Oops! Here are the resulting error messages, which are not the same:
> ap1 <- available.packages(repos = "http://foo.bar")
Warning: Cannot access to the index of the repository
http://foo.bar/src/contrib:
  line beginning with '<!DOCTYPE html PUBLI ...' is incorrect formatted

> ap2 <- available.packages(repos = "http://foo.bar")
Error in readRDS(dest) : unknown input format

On my other PC, the same lines give 2 times the same error message:
"Warning: Cannot access to the index of the repository
http://foo.bar/src/contrib: Cannot open URL
'http://foo.bar/src/contrib/PACKAGES' "

Indeed, the second error message on the present PC is different. What
may be the cause?

Many thanks
