PHP Startup: Unable to load dynamic library

[Maxmurgian]

Hi,

 

I recently updated from Ubuntu 14 to Ubuntu 16 and ran into trouble with my PHP installation. On U14 the installed version of PHP was php5. Updating to U16 kicked that out and installed php7.0 instead, which is fine as I wanted to move on to that anyway.

 

However, now, when I run PHP, I get the following warning:

 

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/curl.so' - libssl.so.1.0.2: cannot open shared object file: No such file or directory in Unknown on line 0

 

I have tried to remove and re-install php7.0 and everything that depends on it, but to no avail. Any help solving this would be very much appreciated, I really need to have this issue solved.

Do you have the cURL extension installed? There should be a package called something like "php-curl". Is the path "/usr/lib/php/20151012/" correct? Is that where your PHP 7 extensions reside?

Hi Jacques1,

 

Thank you for answering. Yes, I have the cURL extension installed, see below.

 

x@y:~$ php

^C

x@y:~$ la /usr/lib/php/20151012/

Although 'libssl.so.1.0.2' is nowhere to be found. Should it also reside here?

libssl is a system library from OpenSSL. Do a system-wide search for “libssl.so*” to check if there's any version present. If it isn't, install the libssl package.

It turned out that the version that came with the upgrade to Xenial was libssl1.0.0, but I managed to install libssl1.0.2:amd64 (1.0.2h-1+deb.sury.org~xenial+1) from PPA http://ppa.launchpad.net/ondrej/nginx/ubuntu xenial main

 

That did the trick, thanks!
