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 - /etc/php/7.4/cli/conf.d/10-opcache.ini - /etc/php/7.4/cli/conf.d/10-pdo.ini - /etc/php/7.4/cli/conf.d/20-bcmath.ini - /etc/php/7.4/cli/conf.d/20-calendar.ini - /etc/php/7.4/cli/conf.d/20-ctype.ini - /etc/php/7.4/cli/conf.d/20-exif.ini - /etc/php/7.4/cli/conf.d/20-ffi.ini - /etc/php/7.4/cli/conf.d/20-fileinfo.ini - /etc/php/7.4/cli/conf.d/20-ftp.ini - /etc/php/7.4/cli/conf.d/20-gettext.ini - /etc/php/7.4/cli/conf.d/20-iconv.ini - /etc/php/7.4/cli/conf.d/20-json.ini - /etc/php/7.4/cli/conf.d/20-mbstring.ini - /etc/php/7.4/cli/conf.d/20-mysqli.ini - /etc/php/7.4/cli/conf.d/20-pdo_mysql.ini - /etc/php/7.4/cli/conf.d/20-phar.ini - /etc/php/7.4/cli/conf.d/20-posix.ini - /etc/php/7.4/cli/conf.d/20-readline.ini - /etc/php/7.4/cli/conf.d/20-shmop.ini - /etc/php/7.4/cli/conf.d/20-sockets.ini - /etc/php/7.4/cli/conf.d/20-sysvmsg.ini - /etc/php/7.4/cli/conf.d/20-sysvsem.ini - /etc/php/7.4/cli/conf.d/20-sysvshm.ini - /etc/php/7.4/cli/conf.d/20-tokenizer.ini - /etc/php/7.4/cli/conf.d/20-zip.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:

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
Answer:
As error says, You should explicitly select one to install.
Search for php version on your machine by
|
1 2 |
php --version |
then use that version to install the package
|
1 2 3 4 5 |
sudo apt-get install -y php # 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.
