Guys, I noticed that my php version is still at 7.2 and cannot be updated to 7.4 automatically. Shouldn't be updated through apt easily? I searched in the forum but I only found instructions of installing multiple php version on Debian not ubuntu (I know they are similar, but can't risk it) Please advise how to proceed
No. The base PHP version belongs to the operating system and gets only raised when you upgrade to a new major version of the OS. So you'll get PHP 7.4 when you upgrade to Ubuntu 20.04. But an upgrade is not required as Ubuntu patches the version that ships with 18.04 for security issues and you can install newer and older PHP versions alongside PHP 7.2 and use that in the hosted websites.
So I should add add-apt-repository ppandrej/php and download PHP 7.4 from apt and then set multiple versions in ISPconfig panel? Also when I install PHP 7.4 with above way the older 7.2 version and conf files will still remain at place and all my webs are going to be working properly? (I am on a production server)
Follow this guide: https://www.howtoforge.com/tutorial...fig-3-from-debian-packages-on-debian-8-and-9/ The only difference for Ubuntu systems is that you add the ondrej ppa instead of the sury repository at the beginning. Both are from the same maintainer btw.
