday.
We disabled the cache for the InRelease files now. In parallel we will check back with Cloudflare community, which reasons can be for cache entries to remain in some edge servers, despite ordering their removal via Cloudflare API.
