[mc] what archive support packages are required to be installed in an rpm distro for mc to navigate .debs as it can with .rpms?

Tue Feb 13 02:34:23 UTC 2024

Yes, Ubuntu-22 does have a modern version of tar, but if I understood the original poster correctly,
the idea was to be able to browse .deb packages (originating from Ubuntu) on an openSUSE machine.
And if so, it's the tar version installed on openSUSE that would matter here...

ubuntu 22 is new enough you should have this feature already:

# grep -w VERSION /etc/os-release
VERSION="22.04.1 LTS (Jammy Jellyfish)"

# tar --help | grep zstd
      --zstd                 filter the archive through zstd

# tar --version
tar (GNU tar) 1.34

I think support for it was added in tar-1.31 - maybe openSUSE has on older version.

  $ tar --help | grep zstd
      --zstd                 filter the archive through zstd

In case you can't or don't want to upgrade to a more recent version for whatever reason, you might
try fiddling with tar's --use-compress-program option, e.g. by writing a wrapper which adds
--use-compress-program=zstd to the list of args tar is being called with if the tarball's name ends
in .tar.zst (and making sure the wrapper is being found before the regular tar program...)

What archive support packages are required to be installed in an rpm distro for mc
to navigate (ubuntu 22.04) .debs as it can with .rpms? My Google-fu isn't doing
very well with this. As it stands, trying to navigate with mc produces:

        ...deb' uses unknown compression for member 'control.tar.zst', giving up
