[tex-live] Problems installing TeXlive in CentOS7

[Raimundo Serrano]

Hi Norbert,
I've tried what you suggested. See below what I've got.
Hi Lars, I already have also tried to change the mirrors in the past.
It gave me the same result. I'm in Brazil.
It seems to me that it is indeed the proxy wall which is blocking the
network installer to download the updates; I do not know how to sort
this though.
Thanks again!

Regarding the Norbert's suggestion:
>> You can try running install-tl with -v to get more output.
