I am trying to update my yii2 project with the composer but whenever I am giving an update command it is showing the following errors.



our requirements could not be resolved to an installable set of packages.



- phpunit/phpunit 5.6.2 requires ext-dom * -> the requested PHP extension dom is missing from your system.



 To enable extensions, verify that they are enabled in your .ini files:
 - /etc/php/7.2/cli/php.ini
 - /etc/php/7.2/cli/conf.d/10-opcache.ini
 - /etc/php/7.2/cli/conf.d/10-pdo.ini
 - /etc/php/7.2/cli/conf.d/15-xml.ini
 - /etc/php/7.2/cli/conf.d/20-calendar.ini
 - /etc/php/7.2/cli/conf.d/20-ctype.ini
 - /etc/php/7.2/cli/conf.d/20-curl.ini
 - /etc/php/7.2/cli/conf.d/20-dom.ini
 - /etc/php/7.2/cli/conf.d/20-exif.ini

 - /etc/php/7.2/cli/conf.d/20-iconv.ini
 - /etc/php/7.2/cli/conf.d/20-json.ini
 - /etc/php/7.2/cli/conf.d/20-mbstring.ini
 - /etc/php/7.2/cli/conf.d/20-phar.ini
 - /etc/php/7.2/cli/conf.d/20-posix.ini
 - /etc/php/7.2/cli/conf.d/20-readline.ini
 - /etc/php/7.2/cli/conf.d/20-shmop.ini
 - /etc/php/7.2/cli/conf.d/20-simplexml.ini
 - /etc/php/7.2/cli/conf.d/20-sockets.ini
 - /etc/php/7.2/cli/conf.d/20-sysvmsg.ini
 - /etc/php/7.2/cli/conf.d/20-sysvsem.ini
 - /etc/php/7.2/cli/conf.d/20-sysvshm.ini

 You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

          How to enroll fingerprints to Ubuntu 17.10 with VFS491

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 1 down vote favorite I decided to switch from Windows to Ubuntu 17.10, I meet it like 8 years ago and I didn't decided to switch until now (haha). Well, my actual device is an HP Probook 4540s with a Validity fingerprint sensor (VFS491). The fingerprint sensor worked fine on Windows but I can't get it to work in Ubuntu. The device is recognized as 138a:003d but is not detected as a fingerprint scanner by some apps like Fingerprint GUI. I want to use the fingerprint scanner to log in into my user account in Ubuntu but it doesn't supports fingerprints without special software and the drivers of the fingerprint scanner are available for Windows but not for any Linux distribution. I found something on GitHub (https://github.com/eekpie/libfprint) about the integration of the VFS491 in libfprint and I think it can help but I don't know what to do with it, so that's why I need the help of the community to do it since I am...
