Pihole stopped blocking

The issue I am facing:

Pi-hole has stopped blocking sites. It says that a site is blocked, but replies to queries with the IP addresses - as if it was not there.

Here's an example:

$ pihole -t

08:08:19: query[A] cnn.com from 90.250.186.18
08:08:19: forwarded cnn.com to 8.8.8.8
08:08:19: reply cnn.com is 151.101.1.67
08:08:19: reply cnn.com is 151.101.129.67
08:08:19: reply cnn.com is 151.101.193.67
08:08:19: reply cnn.com is 151.101.65.67
08:08:20: query[PTR] 202.249.54.154.in-addr.arpa from 178.62.18.240
08:08:20: cached 154.54.249.202 is crawl-prodd4-10.babbar.eu
08:08:22: query[A] profile.accounts.firefox.com from 90.250.186.18

$ pihole -b cnn.com
  [i] cnn.com already exists in blacklist, no need to add!
$ pihole -v
  Pi-hole version is v5.11.4 (Latest: v5.11.4)
  AdminLTE version is v5.13 (Latest: v5.13)
  FTL version is v5.0 (Latest: v5.16.1)
$ dig cnn.com

Please upload a debug log and post just the token URL that is generated after the log is uploaded by running the following command from the Pi-hole host terminal:

pihole -d

or do it through the Web interface:

Your FTL is also way outdated.

FTL version is v5.0 (Latest: v5.16.1)

Yes, thank you - I've been trying to fix that, by working around this:

[i] Processing apt-get install(s) for: lighttpd php7.4-cgi php7.4-sqlite3, please wait...
E: Unable to correct problems, you have held broken packages.

I'm having trouble installing the correct versions on linux - it seems to want earlier versions than the versions that I have installed:

The following packages have unmet dependencies:
 php7.4-cgi : Depends: php7.4-common (= 7.4.3-4ubuntu2.12) but 7.4.9-1ubuntu1.2 is to be installed
 php7.4-sqlite3 : Depends: php7.4-common (= 7.4.3-4ubuntu2.12) but 7.4.9-1ubuntu1.2 is to be installed

You need to resolve the OS level package issues before Pi-hole will update to completion. Two quick search engine links:

Do we know when a new version of pihole is coming out?

The problem I've been getting is that this version's FTL relies on an old version of php-7.4 (7.4.3 when the latest is 7.4.9)

I was able to get running again with:

systemctl start pihole-FTL

Soon .... We hope to ship still in August, but some bigger changes need proper testing.

However, this has nothing to do with

This is an OS level issue. Pi-hole works with all PHP > 5.6

I have finally fixed this - but by brute force:
