Error occurred when installing JuNest

So looks like my tar is missing the z option which you're using to extract a .tar.gz
One workaround would be to replace the -z with an equivalent gzip command, which is available to me.
Is it an option to try that in case straight tar fails?

Hi,

can you check whether gzip is installed in busy box? an alternative could be to run gzip and then tar commands. This would be more generic approach, I guess.

Also, does junest runs well in busybox can you try it?

I'm trying to install JuNest on a Batocera machine. It was a method recommended in this reddit post I made about adding packages.

Not sure why, but others seem to have the -z option, while for some reason mine does not seem to.

gzip is available though with the following options

Usage: gzip [-cfkdt] [FILE]...

Compress FILEs (or stdin)

	-d	Decompress
	-c	Write to stdout
	-f	Force
	-k	Keep input files
	-t	Test integrity

and BusyBox is v1.35.0, but I can't confirm JuNest works well until I complete the install

I will change the script to include gzip command. In the meantime you can try it by changing this line here: https://github.com/fsquillace/junest/blob/master/lib/core/setup.sh#L55

Given I do not have busybox, can you try modify that line and tell what is the working commands? Also, I am afraid that constructing general commands might be hard given that tar in busybox accepts a x to extract file whereas in other linux systems is -x.
