Encountering issue when updating to beta.7

UaMV

I'm encounter the following error when attempting my update to beta 7. Some issue with a php extension loading. Can anyone please advise on how to troubleshoot or fix this? Thanks!

UaMV where are you hosted? If you manage this machine yourself fix php, otherwise have your host fix it because they/you broke it during an upgrade.

The reason those PHP related messages are appearing is because you are trying to load those extensions, but they are not installed.

What version of PHP are you using? Can you post your active extensions?

I'm sure you know your way around your php config file, but sometimes when you don't comment out the extension correctly, it will fail to load it.

luceos Yeah, management of this machine unfortunately falls to me. ? The issue was related to a recent PHP update in mid-July. A quick search shows others are encountering a similar issue. I fixed things by reinstalling packages using the following command:

sudo apt-get install --reinstall `dpkg -l | grep 'ii  php7' | awk '{ printf($2" "); next}'`

Now running beta7! ?

This worked for me. In ubuntu 14.04 or above

sudo apt-get install libapache2-mod-php7.0 libphp7.0-embed libssl-dev openssl php7.0-cgi php7.0-cli php7.0-common php7.0-dev php7.0-fpm php7.0-phpdbg
