The first two should be compressed:

           INFO     Attachment filename='GNUmakefile.in' mimetype='text/plain'                                                                                                             migrate.py:1717
           INFO     Attachment link https://github.com/sagemath/sage/files/ticket870/GNUmakefile.in                                                                                        migrate.py:1756

And the png files should be attachments instead. - per github contact.

Which step of the migration process do we fix and start again?

[mkoeppe]

Running migrate.py again after fixing the code to make a fresh migration archive. I've already committed a change in the output format (batching json), which our github contact suggested to give a much(?) faster import speed.

[kwankyu]

OK. Thanks.

Done in 830c4f3...bbb7375

Also https://github.com/sagemath/sage/files/ticket9385/dMMCACHEEDGE.LOG is rejected.

[kwankyu]

I don't see anything special about it. It is just a plain text file.
