Description Paul Eggleton 2016-09-14 22:20:02 UTC

I just started a build with krogoth using a DL_DIR shared with master builds, and was greeted with the following warnings:

------------- snip -------------
WARNING: openssl-native-1.0.2h-r0 do_fetch: Couldn't load checksums from donestamp /media/large/downloads/openssl-1.0.2h.tar.gz.done: ValueError (msg: unsupported pickle protocol: 4)
WARNING: libxml2-2.9.4-r0 do_fetch: Couldn't load checksums from donestamp /media/large/downloads/libxml2-2.9.4.tar.gz.done: ValueError (msg: unsupported pickle protocol: 4)
....
------------- snip -------------

Can we explicitly use an older protocol for this? I would imagine this kind of sharing would be fairly common for people in the transition between older versions and 2.2.

We can specify an older protocol, Maxin already fixed some related issues:

Paul is it possible you have an old stamp from before Maxin's fix landed? I think this is already resolved.

It's quite likely. Thanks!
