Installing php7 on alpine: missing libcrypto and libssl

I tried to setup a LEMP stack over Alpine GNU/Linux Distribution running on a VM **WITHOUT** docker. Then I tried to install the php7-mysqli over via community repositories with: sudo apk add php7-mysqli But I got the following errors: ERROR: unsatisfiable constraints: so:libcrypto.so.43 (missing): required by: php7-openssl-7.2.5-r0[so:libcrypto.so.43] php7-openssl-7.2.5-r0[so:libcrypto.so.43] so:libssl.so.45 (missing): required by: php7-openssl-7.2.5-r0[so:libssl.so.45] php7-openssl-7.2.5-r0[so:libssl.so.45] I have installed libressl but the errror still persists. Any idea why that happens? Keep in mind I have set to the repositories to the community's one: http://dl-2.alpinelinux.org/alpine/edge/community #Edit 1: I followed the instructions mentioned in https://www.cyberciti.biz/faq/how-to-install-php-7-fpm-on-alpine-linux/ #Edit 2: I tried to install libressl2.6-libcrypto-2.6.3-r0 via the following command: sudo apk add libressl2.6-libcrypto-2.6.3-r0 And I got the following output: ERROR: unsatisfiable constraints: libressl2.6-libcrypto-2.6.3-r0 (missing): required by: world[libressl2.6-libcrypto-2.6.3-r0] If I try to install the libressl package I get the following response: sudo apk add libressl (1/2) Installing libressl2.6-libtls (2.6.3-r0) (2/2) Installing libressl (2.6.3-r0) Executing busybox-1.27.2-r8.trigger OK: 119 MiB in 53 packages And the problem still remains. Also the I tried to install libressl2.7-libcrypto via: sudo apk add libressl2.7-libcrypto And I got the following errors: ERROR: unsatisfiable constraints: libressl2.7-libcrypto (missing): required by: world[libressl2.7-libcrypto]
