MarsSeed [1] filed a deletion request for ksysguard [2]: Broken and not useful to keep. Upstream's last release was 2.5 years ago [a], and it's been EOL for more than a year; repo is archived. [b]
The package fails to build on current Arch Linux due to being incompatible with the currently available libraries. Superseded by Plasma System Monitor, available in repo.
