When I using "biocmanager", a mistake came. It says "Bioconductor version cannot be validated; no internet connection?"
And warning: Warning messages:
1: In file(con, "r") : InternetOpenUrl failed: 'Unable to establish connection to server '
2: In file(con, "r") : cannot open URL 'http://bioconductor.org/config.yaml': HTTP status was '404 Not Found'
I tried to use this way to solve it, but I failed. The way:

The process is as follow:
So now it's hard for me to install some packages. It's so sad.
Please help me! If you would like help me out, I'll appreciate it a lot!!
