Ubuntu 14.04 update to PHP7.4 was unsuccessful. Apt repo in ./sources.list.d/php.list updated their TLS cypher suite and it no longer supports those cypher suite that gnutls in ubuntu 14.04 supports (concretelly gnutls-cli (GnuTLS) 2.12.23 version). Possible solutions would be:
- try to update gnutls
- try to install PHP7.4 w/o apt
Since I was planning to update my WP server to finally use docker and move it to some modern hosting provider (Linode and Digital Ocean are the primary considerations currently) I decided to not fix this issue and just move along with the upgrade. What fallows are some of the outputs I received that helped me understand what is going on.
