Package: ark
Version: 4:4.10.5-1
Severity: normal

Ark suggests either unrar (non-free) or unrar-free in order to correctly
display and unpack RAR archives. Please note that such suggests is
unversioned.

The version of unrar in Wheezy was 1:4.1.4-1 and it worked quite well.

In Jessie, however, unrar transitioned from the 4.x series to the 5.x
series. In the transition, the output format *drastically* changed,
and Ark cannot deal with it anymore.

This is an example of the output of unrar 4.x, with its typical 'tabular'
style (which, by the way, is very similar to the output of unrar-free). I
invoked unrar with the same options as used by Ark itself. The text spans
79 columns, I hope it doesn't get wrapped by some mail processing.

On the other hand, this is the output of unrar 5.x when invoked on the
same archive and with the same options:

In both cases I cut the output after the first 5 items, as they should be
enough to show the point.

I don't think that the issue can be solved hacking at the
dependency level, using e.g. versioned suggests: unrar and unrar-free are
managed through the alternatives framework, so there is no guarantee of
which version the user has configured.

Instead, the issue should probably be forwarded upstream, and solved by a
major rewrite of the parser in Ark (and the new parser should be so smart
as to tell apart the three formats: unrar 5.x, unrar 4.x and unrar-free).

Hi,

The issue was fixed upstream, tagging later versions as fixed.

Happy hacking,
