Draft: [REF] common: Fix tcl dependency for unbuffer

Moisés López | ❖ Vauxoo - https://www.vauxoo.com/ requested to merge vauxoo-dev/gitlab_tools:fix-unbuffer-moy into master

Unbuffer requires 2 dependencies:

  • expect-dev
  • tcl8.6

Generally it is installed but there are images where it is not installed

e.g. quay.io/vauxoo/absa:absa-12.0-latest

Steps to reproduce:

docker run -it --rm quay.io/vauxoo/absa:absa-12.0-latest /bin/bash -c "apt update -qq && apt install expect-dev && unbuffer"

Output: /usr/bin/unbuffer: 4: exec: tclsh8.6: not found

But running: docker run -it --rm quay.io/vauxoo/absa:absa-12.0-latest /bin/bash -c "apt update -qq && apt install expect-dev tcl8.6 && unbuffer"

It is running fine

Installing tcl8.6 is compatible with newer images too e.g. absa-15.0

docker run -it --rm quay.io/vauxoo/absa:absa-15.0-latest /bin/bash -c "apt update -qq && apt install expect-dev tcl8.6 && unbuffer"

It is running successfully

So, it looks safe to do it in this way
