PPA repositories are designed for Ubuntu systems, not Debian. Use Debian-specific ARM repositories or package sources instead.

Ok, I now see that this PPA is Ubuntu specific, even though the Ubuntu distribution is derived from Debian. Is there a PPA repository for 'kdiskmark' as you had advised?

Any PPA is not intended for Debian. Here you go: https://packages.debian.org/trixie/arm64/kdiskmark/download
