I have a password protected zip file which was created in Windows. When I am trying to extract the same file under Ubuntu I get the error need PK compat. v5.1 (can do v4.6). Any idea how to proceed?

According to this thread you can use 7z for this. First install p7zip-full package with:

sudo apt-get install p7zip-full

Then either use the GUI or extract the archive with this command:

7z e /path/to/file


7z x /path/to/file

(second one preserves directory structure).

  • very good that also the GUI (file-roller) understand to use p7zip if installed!

  • This fixed the problem for me. Note that even though this fixes file-roller, the unzip tool will continue to report this error, so you'll have to use 7z for normal zip/unzip.
