All metar fetches fail due to NOAA 302 redirect

[Peter Frost]

[Impact]

 * NOAA changed the URL for the service metar relies on to retrieve weather information
 * This has been fixed in 20061030.1-2.2 that is in YY and ZZ (LP: #1610210)
   but not yet in XX (16.04 LTS) and previous releases
 * justification: the metar program will not display any weather information
   anymore without the fix (complete functionality loss for users)
 * remedy: update URL in the source (it is hardcoded)
   (a work-around is to set the environment variable to the new URL
    METARURL=http://tgftp.nws.noaa.gov/data/observations/metar/stations)

[Test Case]

 * install metar # 20061030.1-2ubuntu2
 * metar FACT # metar information for Cape Town Airport (CPT)
   -> METAR pattern not found in NOAA data
   (correct would be something like: FACT 251000Z 18020KT CAVOK 22/13 Q1017 NOSIG)

[Regression Potential]

 * just a hardcoded URL fix, no program change otherwise
 * works in Debian sid & testing, Ubuntu YY and ZZ

[Other Info]

 * Stable upload in progress as well for next Debian Jessie point-release

-----------------------------------------------------------------------------

All metar fetches are failing:

$ metar LSZH
METAR pattern not found in NOAA data.

Requests for http://weather.noaa.gov/pub/data/observations/metar/stations/XXXX.TXT are now receiving a 302 redirect to http://tgftp.nws.noaa.gov/data/observations/metar/stations/XXXX.TXT

metar needs an updated METARURL, or to set CURLOPT_FOLLOWLOCATION

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

btw: I stress for a *international*, *independent*, *non-US* solution reference here.

[Peter Frost (k-4eter-a)]

For a workaround, metar checks the METARURL environment variable:

METARURL=http://tgftp.nws.noaa.gov/data/observations/metar/stations metar LSZH
LSZH 261320Z 03008KT 9999 SCT036 21/12 Q1020 NOSIG

This bug was fixed in the package metar - 20061030.1-2.2

---------------
metar (20061030.1-2.2) unstable; urgency=medium

  * Non-maintainer upload.
  * Import patch for new METAR URL from Kees Leune. Closes: #833655
