adding RUN echo -e "http://nl.alpinelinux.org/alpine/v3.5/main\nhttp://nl.alpinelinux.org/alpine/v3.5/community" > /etc/apk/repositories fixed my issue

Had this issue, but realized that it was a defective docker bridge or something. Restarting the daemon fixed it for me and the troubleshooting process was working back from DNS resolution, routing, etc from the pertinent host.

It’s DNS issue you can solve it by using the following steps:

  1. Find your DNS ip using below command nmcli dev show | grep ‘IP4.DNS’

IP4.DNS[1]: 192.168.0.1 <your-dns-ip-maybe-different>

  1. Create a file in the desktop which name is deamon.json and file has below data: { “dns”: [“192.168.0.1”, “8.8.8.8”] }

note: replace that ip “192.168.0.1” to your dns ip

  1. Go that directory /etc/docker/ in your system and paste file deamon.json that you just created

  2. Then restart your docker/your system, it will solve your issue.

In my case installing the latest libseccomp on my host fixed it. I had to download it manually on my latest raspbian as the latest version is not yet in the apt repos. The accepted answer in this “askubuntu” thread helped me: https://askubuntu.com/questions/1263284/apt-update-throws-signature-error-in-ubuntu-20-04-container-on-arm

Packages for debian(-based): https://packages.debian.org/sid/libseccomp2

Just download the one that fits your architecture and install with dpkg (again: only debian based). Example for raspbian: wget http://ftp.de.debian.org/debian/pool/main/libs/libseccomp/libseccomp2_2.5.1-1_armhf.deb sudo dpkg -i libseccomp2_2.5.1-1_armhf.deb

alexandermuehle on Mar 19, 2018

as pointed out by @azyata its can be a problem with the DNS settings

If you are performing apk add inside the container, below might be helpful

From docs.docker.com:

By default, a container inherits the DNS settings of the Docker daemon including the /etc/hosts and /etc/resolv.conf

  1. Try to ping
ping dl-cdn.alpinelinux.org

if it doesn’t work

  1. Check DNS configuration in /etc/resolve.conf in host machine, try adding
nameserver 8.8.8.8

then perform ping

ping dl-cdn.alpinelinux.org

if it works for you, then

  1. Restart the docker daemon
sudo systemctl restart docker

^ This solved the problem for me.

In the above case, obtaining via CDN was resolved by using the ‘–network=host’ option at build time.

docker build -t sample --network=host .

I got the above “unsatisfiable constraints” IO ERROR WARNING but I was able to curl(download) them from the host.

So I assumed that CDN wasn’t down but something wrong about docker’s network. I set the network as host by --network=host option and started to download. Hope this helps.

Just posting here in case somebody else lands here trough google and all of the above did not fix their problem.

On my raspberry Pi with docker i ran into the same issue yesterday: RUN apk add --no-cache acl fcgi file gettext git;

Results in:

My search eventually landed me on:

docker-library/php#1118

From which i took away two things:

  • The cause seems to be a ipv6 issue
  • Alpine v3.12 does not seem to have the issue

Downgrading from alpine3.13 to alpine3.12 solved it for me.

Rme2001 on Mar 23, 2021

Had the same error trying to build an alpine-sdk docker using Docker Windows 10. Checked the status of the server, and the server was fine and reachable outside docker.

Restarting docker did the trick for me. Looking in the Docker log file it’s clear that the DNS configuration was set incorrectly. So when seeing this error in a docker context, try to restart docker first.

I tried most of the previous tips; however, only this one work for me.

  1. Check available networks

docker network ls

output … a81de1c029c9 host host local

  1. Building image with --network=host

docker image build … --network=host .

If you do not know what the reason is, then it is probably DNS

  • 8.8.8.8 cannot resolve dl-cdn.alpinelinux.org
  • ns1.alpinelinux.org can resolve dl-cdn.alpinelinux.org
  • dl-cdn.alpinelinux.org is CNAME for global.prod.fastly.net

WGrape on Oct 17, 2023

Dirty hack for resolving this without changing daemon settings:

RUN \
    # DNS problem workaround
    # https://github.com/gliderlabs/docker-alpine/issues/386
    printf "nameserver 8.8.8.8\nnameserver 9.9.9.9\nnameserver 1.1.1.1" > /etc/resolv.conf \
    \
    && apk add --no-cache bash

Notice that it only affect current layer, in other layers you should add this patch too if needed.

Also you can pass custom DNS server from the ARGs.

I solved it by creating a daemon.json file in /etc/docker/

sudo nano /etc/docker/daemon.json

and inserting:

{
  "bip": "192.168.1.5/24"
}

Restart docker and try again:

sudo systemctl daemon-reload
sudo systemctl restart docker

If I were to guess I’d say that docker bridge0 clash with the proxy in some way?

I believe this happens when MTU in the container differs from the MTU on the host. What happens is that Fastly filters out need-to-frag ICMP packets so Path MTU is broken on fastly (and dl-cdn.alpinelinux.org).

update my server DNS to Google DNS 8.8.8.8 8.8.4.4 solve this for me

Had the same problem with php 7.4 alpine image in Ubuntu inside Windows (WSL2). I was trying to install the imagick extension via pecl and kept getting “No releases available for package pecl.php.net/imagick” error. Changing the nameserver to google’s 8.8.8.8 solved it for me. Thank you.

$ sudo vi /etc/resolv.conf # change nameserver to 8.8.8.8

I had disabled firewalld with no joy. I restarted docker and the issue was fixed.

This is wild. Repos constantly just break and anytime you have a new vm you need to troubleshoot all of this over again?

I’m behind a proxy and I experienced a similar error:

fetch http://dl-cdn.alpinelinux.org/alpine/v3.10/main/x86_64/APKINDEX.tar.gz
ERROR: http://dl-cdn.alpinelinux.org/alpine/v3.10/main: temporary error (try again later)
WARNING: Ignoring APKINDEX.00740ba1.tar.gz: No such file or directory
fetch http://dl-cdn.alpinelinux.org/alpine/v3.10/community/x86_64/APKINDEX.tar.gz
ERROR: http://dl-cdn.alpinelinux.org/alpine/v3.10/community: temporary error (try again later)
WARNING: Ignoring APKINDEX.d8b2a6f4.tar.gz: No such file or directory
2 errors; 15 distinct packages available

I solved it by creating a daemon.json file in /etc/docker/

sudo nano /etc/docker/daemon.json

and inserting:

{
  "bip": "192.168.1.5/24"
}

Restart docker and try again:

sudo systemctl daemon-reload
sudo systemctl restart docker

If I were to guess I’d say that docker bridge0 clash with the proxy in some way?

Solved with this solution. Thanks!!!

I had the same issue. I solved by putting proxy inside docker cointainer.

docker exec -it reports sh export http_proxy=http://ipaddress:port/ export https_proxy=http://ipaddress:port/ apk add --update ttf-dejavu

It downloaded required library with 200 OK exit status

Please use docker run -e OR docker build --build-arg to pass http_proxy env variable required for apk package manager

Seems your docker can not go out of host machine. Maybe this can help:

iptables -t nat -A POSTROUTING ! -o docker0 -s 172.17.0.0/16 -j MASQUERADE
