Cannot build Docker image : unable to install tini

[Toctave]

Hi! When trying to build the docker image on a Ubuntu 22.04 machine, I get the following logs :

Step 10/19 : RUN apt-get install -y curl grep sed dpkg &&     TINI_VERSION=`curl https://github.com/krallin/tini/releases/latest | grep -o "/v.*\"" | sed 's:^..\(.*\).$:\1:'` &&     curl -L "https://github.com/krallin/tini/releases/download/v${TINI_VERSION}/tini_${TINI_VERSION}.deb" > tini.deb &&     dpkg -i tini.deb &&     rm tini.deb &&     apt-get clean &&     rm -rf /var/lib/apt/lists/*

The command '/bin/sh -c apt-get install -y curl grep sed dpkg &&     TINI_VERSION=`curl https://github.com/krallin/tini/releases/latest | grep -o "/v.*\"" | sed 's:^..\(.*\).$:\1:'` &&     curl -L "https://github.com/krallin/tini/releases/download/v${TINI_VERSION}/tini_${TINI_VERSION}.deb" > tini.deb &&     dpkg -i tini.deb &&     rm tini.deb &&     apt-get clean &&     rm -rf /var/lib/apt/lists/*' returned a non-zero code: 1

The issue seems to be that the curl command that sets TINI_VERSION doesn't work. At least on my machine, running curl https://github.com/krallin/tini/releases/latest does not return anything.

I pushed the fix, please give it a try

That worked, thanks. However there was another issue when trying to run the container, I'll open a new thread.
