Until a recent reinstall of 16.04 I was able to extract encrypted .enz files (made with Cobian in Windows) with the Ubuntu archive manager. Now, following the reinstall, archive manager chokes on the encryption password with the message, "An error occurred while extracting files." I know the password I am using is correct because it works on the same file opened with Cobian Decompressor in Windows. Any suggestions about what might get me back to being able to open these files in Ubuntu (that does not involve wine)?
FIXED! The answer is the full 7zip.
sudo apt install p7zip-full
did the trick. See [https://www.ibm.com/developerworks/community/blogs/6e6f6d1b-95c3-46df-8a26-b7efd8ee4b57/entry/how_to_use_7zip_on_linux_command_line144?lang=en] is where I got the idea to try this.
