php:5.6-apache Package has no installation candidate

[yudao]

Hi!

I have a Dockerfile with no problems until these last days:

FROM php:5.6-apache

ARG ENVIRONMENT=production

COPY lib/ /var/www/lib/

COPY htdocs/ /var/www/html/

COPY config/php.ini /usr/local/etc/php/

COPY config/000-default-${ENVIRONMENT}.conf /etc/apache2/sites-available/000-default.conf

RUN docker-php-ext-install mysql \
    && docker-php-ext-install opcache

RUN a2enmod rewrite \
    && a2enmod ldap \
    && a2enmod authnz_ldap

RUN apt-get update \
    && apt-get install -y ftp php5-ssh2 file imagemagick unzip libssh2-1 libssh2-1-dev php-pclzip zlib1g-dev \
    && pecl install ssh2 \
    && docker-php-ext-install zip \
    && docker-php-ext-enable ssh2

Now I have Package has no installation candidate errors:

Package php-pclzip is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

Package php5-ssh2 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'php5-ssh2' has no installation candidate
E: Package 'php-pclzip' has no installation candidate
remote: The command '/bin/sh -c apt-get update     && apt-get install -y ftp php5-ssh2 file imagemagick unzip libssh2-1 libssh2-1-dev php-pclzip zlib1g-dev     && pecl install ssh2     && docker-php-ext-install zip     && docker-php-ext-enable ssh2' returned a non-zero code: 100

Something has changed? Do I need to change something?

Thanks.

Yu.

Yep, see #542 -- the php-pclzip and php5-ssh2 packages you're trying to install will pull in Debian's PHP package, which will simply result in your image containing two separate copies of PHP, and those modules will not be enabled/included in the PHP from this image.

As far as I can tell, you'll need to install PclZip from http://www.phpconcept.net/pclzip/ and ssh2 via pecl.

... oh, which you're already doing. You probably just need to remove those two packages from your apt-get install line.

Thx @tianon working like a charm!
