**Your software**  
My PHP version is : 8.0.30  
My MariaDB version is mariadb Ver 15.1

**Updating/Installing Errors**  
I am installing via Command Line

_These errors are showing in the installer_ :

Problem 1  
- Root composer.json requires mautic/mautic-saelos-bundle ~2.0 → satisfiable by mautic/mautic-saelos-bundle[2.0, 2.1].  
- mautic/mautic-saelos-bundle[2.0, …, 2.1] require tightenco/collect ^5.6 → found tightenco/collect[v5.6.0, …, v5.8.38] but these were not loaded, likely because it conflicts with another require.

_These errors are showing in the Mautic log_ :

There is no [mautic\_root]/var/logs folder

_How do I fix the tightenco problem?_
