Hi Ralf,
$ sudo pacman -U https://mex.mirror.pkgbuild.com/community-testing/os/x86_64/lxpanel-0.10.0-1... error: failed retrieving file 'lxpanel-0.10.0-1-x86_64.pkg.tar.xz' from mex.mirror.pkgbuild.com : Resolving timed out after 10000 milliseconds
I think you're on the wrong track by suspecting iana-etc. It's probably more likely to be a DNS, web proxy, or IPv4/IPv6 issue. You could try sudo -i pacman -v --debug -U https://mex.mirror.pkgbuild.com/community-testing/os/x86_64/lxpanel-0.10.0-1... to see if the extra output helps, but I suspect it won't. Does the curl library take note of environment variables to produce debug? I don't know. So I'd reach for strace, given ltrace(1)'s apparent brokenness. sudo -i env LC_ALL=C strace -fe %net pacman -U https://mex... That way you can see the connect(3), etc., and the IP addresses involved, plus what errors occurred. -- Cheers, Ralph.
