The issue you are facing:
Upgraded Ubuntu from 17.04 to 18.04, but for some reason nextcloud no longer starts. I usedthis guide to install nextcloud a couple months ago. I tried reinstalling php7 but get an error that

$ sudo apt-get install php7.0-curl
php7.0-curl is not available

nextcloud.mydomain.com gives the error:

Internal Server Error

The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.

mydomain.com works just fine.

Is this the first time you’ve seen this error? (Y):

Steps to replicate it:

  1. Upgrade Ubuntu from 17.04 to 17.10
  2. Upgrade Ubuntu from 17.10 to 18.04
  3. Try to access nextcloud

Update: Installed php7.2-curl php7.2-gd php7.2-xml php7.2-zip php7.2-mysql, this did not fix the issue.

Wow, that worked thanks! Turns out Ubuntu 18.04 updated some parts of php to 7.2 but left others at 7.0. When I tried to disable 7.2 it said it didn’t exist. So I disabled php7.0, and then:

sudo apt-get install php7.2-fpm php7.2-mysql php7.2-common php7.2-gd php7.2-json php7.2-cli php7.2-curl libapache2-mod-php7.2
sudo apt install php7.2-common php7.2-gd php7.2-json php7.2-curl  php7.2-zip php7.2-xml php7.2-mbstring
sudo a2enmod php7.2
sudo systemctl restart apache2

And now everything seems to be in order. Thanks a lot man!

This also worked for me, I’m assuming the exact same problem. Thanks very much!
