I can confirm that the timidity-daemon package in jammy-proposed has fixed the bug for me.
Test done: 1. Try installing timidity-daemon on a jammy installation and it failed to install. 2. Add jammy-proposed to apt sources 4. Upgrade timidity-daemon from jammy-proposed and it installed without any failure. 5. Check service status as a basic test $ systemctl status timidity.service ● timidity.service - LSB: start and stop timidity Loaded: loaded (/etc/init.d/timidity; generated) Active: active (exited) since Sun 2024-03-17 22:32:37 GMT; 5s ago Docs: man:systemd-sysv-generator(8) Process: 3346 ExecStart=/etc/init.d/timidity start (code=exited, status=0/SUCCESS) CPU: 56ms Mar 17 22:32:37 sudip-Standard-PC-i440FX-PIIX-1996 systemd[1]: Starting LSB: start and stop timidity...
