This seems like a connectivity issue, R is not being able to connect to the CRAN repository you have selected, these are some things to try.

• Choose a different CRAN repository, RStudios repository is a good choice (http://cran.rstudio.com/) or you could choose one that is geographically closer to you.
  
  
• Disable secure download setting.
  
  
• Check if your internet connection has traffic restrictions of some kind, like a firewall, proxy server, etc. This is usually the case when you are at work or school.

no, this advice doesn't work for me. arning in install.packages :
package ‘timek’ is not available (for R version 4.0.1)

After upgrading to 4.0 and now 4.0.1 I can't install loads of packages. The mirror site isnt' the issue, I hope this issue gets solved fast.

Run with secure connection, it will work

@ankeR

package ‘timek’ is not available (for R version 4.0.1)

this issue is likely a typo.
timetk is a package available on CRAN, and timek is not.
