My problem is that I wanted to install OwnCloud on ubuntu, and long story short, I had to downgrade PHP from v8 to v7.2 and I found problems
Honestly, I don’t really know the problem exactly but when I run the upgrade command, for example, I get this error
You might want to run 'apt --fix-broken install' to correct these. The following packages have unmet dependencies: libpcre2-dev : Depends: libpcre2-posix2 (= 10.39-2+ubuntu21.10.1+deb.sury.org+1) but it is not installed E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
Even when I run the apt –fix-broken install command, I get this message:
Reading package lists... Done Building dependency tree... Done Reading state information... Done Correcting dependencies... Done The following package was automatically installed and is no longer required: libpcre2-posix3 Use 'sudo apt autoremove' to remove it.

I want to solve this problem but most importantly, I want to learn more about Linux so any explanation is more than welcome. Thank you!
