Comment 5 for bug 1966855

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.
