unzip message need PK compat. v5.1 (can do v4.6)

[topviet]

I cannot unzip certain zip files. I got this message:
"unzip message need PK compat. v5.1 (can do v4.6)"

What that mean? What should I do to unzip the file?

Thanks.

Welcome!!

Looks like it doesn't like the version you have.

Open System/Admin/Synaptic Package Manager
(you will be asked for your password)

Select Search and type in 'unzip'

Highlight the unzip package and look under Package/Properties for the version number.

Please report back - also report the name of any other specific software you are using to try to unzip.

Unzip version 6.0-1 on Ubuntu 9.10. I tried to unzip my zip file zipped by SecureZip for Windows on Windows XP. I can open my other zip files that zipped by older version of Pkzip.

So - it looks like the problem is you're trying to open a secureZip file and Ubuntu unzip can't do it - although it does support encryption.

SecureZip Express is what you need - it was free but has been withdrawn!

You might have to get back into windows to sort the encryption.

I found a solution: After installed p7zip-full, I can extract my zip file zipped by SecureZIP Express 12.0.

p7zip-full gives you the program "7z"

$ sudo apt-get install 7z

then,

$ 7z e /path/to/file # extracts everything in the archive
