I downloaded the "Anaconda-2.4.2-Linux-x86_64.sh" from its website,
but when I wanted to install it by putting
"bash Anaconda-2.4.2-Linux-x86_64.sh" in the terminal,
it failed and told me
"ERROR:the size of Anaconda-2.4.2-Linux-x86_64.sh should be 467689464 bytes".
I had tried google, but there is no answer.
Just download again the file Anaconda2-4.2.0-Linux-x86_64.sh as indicated by @furas
The size of the file have to be: 467689464 bytes
And just press Enter to install:
