Unpacking recent ace archives in Ubuntu

Tue, 07/21/2009 - 13:33

There are two different versions of the unace package on Ubuntu. The standard version is fully open source but dates from 1999 and can not unpack recent ace archives.

If it encounters a more recent archive you will get errors like:
File compressed with unknown method. Decompression not possible.
an error occurred while extracting

The solution is to install the linux unace-nonfree binary that is supplied by ACE Compression Software. It is not open source but it will work fine. You can install it using Synaptic or with the following command:
sudo apt-get install unace-nonfree

To unpack an archive with this version, just use the unace command:
unace x filename.ace
