I am trying to build a Docker image but when I build it, I get the error message : ‘E: Unable to locate package libxcb-util1’.

Here is my Dockerfile :

`# $DEL_BEGIN`

FROM python:3.9.7-buster
WORKDIR /prod
COPY design_interface design_interface
COPY requirements.txt requirements.txt
COPY setup.py setup.py
RUN pip install --upgrade pip
RUN apt-get update && apt install --assume-yes apt-utils
RUN apt-get update && pip install .
RUN apt-get update && pip install opencv-python
RUN apt-get update && apt install --assume-yes libxcb-icccm4  
RUN apt-get update && apt install --assume-yes libxcb-image0 
RUN apt-get update && apt-get install libxcb-util1
CMD ["python3","design_interface/MainWindow.py"]
`# $DEL_END`

The error message is :

Step 11/12 : RUN apt-get update && apt-get install libxcb-util1
 ---> Running in a6000629d968

E: Unable to locate package libxcb-util1
The command '/bin/sh -c apt-get update && apt-get install libxcb-util1' returned a non-zero code: 100

What is more difficult to understand is why the command line ‘sudo apt-get update && apt-get install libxcb-util1’ works well on my computer but does not work when building the Docker image with the Dockerfile.

    The only solution that I found was to download the file online, and then put it manually in the project repository : design_interface/libxcb-util1_0.4.0-0ubuntu3_amd64.deb.

    Then I added in the dockerfile the line : RUN dpkg -i design_interface/libxcb-util1_0.4.0-0ubuntu3_amd64.deb.

    It worked. :)


  2. According to https://packages.debian.org/search?keywords=libxcb-util1, the package libxcb-util1 exists in bullseye, bookworm, and sid. You are apparently using buster. Buster only has libxcb-util0: https://packages.debian.org/search?keywords=libxcb-util0
