@anirudhacharya : Would you be able to help here?

[aaronmarkham]

Confirming that R installation is broken. Curious why is it fetching an older version (mxnet_1.3.0.tar.gz). Not that newer ones are there. I tried 1.3.1 and 1.4.0 and 1.4.1 and they're not there.

Hi @aashudwivedi - please try it again. I was able to get it to work after downgrading to R v3.5.3, and choosing the USA (IA) mirror... (60).

[piyushghai]

@aashudwivedi Were you able to try it out ?

[ashutosh-dwivedi-e3502]

My apologies for not being able to look at it earlier.
I can confirm that installation completes without any error on this version (3.5.3). Doesn't work for 3.5.2 or 3.6.

Although on trying it out after installation I run into the following error. It's possible that it might have to do something with my own setup. Also this is a fresh installation of R.
