Ubuntu – Extracting a password protected .7z file with ‘p7zip’ returns an error

7zipextract

I am trying to extract a password protected .7z file with p7zip -d filename.7z command. Unlike on Windows, on Ubuntu I do not get a prompt to enter password. Instead the terminal throws an E_NOTIMPL error. Could it be that the file is corrupted? Or am I doing it wrong?

There is a known bug/limitation in p7zip, in which it cannot work with password-protected encrypted files (technically by design as a 'lighter' kind of 7zip), and throws the error you've stated here when it tries to work with them.

The correct approach for encrypted/passwords 7z files is to use p7zip-full instead of p7zip, which should then work as it should.

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).
