Tried install_github("hfgolino/EGA", dep = TRUE) getting error "Installation failed: SSLRead() return error -9806"


I used the above code (install_github("hfgolino/EGA", dep = TRUE) but got the following warning:

Installation failed: SSLRead() return error -9806

I repeatedly tried to upload the EGA package but didn't succeed; would you help me with that?

Ty very much!

This sounds like a curl problem, do you have the latest versions of curl and httr packages? If not, try updating them first.

Also, is your internet connection behind a proxy server or firewall?

I upgraded curl and httr packages but the problem remains: in fact, the whole message I receive is as follows:

Downloading GitHub repo hfgolino/EGA@master

  • installing source package ‘EGA’ ...

    Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) :

As far as I know, the proxy server is not blocking any service in R...but, how can I be sure of that?

Thanks a lot :slight_smile:

This is a completely different error, now your problem is that you have to update dplyr before installing EGA


Also, you are using a fairly old version of R, if you update to the latest version (3.5.2) you'll have access to precompiled binaries which will make the installation process for several packages faster and simpler.

Wow, I tried it before posting my doubts and it didnt work - but now it did! I upgraded the "dyplr" package and the "EGA".

Thanks a lot :slight_smile:
