so I get the following error while installing Pterodactyl panel:
Problem 1
- Installation request for aws/aws-sdk-php ^3.156 -> satisfiable by aws/aws-sdk-php[3.156.0].
- aws/aws-sdk-php 3.156.0 requires ext-simplexml * -> the requested PHP extension simplexml is missing from your system.
To enable extensions, verify that they are enabled in your .ini files:
- /etc/php/7.4/cli/php.ini
- /etc/php/7.4/cli/conf.d/10-mysqlnd.ini

You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
but then when doing sudo apt-get install -y php-simplexml
it gives me this:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package php-simplexml is a virtual package provided by:
php7.4-xml 7.4.10-1+ubuntu20.04.1+deb.sury.org+1
php7.3-xml 7.3.22-1+ubuntu20.04.1+deb.sury.org+1
php7.2-xml 7.2.33-1+ubuntu20.04.1+deb.sury.org+1
php7.1-xml 7.1.33-17+ubuntu20.04.1+deb.sury.org+1
php7.0-xml 7.0.33-30+ubuntu20.04.1+deb.sury.org+1
php5.6-xml 5.6.40-30+ubuntu20.04.1+deb.sury.org+1
You should explicitly select one to install.
E: Package 'php-simplexml' has no installation candidate
what can I do?
I'm new to ubuntu and have no clue of what to do
As error says, You should explicitly select one to install.
Search for php version on your machine by
php --version
then use that version to install the package
sudo apt-get install -y php<version>-xml
# so if you get 7.4 then it would be
sudo apt-get install -y php7.4-xml
Thanks to @bassxzero for noticing php version.
