Invalid tar magic
 

I always get a "invalid tar magic" when i try to decompress an archive.
the way i use the tar is: tar zxvf archive_name

And the archives are not rar files, as i've seen in another thread on this forum. Anybody has any clue? I even installed tar again on another folder and used it (actually i've used the tar installed when i've modified the N770 for dual boot).

Having this problem too (trying to install a monome emulator http://monome.org/ ).

I guess I'll have to try untar-ing it on my Mac, zip it up and send back to the Nokia...

Also, following the instructions on the monome site, they say to use the switches xjvf but tar on the 770 doesn't understand the j option...

I guess the 770 must have quite an old or non-standard wget?

Re: Invalid tar magic
 

The "j" option is for bzip files, which the tar on the 800 (or 770) does not understand. If you re-zip the file as a .gz and then use the "zxvf" option, it should work.

You're right, it was a .bz2 - cheers for explaining what was going on with that one :)

(yeah I meant tar, not wget :rolleyes: )

I have the same problem on my N810:
Edit: I've tried the 5 formats (gnu, oldgnu, v7, ustar and posix) handled by GNU tar to create the archive and get this error in every case. The gmp-4.2.2.tar.gz archive can be untar'ed.

Any idea?

Edit: I've reported a bug: BusyBox v1.6.1 has broken tar.

Re: Invalid tar magic
 

I just want to bump this because I am also having this problem - I can't untar any file on my N810, but I can untar them just fine on a normal Ubuntu box.

Has anyone solved this?

Re: Invalid tar magic
 

For me, tar.gz = tar zxvf
tar.bz2 = tar jxvf
tar = tar xvf

Of course, add xarchiver repo and grab bzip2 and gnutar incase :)

Re: Invalid tar magic
 

Aha, well tar still doesn't work, but I installed gnutar and it gets the job done. :)

Thanks.

a) If you don't have GNU tar, just use 'bunzip -c file.tar.bz2 | tar tvf -' (or xvf -). Obviously you still need bzip2 installed.

b) The file name may be incorrect. Use 'file mystical.fiilename.strange.extension' and see what it tells you. It should be able to identify it as e.g. a gzipped file, or just a plain tar file, for example.
