Paramfetch does not work

When I run ./paramfetch -a, it reports
8 parameter files failed to be fetched:

fatal error: some parameter files failed to be fetched. try again, or run paramcache to generate locally

Then I run
./paramcache
It was killed after sometime.

I thought ./paramfetch was using the ipfs network, so I ran ./ipfs daemon, but it did not help.

Could anybody help on this?

We just did a new release as of today (0.2.4). I have been able to run paramfetch successfully a few times today. Can you please try paramfetch again?

Unfortunately still the same error. Btw, do I need to run “ipfs daemon” first?

No you should not need to run ipfs daemon first. Paramfetch should take care of all of that. You downloaded the binary, is that right? What OS are you running on?

Yes I downloaded it from https://github.com/filecoin-project/go-filecoin/releases
The OS is Ubuntu 16.04.5 64bit.
