Unzip: skipping filename.zip need PK compat. v4.6 (can do v2.1)

Ocak 25

Sometimes extracting a zip file using the unzip command may result in the “skipping: filename.zip  need PK compat. v4.5″ error message.

# unzip filename.zip
Archive:  filename.zip
   skipping: filename.zip  need PK compat. v4.6 (can do v2.1)

This is due to the file been compressed with the latest version of PKZIP which the unzip command cannot handle. The solution is to install p7zip package which can handle the files compressed using PKZIP.

Download the latest version of p7zip:

# wget http://downloads.sourceforge.net/project/p7zip/p7zip/9.20.1/p7zip_9.20.1_x86_linux_bin.tar.bz2?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fp7zip%2Ffiles%2Fp7zip%2F9.20.1%2Fp7zip_9.20.1_x86_linux_bin.tar.bz2%2Fdownload&ts=1390605043&use_mirror=garr

Extract the file

# tar -jxf p7zip_9.20.1_x86_linux_bin.tar.bz2

goto the extracted directory and run the installer

# ./install.sh

This will install the ’7za’ command on your server using which the zip file can be extracted

# 7za x filename.zip
 Processing archive: filename.zip
 Extracting  filename
 Everything is Ok
