Hi everyone,
I’m experiencing an issue while building my Docker images using Alpine 3.19. The build fails during the installation of system packages, with the following error messages:
WARNING: fetching https://dl-cdn.alpinelinux.org/alpine/v3.19/main: temporary error (try again later)
ERROR: unable to select packages:
g++ (no such package):
required by: world[g++]
libffi-dev (no such package):
required by: world[libffi-dev]
make (no such package):
required by: world[make]
python3-dev (no such package):
required by: world[python3-dev]
Here are the relevant parts of my Dockerfiles for both the web server and worker:
# Build image
FROM python:3.11-alpine3.19 AS build
# Other instructions...
ARG PACKAGES='\
g++ make python3-dev \
libffi-dev \
'
RUN echo "Install system packages" && \
apk add --no-cache $PACKAGES
# Production image
FROM python:3.11-alpine3.19
ARG RUNTIME_PACKAGES='\
dumb-init \
'
RUN echo "Install runtime packages" && \
apk update && \
apk add --no-cache $RUNTIME_PACKAGES
Things I’ve tried:
Retrying the build multiple times in case it was a temporary network issue.
Questions:
Has anyone encountered a similar issue?
Is there a recommended approach to ensure successful package installation in Alpine-based Docker images?
Any help or insights would be greatly appreciated!
Thank you!

I just built the dockerfile snippet you added, it worked fine…

When I run ktd --debug up in the repository, it throws me this(the whole traceback):

Since @deanayalon is able to build the image, you are most likely affected by a network problem:
either on your host or in your local network
the regional cdn endpoint for dl-cdn.alpinelinux.org you get connected to
somewhere between your local network and the cdn endpoint.
