thanks!

A few points:

• I don't use CentOS, so can't assess this, but I am surprised that it is necessary. We use libsodium through PyNaCl, which ships with a copy of the libsodium sources, which gets built on installation. I have a suspicion that it wasn't installing libsodium itself which fixed things for you, but something else which got installed as a side-effect of installing libsodium.
• I would expect that upgrading pip made upgrading setuptools redundant.
• We need signoff, per https://github.com/matrix-org/synapse/blob/master/CONTRIBUTING.rst#sign-off.

You are right with the first part. libsodium is not needed as a system requirement on CentOS. My problem was that it crashed during the setuptools upgrade so I had to install libsodium to make it works. But when I do proper upgrade, e.g. I upgrade pip first, than setuptools upgrade does not crash and PyNaCl build without problems.

However with the second bit it doesnt upgrade both at the same time. I have to upgrade pip as it doesnt upgrade setuptools, here is an output from my command line:

Ok, great, thanks very much for your investigative work. I'm afraid I still need signoff on the original commits (sigh). Can you write a signed-off-by here?

[ricco386]

Sure no problem.
