No releases available for package "pecl.php.net/imagick". OpenSSL Error?

I apologise if this is a duplicate, but none of the already posted question's answers helped me.

Recently, the Dockerfile for our php5.6-apache doesn't want to build anymore. The line where it fails is when imagick is trying to be installed via pecl.

# Enable imagick
RUN apt-get update && apt-get install -y libmagickwand-dev --no-install-recommends && rm -rf /var/lib/apt/lists/*
RUN yes '' | pecl install -vvv imagick-beta

Running this line fails due to the following error:

 > [12/25] RUN yes '' | pecl -vvv install imagick-beta:

The only recent post I found about someone having the same issue is this bug report but I'm not sure about the channel where I'd see any updates on fixing this bug. In the bug report the last person states the following:

> Certificate expiry is set to yesterday. I'm thinking about all docker build pipelines currently failing all over the world <3

Does he mean about php.net's SSL certificate? Because when I checked it it looks valid so I don't understand why it can not connect.

line 183 of PEAR/proxy.php is the following:

$fp = @fsockopen($host, $port, $errno, $errstr);

So if I understand correctly, the docker container can not establish a proper connection via pecl.php.net:443? Has anyone encountered the same issue?

Thanks in advance for any (constructive) answers!

This is the fix that finally got everything working:

FROM php:alpine AS cacert

FROM php:7.0-fpm-alpine # Image that the container is actually using

COPY --from=cacert /etc/ssl /root/ssl

RUN mv /etc/ssl/openssl.cnf* /root/ssl && rm -rf /etc/ssl && mv /root/ssl /etc/ssl \
  && pear update-channels \
  && pear upgrade

From what I understand the CA cert is expired in older versions of PHP images and need to be replaced with a newer one. This might be a bit of hack but it will get you through until the older images' CA certs will be updated.

As I see it indicates that the SSL certificate verification failed, to fix it you can try disabling SSL certificate verification in the Dockerfile by adding this line before the pecl install command!

RUN pecl config-set "disable-tls" "yes"

or you can also updating the SSL certificate for pecl.php.net

good luck!

I was able to get around this problem by installing the packages directly from the project's git repository.

FROM php:7.0-alpine

RUN apk update && apk add --no-cache imagemagick-dev libtool make g++

RUN wget https://github.com/ImageMagick/ImageMagick6/archive/refs/tags/6.9.12-28.tar.gz && \
     tar -xzf 6.9.12-28.tar.gz && \
     cd ImageMagick6-6.9.12-28 && \
     ./configure && \
     make && \
     make install

RUN wget https://pecl.php.net/get/imagick-3.4.4.tgz && \
     tar -xzf imagick-3.4.4.tgz && \
     cd imagick-3.4.4 && \
     phpize && \
     ./configure --with-imagick=/usr/local && \
     make && \
     make install

RUN echo "extension=imagick.so" > /usr/local/etc/php/conf.d/imagick.ini
