Alpine Linux Docker Image – Installing libnsl

I am using Alpine Linux 3.18
My base image is gradle:7.6.1-jdk17-alpine

 RUN export ALPINE_VERSION=$(cat /etc/alpine-release | cut -d "." -f 1-2) && ` rm /etc/apk/repositories &&  
 echo "@main local_nexus/repository/alpine-proxy/v$ALPINE_VERSION/main" > /etc/apk/repositories &&  
 echo "@community local_nexus/repository/alpine-proxy/v$ALPINE_VERSION/community" >> /etc/apk/repositories
    
  # Install build tools
  RUN apk add --no-cache 
      git@main 
      docker-cli@community 
      curl@main 
      libaio@main 
      libc6-compat@main 
      libnsl@community && 
      rm -rf /var/cache/apk/*

I am getting following error.

ERROR: unable to select packages:
  libtirpc-conf-1.3.3-r2:

  libtirpc-1.3.3-r2:
    masked in: @main
    satisfies: libnsl-2.0.0-r0[so:libtirpc.so.3]

To install packages, I am using a corporate Nexus proxy URL which points to Alpine package repository. Other packages get installed without any complain which means there is no issue with the connectivity / certificates.

Any suggestions please

libnsl depends on 3 packages
https://pkgs.alpinelinux.org/package/v3.18/community/x86/libnsl
One of them is libtripc, which depends on libtirpc-conf
https://pkgs.alpinelinux.org/package/v3.18/main/x86/libtirpc-conf

    Work around if you want to keep the @main and @community, is to install the dependant packages manually.

      libaio@main 
  libc6-compat@main 
  libintl@main 
  libtirpc@main 
  musl@main 
  libnsl@community

    libnsl is in community but its dependant packages are in main, when you provide the package name as libnsl@community it cannot find the dependant packages in main This is what I suspect, I could be wrong.

    FROM gradle:7.6.1-jdk17-alpine

RUN export ALPINE_VERSION=$(cat /etc/alpine-release | cut -d "." -f 1-2) && 
    rm /etc/apk/repositories && 
    echo "https://dl-cdn.alpinelinux.org/alpine/v$ALPINE_VERSION/main" > /etc/apk/repositories && 
    echo "https://dl-cdn.alpinelinux.org/alpine/v$ALPINE_VERSION/community" >> /etc/apk/repositories

RUN apk add --no-cache 
        git 
        docker-cli 
        curl 
        libaio 
        libc6-compat 
        libnsl && 
    rm -rf /var/cache/apk/*

    You don’t need to specify the main and community repositories when installing the packages.

    I believe that the issue with your approach arises from the @main and @community at the beginning of the lines you are inserting into /etc/apk/repositories. Remove those and the packages should install.

    Since I don’t have access to your proxy repositories, that’s impossible to test.
