Parsing XML not available

Hello everyone!
I have a problem that I can’t solve:
-SuiteCRM V. 7.11.18
-php 8.0.8
-Ubuntu 20

I’m trying to upgrade to the next version of Suite but I can’t because in the pre-upgrade checks I have an error:
XML Parsing Not available.
I tried to search the net without success, can someone help me?

thank you!

Hi,
Suite 7.11 does not support php8, so you need to downgrade. The missing xml support can be installed using e.g. sudo apt-get install -y php-xml.

perfect, with the downgrade it worked! Thanks so much
