答案1
如果你真的想使用 PPA
看起来该包libpcre2-posix2正在尝试覆盖所使用的库libpcre2-posix3。
授予apt覆盖文件的权限。
sudo apt-get -o Dpkg::Options::="--force-overwrite" install libpcre2-posix2
然后，运行sudo apt update，和sudo apt install -f和sudo apt upgrade。
如果你不想使用 PPA
以下命令应该删除 PPA 和冲突的包。
sudo apt install ppa-purge
sudo ppa-purge ppa:ondrej/php
