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:

options(download.file.method = 'libcurl')

options(url.method='libcurl')

The process is as follow: enter image description here

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!!

The computer you are using to run R on needs to be connected to the internet.

Thanks for answering.

In fact, I can use the computer to install packages by "install.packages()", but the "biocmanager::install()" doesn't work. So I guess it's not a network problem.

I'm really not konw why it's until now.
