What > may be the cause?It looks as though one of your PCs is returning a file in response to the request, rather than signalling that the URL is not found. If you go into a browser like Firefox and try to open the URL http://foo.bar/src/contrib/PACKAGES what do you see on the two systems? I get a message from Firefox that the server is not found. Some ISPs respond to requests for nonexistent URLs with a message, basically an ad for something or other. Maybe that's what you're getting. In any case, this looks like a bug in R: the first request failed, but something got cached, and then the second request got an error reading the cached value. Duncan Murdoch

Dear Duncan, thank you very much, that is it! Indeed, there was activated in my internet router the "telekom navigation help". When I am (or the system is) looking for an not existent url, this "help" opens its own website. After deactivation of telekom navigation help, the normal message (server not found) comes. I never gave attention to this "help", although it is bothering sometimes; now it is switched off in my residence. However, in Germany this problem probably frequently arises, therefor, it should be considered in the respective code for testing R after compilation.
