Several PHP 7.x / 8.x extension packages do not include the actual shared libraries in Ubuntu 18.04

[Stefan Hanreich]

While trying to install the newest versions of the extensions contained in the ppa I get a broken PHP build because some extensions do not include the shared library. This is on Ubuntu 18.04

I looked into the provided package files for imagick where the PHP7.0-8.1 .deb for 18.04 files did not contain any .so files. This only seems to be the case for PHP7 packages on amd64 arch. I only checked some select few to confirm my suspicions.

here are some examples from https://launchpad.net/~ondrej/+archive/ubuntu/php/+packages?field.name_filter=imagick&field.status_filter=published&field.series_filter=:

php7.4-imagick_3.5.1-2+ubuntu18.04.1+deb.sury.org+1_amd64.deb (12.9 KiB)
php7.4-imagick_3.5.1-2+ubuntu18.04.1+deb.sury.org+1_arm64.deb (83.9 KiB)
php7.4-imagick_3.5.1-2+ubuntu18.04.1+deb.sury.org+1_armhf.deb (82.4 KiB)
php7.4-imagick_3.5.1-2+ubuntu18.04.1+deb.sury.org+1_i386.deb (96.9 KiB)
php7.4-imagick_3.5.1-2+ubuntu18.04.1+deb.sury.org+1_ppc64el.deb (89.2 KiB)

You can see already that the amd64 .deb file is far smaller than the others.
This is the case for all PHP version in 18.04.

I haven't checked for any other versions, but at least some other packages for 18.04 seem to be affected. As far as I can tell mcrypt as well as xdebug have this issue as well.

God damn it sorry, I wanted to submit this to the respective PPA ondrej/php - SORRY! It seems to have redirected me the wrong way after registering.

edit: Seems like this is still the right place? Can you confirm this for me? Any idea where else the ondrej/php bug tracker might be?

[Bryce Harrington (bryce)]

Hi Stefan, this is text from the PPA about reporting issues:

"""
You can get more information about the packages at https://deb.sury.org

IMPORTANT: The <foo>-backports is now required on older Ubuntu releases.

BUGS&FEATURES: This PPA now has a issue tracker:
https://deb.sury.org/#bug-reporting

CAVEATS:
1. If you are using php-gearman, you need to add ppa:ondrej/pkg-gearman
2. If you are using apache2, you are advised to add ppa:ondrej/apache2
3. If you are using nginx, you are advised to add ppa:ondrej/nginx-mainline
   or ppa:ondrej/nginx
"""

Hope this helps!
