Unable to Install PHP Soap Extension on my Digital Ocean Droplet

I’m running a WordPress site and one of the plugins I’m using needs me to enable the PHP Soap Extension. However, I’m not able to enable it. I entered the command: sudo apt-get install php-soap after that I wrote “yes” for beginning the installation.

After writing “yes”, I got the list of errors which are mentioned below, from what I understand, it’s probably because of the mirrors not having the file. Is there something I’ve messed up with?

My website is Arabic Keyboard. It’s a tool which allows people to type in Arabic from the web and we’re working on something which would make the tool even better. Do you guys think I should shift to a different host? Sorry for the noob like questions, I’m not a power Linux terminal user.

I tried getting in touch with the support, but it doesn’t seem to be helpful, it’s almost 24 hours.
