[R-pkg-team] Bug#976059: Migrate to udd-mirror.debian.net hostname

[Andreas Tille]

Hi Asheesh,

thanks a lot for your quick and helpful response.  Meanwhile I've read
the Wiki about the public UDD mirror.  This has mentioned that for
"older" psql versions the old method needs to be used.  I wanted to stay
on the save side and reverted to the old method but the new mirror /
user / password settings.  This helped and while not beeing as elegant
ist might work more reliably on different systems.

I'll keep your fixes in mind and your analysis is correcht:

$ echo $PGPORT
5452

which I have set on my local machine which I've used.

Thanks a lot for maintaining the UDD mirror which is really helpful

     Andreas.
