RCall: internet routines cannot be loaded -> can't install R packages

I have installer RCall making it point to my default R installation on Ubunu.

If I open a R terminal and I install a R package I have no issues, but if I use RCall in Julia like:

R> install.packages('Rcpp', repos='https://cloud.r-project.org/')

I then have the issue:

┌ Warning: RCall.jl: Installing package into ‘/home/lobianco/R/x86_64-pc-linux-gnu-library/4.2’
│ (as ‘lib’ is unspecified)
│ Warning: unable to access index for repository https://cloud.r-project.org/src/contrib:

Any clue on it ?

I was able to solve it by typing:

R"options(download.file.method='wget')"
R"install.packages('ggplot2', repos='https://cloud.r-project.org/')"

(on each session).

Don’t know the reason behind, as people refer to an antivirus effect but it’s not my case…
