Error uncompressing .tar.gz file

ulla · Fri Dec 04, 2015 11:33 am

Hi,

I am a new user running Raspbian Jessie (8.0) on a Raspberry Pi 2 B.
Everything seems to be running fine, I can run the applications that came with the Raspbian.

I am trying to install openFrameworks. I used curl -O to download the .tar.gz and as a result I can see the file in the file manager.
But when I try to uncompress it with tar vxfz *.tar.gz I get the following error:
gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now

It seems to me that the .tar.gz file is not recognised as an archive. The file command returns the following information:
HTML document, ASCII text, with CRLF line terminators

Any help would be very much appreciated.

Thanks,
Ulla

You did not download the archive, but an HTML page, possibly the page where the download can be found.

What is the url you are using for the download?

A quick check on teh OpenFrameworks page shows me: http://www.openframeworks.cc/versions/v ... ase.tar.gz for RPi B, B+ (ARMv6) and http://www.openframeworks.cc/versions/v ... ase.tar.gz for 2B (ARMV7)

This is the url:
http://www.openframeworks.cc/versions/v ... ase.tar.gz

Alternative way would be to use wget <url>

Hi hansotten,
Thanks for your reply, but unfortunately this leads to the same error.

Just did a

Code: Select all

wget http://www.openframeworks.cc/versions/v0.9.0/of_v0.9.0_linuxarmv7l_release.tar.gz
tar -xvf of_v0.9.0_linuxarmv7l_release.tar.gz

and is downloaded and unpacked fine.

To be sure, also a curl -O command did get the same file, on which tar did its job.

I am still getting the same error. Could there be something wrong with my operating system?

If it's a HTML file it could be an error page.
Try opening the link in a web browser, or open the downloaded file in a viewer / editor to check its contents.

I have just opened the file with Text Editor, see content below:

With the last few minutes of typing this, I have used Firefox on a Windows PC to click on that URL. It offered a 57 Mbyte download which 7zip has no problem to show as containing 8 folders and 5 files at top level.

So nothing wrong with the URL.

The web-page you got is a page from British Telecom (BT) telling you that it can't find the server "www.openframeforks.com".
Yes FORKS, you typed wrong..

hansotten · Fri Dec 04, 2015 1:59 pm

Its a typing error.

You typed:

http://www.openframeforks.cc/

instead of

http://www.openframeworks.cc/

Edit: sorry topguy, you were faster to post the typing error! Got distracted while entering my reply.

ulla · Fri Dec 04, 2015 2:27 pm

Thanks everyone for your help. I got it to work, by downloading the file via the browser!

About the download resulting in a error via the command line tool, I still do not understand why. I went through this process lots of times and even if I made a spelling mistake once, I certainly did not do so repeatedly.

I'm very happy to have the openFrameworks installer!
Thanks,
Ulla

That puts BT in the "you're a bunch of morons who don't understand networking and DNS" camp. If your DNS fails to resolve an address it should return an NXDOMAIN or SERVFAIL not a stupid web page that redirects to a search engine.

Why don't you offer to show the BT morons the error of their ways for a small reward. Ask them to let you keep the BT Tower.

The Post Office tower isn't that special compared to more modern skyscrapers. I was there three days before the IRA bomb went off and it got closed to the public forever. We were just in the galleries not the revolving restaurant. Dinner on the 42nd floor of the NatWest Tower (now renamed Tower 42) was more of an experience.

At least BTs subsidiary ISP (PlusNet) isn't so brain dead.
