I am trying to build and deploy microservices images to a single-node Kubernetes cluster running on my development machine using minikube. I am using the cloud-native microservices demo application Online Boutique by Google to understand the use of technologies like Kubernetes, Istio etc.

Link to github repo: microservices-demo

While following the installation process, and on running command skaffold run to build and deploy my application, I get some errors:

Step 10/11 : RUN apt-get -qq update     && apt-get install -y --no-install-recommends         curl

I receive these errors when trying to build loadgenerator.
How can I resolve this issue?

  1. There are a few reasons why you encounter these errors:

    1. There might be an issue with the existing cache and/or disc space. In order to fix it you need to clear the APT cache by executing: sudo apt-get clean and sudo apt-get update.

    2. The same goes with existing docker images. Execute: docker image prune -f and docker container prune -f in order to remove unused data and free disc space.

    3. If you don’t care about the security risks, you can try to run the apt-get command with the --allow-unauthenticated or --allow-insecure-repositories flag. According to the docs:

    Ignore if packages can’t be authenticated and don’t prompt about it.
    This can be useful while working with local repositories, but is a
    huge security risk if data authenticity isn’t ensured in another way
    by the user itself.

    Please let me know if that helped.

  2. I think that is related to some LSM component of the docker official image (in this case armhf) and exec/capabilities permissions. In this simple case sid flavour is unable to handle time corectly. And this related to the certificate check, is the cause of invalid signature. It happends too in ubuntu focal.

    # docker run -it debian:buster /bin/date
    Sun Nov 15 11:30:44 UTC 2020
    # docker run -it debian:sid /bin/date

  3. The reason I usually see this is because docker has run out of disk space, which is frustrating because the error gives little indication that this is the problem. First try cleaning up images and containers you don’t need using the prune command https://docs.docker.com/config/pruning/.

    $ docker image prune 
    $ docker container prune 
    

    If you have a lot of images accumulated and want to remove all of them that aren’t associated with an existing container try:

    $ docker image prune -a 
    

    Or you can remove only older images:

    $ docker image prune -a --filter "until=24h"
    

    Finally, on MacOS, where Docker runs inside a dedicated VM, you may need to increase the disk available to Docker from the Docker Desktop application (Settings -> Resources -> Advanced -> Disk image size).

  4. I had this same issue and none of the previous responses saying to prune images or containers worked. The reason was that my Docker Build Cache was taking up the bulk of the space. Running the below command fixed the issue:

    docker system prune
    

    You can then check to see if it worked by running:

    docker system df
    

    UPDATE:

    The above command will clear the whole Docker system. If you want to clear only the build cache, you can do it with the below command (credit to saraf.gahl):

    docker builder prune

  5. Make your own sid image in x64

    # variables
    $WORKPLACE=/space_change_me
    $BASEIMG=debian:buster
    $TAG=my/debian
    $RELEASE=sid
    $PLATFORM=arm
    
    # multiarch preparation
    apt-get update
    apt-get -y install apt-transport-https ca-certificates curl gnupg lsb-release
    curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
    echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
    apt-get update
    apt-get -y install qemu binfmt-support qemu-user-static docker-ce byobu make
    export DOCKER_CLI_EXPERIMENTAL=enabled
    
    #build image
    docker run  -i --rm -v $WORKPLACE:/data $BASEIMG /bin/bash  << EOF
    export DEBIAN_FRONTEND="noninteractive" 
    apt-get -y update
    apt-get -y install debootstrap
    debootstrap --verbose --include=iputils-ping --arch $PLATFORM $RELEASE /data/$RELEASE-$PLATFORM $REPO
    chroot /data/$RELEASE-$PLATFORM/ /bin/bash << SEOF 
    export DEBIAN_FRONTEND="noninteractive"
    apt-get -y update
    apt-get -y upgrade
    apt-get -y clean
    SEOF
    rm -R /data/$RELEASE-$PLATFORM/debootstrap
    EOF
    
    cd $WORKPLACE/$RELEASE-$PLATFORM
    tar cpf - . | docker import - $TAG:$RELEASE-$PLATFORM --platform $PLATFORM
    docker save $TAG:$RELEASE-$PLATFORM  > debian-$RELEASE-$PLATFORM.tar
    

    You can load later in the arm host with

    cat debian-$RELEASE-$PLATFORM.tar |docker load

  6. At least one invalid signature was encountered

    The error suggests that one of the files in /var/lib/apt/lists consist at least one invalid/corrupted signature (could be the result of apt-key misuse or something else).

    Try to run Apt update with the debug messages:

    apt-get -oDebug::pkgAcquire::Worker=1 update
    

    which should point you to the corrupted file, e.g.

    0% [Working] <- gpgv:400%20URI%20Failure%0aMessage:%20At%20least%20one%20invalid%20signature%20was%20encountered.%0aURI:%20gpgv:/var/lib/apt/lists/partial/CorruptedFile_InRelease

    Edit the file, find and remove the corrupted parts, or remove the whole file, so it can be recreated.

  7. None of these worked for me. This command did the trick though:

    docker volume prune
    

    Literally had 249GB worth of volumes that I was able to reclaim.

  8. @Jack Kawell got it right.

    docker builder prune
    

    This command does the trick.
    Beware of the command "docker system prune" as this would delete all your images (very destructive).
    The builder prune only deletes the build cache that is where your have all your previous (cached) builds steps.

  9. I tried a few of the above answers, and none of them worked for me. The real trigger was when I used --allow-unauthenticated and --allow-insecure-repositories from @Wytrzymały Wiktor‘s answer, and I got a notification showing

    tar: ./conffiles: Cannot utime: Operation not permitted
    tar: ./control: Cannot utime: Operation not permitted
    tar: ./md5sums: Cannot utime: Operation not permitted
    tar: ./postinst: Cannot utime: Operation not permitted
    tar: .: Cannot utime: Operation not permitted
    tar: Exiting with failure status due to previous errors
    

    This lead me down a route where I found this post which suggested that the issue may be where libseccomp2 was outdated.

    The fix there was to do:

    # Get signing keys to verify the new packages, otherwise they will not install
    sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 04EE7237B7D453EC 648ACFD622F3D138
    
    # Add the Buster backport repository to apt sources.list
    echo 'deb http://httpredir.debian.org/debian buster-backports main contrib non-free' | sudo tee -a /etc/apt/sources.list.d/debian-backports.list
    
    sudo apt update ; sudo apt install libseccomp2 -t buster-backports
    

    Note that this assumes that you’re using Raspbian and a version of docker after 19.04

  10. I had the same problem. It looks like it was lack of space. I’ve removed old images and it started to work.

    $ docker images

    Select the ones you don’t care anymore (to delete).

    $ docker rmi <image_id>

    The following command filter the dangling images and remove those.

    docker rmi $(docker images -q --filter "dangling=true")

  11. @BoyArmy_89 solves my similar problem; I tried all the other solutions but only the following worked:

    docker volume prune

  12. In my case I was trying to run a Docker debian:stable (bullseye at the moment) in a Raspberry PI with a buster distribution of the OS.

    Changed to debian:busterand it worked

    Hope this will help someone out there
