Package: www.debian.org
On the packages.d.o pages of arch:all packages from sid, bullseye or
experimental, the "list of files" link gives the error message "No such
package in this suite on this architecture."
This does not affect arch:any packages, or packages from stable.
e.g.
fails - https://packages.debian.org/sid/all/python3-pandas/filelist
OK - https://packages.debian.org/buster/all/python3-pandas/filelist
OK - https://packages.debian.org/sid/amd64/python3-pandas-lib/filelist
Possible cause: these suites have a separate Contents-all.gz file, but
https://salsa.debian.org/webmaster-team/packages/-/blob/master/bin/parse-contents#L178
appears to assume there isn't and try to use
Contents-${last_arch_checked}.gz.
