You are actually running v5.18.2:

*** [ DIAGNOSING ]: Core version
[✓] Version: v5.18.2
[i] Remotes: origin	https://github.com/pi-hole/pi-hole.git (fetch)
             origin	https://github.com/pi-hole/pi-hole.git (push)
[i] Branch: master
[i] Commit: v5.18.2-0-g5490a6ea

But your versions file has old information, causing the misleading message:
Pi-hole version is v5.17.2 (Latest: v5.18.2).

Try to run this command to update the file:

pihole updatechecker

Then try check the versions again with:

pihole -v

Thank you for letting me know I'm running the latest version.
I ran the updatechecker and have the same results:
carl@pihole:~ $ sudo pihole updatechecker
carl@pihole:~ $ sudo pihole -v
Pi-hole version is v5.17.2 (Latest: v5.18.2)
web version is v5.21 (Latest: v5.21)
FTL version is v5.25.1 (Latest: v5.25.1)

I have the same issue. It won't update tried resetting too but seems the update checker file is not updating correctly after 5.17.2.

cd /etc/pihole
sudo mv versions versions.bak
pihole updatechecker

This fixed it for me.
