Package: php-redis Version: 2.2.7-394-g892f928+2.2.7-3 After upgrading to the mentioned version of the package, I see the following warning when running PHP.
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/redis.so' - /usr/lib/php/20151012/redis.so: undefined symbol: igbinary_serialize in Unknown on line 0 I see that the package has a Recommends for php-igbinary, but since it seems to not function unless that package is installed you should either upgrade that to a Depends or revert the change that makes it required.
