and some other solutions, but didn't work.

Update 2:

A popup came from the system software updater and wanted to update. I updated and after that update, I have this issue

Update 3:

I didn't know which third-party app to remove, so I didn't remove any third-party apps.

If you really want to use the PPA

It seems that the package libpcre2-posix2 is trying to overwrite a library used by libpcre2-posix3.

Give apt the permission to overwrite the file.

sudo apt-get -o Dpkg::Options::="--force-overwrite" install libpcre2-posix2

Then, run sudo apt update, and sudo apt install -f and sudo apt upgrade.

If you don't want to use the PPA

The following command should remove the PPA and the conflicting packages.

sudo apt install ppa-purge
sudo ppa-purge ppa:ondrej/php
