It seems that the repository for Ubuntu 22.04 (jammy) is not working due to an error in the InRelease file. Iassumethatthis is due to the factthat there are noentriesin the filefor the uncompressedPackagesfilefor the s390xarchitecture. Because of this, apt cannot download the package list and outputs a warning: "W: Skipping acquire of configured file 'main/binary-s390x/Packages' as repository 'https://apt-archive.postgresql.org/pub/repos/apt jammy-pgdg-archive InRelease' does not seem to provide it (sources.list entry misspelt?)". This problem does not appear on other architectures. The issue can be reproduced quite easily. 1. Launch the docker container with the linux/s390x platform 2. Install the necessary packages: apt update && apt install wget gpg -y 3. Add a repository: echo "deb https://apt-archive.postgresql.org/pub/repos/apt jammy-pgdg-archive main" > /etc/apt/sources.list.d/pgdg.list 4. Add a key: wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | apt-key add - 5. Update the package list: apt update After that, a warning will appear.
