Upgrade of Ubuntu 20 via standard UI tool has failed. Here are the problems displayed in terminal after attempt to fix installation.

I use several PHP versions since 7.2 till 8.1, and Russian IP address (not sure whether it is issue, but just letting you know).

Another person reported the same problem here yesterday: https://askubuntu.com/questions/1400033/libpcre2-dev-depends-libpcre2-posix3-10-39-3ubuntu20-04-1deb-sury-org1
Also, I found similar 4-month old bug report here: https://askubuntu.com/questions/1377997/the-package-system-is-broken-in-ubuntu-21-04-with-php-ppa

Further you may see output from my terminal:

I did not try to resolve issue by giving to apt permissions to overwrite packages (as offered by one of the links posted in issue), just because I'm not proficient in such things and I'm afraid to break the whole tree of dependencies in the system. The problem is confirmed in one more source; so, I suppose it should be resolved on the side of repository.

Initially, I posted bug report at https://bugs.launchpad.net/ubuntu/+source/pcre2/+bug/1966855 But I suppose, this issue tracker is better location for such bug.

This 10.39-3+ubuntu20.04.1+deb.sury.org+1 is outdated version.
