Dear all,
i contact you for an issue I encountered after a little time I didn't
developed/checked packages at work.
The issue I have is from R CMD check:
> tools:::.check_packages()
* using log directory ?/home/l/src/rpkg/lbmisc.Rcheck?
* using R version 3.3.2 (2016-10-31)

... timeout again...
In essence R CMD check became somewhat unusable due to network issues..
I think basically there are download troubles above; I googled a bit
the messages and found they're curl-related. I reproduced them with, say
> download.file('https://cran.r-project.org/manuals.html',
destfile = '/tmp/test.html',
method = 'libcurl')

I think it's a certificate problem (eg CAfile is not none at home) but I
have the certs installed
l at m740n:~$ dpkg -l |grep ca-certificates
ii ca-certificates 20161130 all Common CA
certificates
l at m740n:~$ head /etc/ssl/certs/ca-certificates.crt

Looking at ?download.file i've tried setting manually
CURL_CA_BUNDLE=/etc/ssl/certs/ca-certificates.crt
in .Renviron, but without success

Finally i'm behind a proxy at work but shouldn't be a proxy config
issue since Sys.getenv('https_proxy') and
Sys.getenv('http_proxy') are
set correctly.
So, this goes definitely beyond my troubleshooting abilities; do you
have any hint here?
any thanks, Luca
