[PATCH opkg 0/5] Purge packages from cache when they have incorrect checksum

[Baptiste Jonglez]

Hi,

Any news on this patch series?  It should definitely be considered
before the 20.XX branching because it fixes FS#2690 (bug related to
imagebuilder), and I would like to backport it to 19.07 at some point.

Thanks,
Baptiste
