Apologies, here are updated build instructions.

export GO111MODULE=on
cd /tmp/
git clone https://github.com/gcla/termshark
cd termshark
git checkout v1.0.0
go install -ldflags="-X github.com/gcla/termshark.Version=1.0.0" ./...

Termshark will not work, unless kali update wireshark to 3.0.2
This is the error I get when I launch it:

Github issue: https://github.com/gcla/termshark/issues/19

As termshark is now in Debian Unstable, we don't need to package it in Kali.
The Debian packages are automatically imported in kali-rolling when they are in Debian Testing.

We don't have wireshark version >= 3 in Kali for the moment. We will import the Debian package version 3.0.2-1~exp0
when it will be available.
Then we can import manually termshark in Kali (the migration to Debian Testing might be long due to the freeze)

Thanks for the information. @j_lito - sorry, I didn't notice that github issue. I'll open it again - I don't believe version 3 of wireshark is necessary. I tested with tshark as old as 1.10.2, and am running happily now myself with 2.6.8. So I think something else might be going wrong when running termshark on your system. I'll ask more questions about that issue on github.

@sbrun - assuming termshark has no dependency on v3 of wireshark, would that change any potential plan for adding termshark to kali linux? Would it still be best to rely on termshark coming for "free" with debian testing -> kali rolling? Thanks!

Sorry @j_jito, I mistyped your username!

@gcla, I replied to the opened issue on your github page.

@gcla I just imported termshark in Kali.
I quickly tested the package and don't reproduce the issue even if wireshark version is lower than 3.*
