Initially, upgrade failed in UI.

I found 4-month bug report on similar topic, but I'm not sure how it can be resolved: https://askubuntu.com/questions/1377997/the-package-system-is-broken-in-ubuntu-21-04-with-php-ppa

[Kamil (kamil2018)]

I would like to add that I need to have installed several PHP versions together since 7.2 till 8.1.

[Kamil (kamil2018)]

Not sure whether it is relevant, but due to recent incidents with breaking some software for IP addresses based Russia, I think I need to say that upgrade was performed from IP address in Russia.

Issue is duplicated at https://github.com/oerdnj/deb.sury.org/issues/1747

[Kamil (kamil2018)]

Response at sury.org did not contain enough instructions for resolving issue, but by reaction on bug I understood that it is not serious. So, I resolved issue locally by myself in the following way (however, without full understanding of consequences):

sudo dpkg --purge libpcre2-posix2
sudo apt --fix-broken install
sudo apt upgrade

(The instructions are provided for those who encountered the same bug but have not enough knowledge in Linus administration.)

This issue may be closed.
