Given the recent announcement that php 7.3 will be the lowest supported version as of Nov 2020, I tried to update my ubuntu 18 development server from 7.2 to either 7.3 or 7.4. I tried both, and am having issues with php-memcached.
It seems the preferred way to update U18 to 7.3 or above is to use packages from the ppa:ondrej/php repo. After updating to either 7.3 or 7.4 and reinstalling all required packages for the new version, I am receiving this error any time I run validate.php, daily.php, or any other PHP code:
PHP Warning: PHP Startup: Unable to load dynamic library 'memcached.so' (tried: /usr/lib/php/20180731/memcached.so (/usr/lib/php/20180731/memcached.so: undefined symbol: igbinary_serialize), /usr/lib/php/20180731/memcached.so.so (/usr/lib/php/20180731/memcached.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0
Any one else facing the same issues?
