MC (Midnight Commander) does not wish to work with zip archives

Same issue here.
MC doesn't list any zip-related package (.zip, .jar) .

MC doesn't work with unzip 6.0-1.
Unzip 5.x from Jaunty work ok.

Workaround for unzip is setting $op_has_zipinfo=1 in /usr/share/mc/extfs/uzip
Used SW: Ubuntu 9.10, mc 4.6.2, unzip 6.0

@Jaromir Obr: Thanks for the workaround! I'm wondering why it was set to 0 if the recommended value is 1.

Jaromir Obr: thanx too

The fix is working, thanks !

Works also for me. Thanks.

Hi:

The actual fix requires changing the regex that parses the output of 'unzip -qq -v' (which has changed), as well as the code that uses the results of that regex. Here's the diff:

Please let me know if this needs to be submitted in some other way.

Why don't you backport the fixed package into Karmic? This fix is really needed and for now workaround needs to be done of every machine it's installed...

In Karmic the patches posted here are not enough (I haven't tested Lucid package).
There's a problem with directories inside zip archives.
The files are listed in mc like:
| Directory\File.txt | 10 | 01.01.2008 |
and files could not be opened because of bad directory and file separator "\" where it should be "/".

Is it will be patch for 9.10 ubuntu or not?

Its very annoying that I can't list archive zip files content directly from mc.... Its simple neeeded for me and I think for many users which suprisingly see lack of this simple mc feature..

No fix will be released for Ubuntu 9.10. If you need backports from Debian unstable use my unofficial PPA.

Hi Yury! I've just installed mc from your PPA tested and it's fixes my problem. Thanks! :-)

Hi,

Ben Okopniks changes work for me too.

Thanks
Lars
