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

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

The .debs are from Ubuntu, which is not where I wish to use MC to navigate them.
That's in Mageia, Fedora, and most importantly, openSUSE:
# rpmqa tar
libstartup-notification-1-0-0.12-150400.13.6.x86_64
tar-1.34-150000.3.34.1.x86_64
#

OP was based upon 4.8.31 in openSUSE Leap 15.5. I see a different message in
4.8.30 in 15.4, 4.8.30 in 15.6 (tar 1.34-150000.3.31.1) and 4.8.30 in Slowroll
(tar 1.35-1.1):

	EXTFS virtual file system:
	/usr/lib/mc/extfs.d/uar: line 18: ar: command not found

In Fedora 39, installing dpkg for 4.8.30 is apparently adequate to task, same as
in Tumbleweed (which has tar 1.35-1.2). In Mageia 9 with tar 1.34-5, failing
result is same as in Leap 15.5 (OP).
