Hello!

i am trying to clone the repository but I get this error, I am building in Ubuntu 16.04, this is the docker file:

---

FROM ubuntu:16.04 as builder
RUN apt-get update && apt-get install -y git
RUN git clone --recursive https://github.com/Superhouse/esp-open-rtos.git /opt/esp-open-rtos

---

and I get this:

docker build . -f esp-rtos-dockerfile -t esp-rtos

Same issue here.

Hello @PhilippvK,

as a workaround I fork the project SuperHouse/esp-open-rtos and I delete the folders LVGL from the project, I also delete the the references of this drives in .gitmodules. you can use my repository alejandrogzu/esp-open-rtos to work, it works if you don need lvl drivers.

@maximkulkin do you have any idea what could be happening?

Thank you!!!

@alejandrogzu I found out that the version of Git coming with Ubuntu 16.04 is very outdated. Installing the latest git version resolved the Issue for me.

However, your workaround sounds like a good alternative approach.

If you set to Ubuntu v20.04 as "FROM ubuntu:20.04 as builder" in your docker file, it works perfectly.
