PHP 7 issue with mcrypt (TT-RSS & Owncloud don't work anymore)

After updating my system, the websites on my server tt-rss and owncloud don't work anymore. The command

php -m

gives me:

PHP Warning:  PHP Startup: mcrypt: Unable to initialize module

The Website tt-rss shows the message:

Startup failed
Tiny Tiny RSS was unable to start properly. This usually means a misconfiguration or an incomplete upgrade. Please fix errors indicated by the following messages:

FEED_CRYPT_KEY requires mcrypt functions which are not found.
You might want to check tt-rss wiki or the forums for more information. Please search the forums before creating new topic for your question.

Owncloud only says HTTP ERROR 500 after login in.

I once had the same issue, but I downgraded back to PHP5, because I had no time. But this is no solution anymore! Now I sit for hours in front of this issue and have no idea what the problem is? Can you help me please?

Let the tt-rss and owncloud devs know things break with php 7.2, check their bug trackers as most probably someone already reported the problem and maybe there are workarounds. In the mean time downgrade php to a version that is supported by the things you want to use.

Is there some kind of script which can downgrade all PHP packages to version 5.6, because I don't have those packages in my cache anymore

If someone knows a more comfortable way to downgrade without downloading every package by hand, please let us know.

If tt-rss and owncloud only work with php 5.6 then I suppose you'd have to build it again from the AUR, if they work with php 7.1 it _might_ be enough to downgrade using Arch Linux Archive[1]. There is always a chance that you might have to recompile php 7.1 yourself if it depends on some library that had a soname bump in the meantime.

I had issues with mcrypt too.

The package php-mcrypt was removed in PHP 7.2, and it seems [1] that it was replaced with php-sodium

It has been exhaustively confirmed that php 7.1 is linked to old versions of ICU, e.g. https://bugs.archlinux.org/task/56553#comment163996

Arch Linux
