Unresolved depency and scx.service exit code

Issues & Assistance
1

Hi, Thanks for your help.

I have this problem that linux-cachyos-rc-zfs dependency unresolved when I want to add linux-cachyos-rc

resolving dependencies...
warning: cannot resolve "linux-cachyos-rc=6.14.rc7-3", a dependency of "linux-cachyos-rc-zfs"
:: The following package cannot be upgraded due to unresolvable dependencies:
      linux-cachyos-rc-zfs

:: Do you want to skip the above package for this upgrade? [y/N]

then another thing. I usually keep rebooting my system until this status changed by it self. or is there a way to make it work

I’m really sorry I’m such a mess. Thank you so much for your OS and your help

Are you using ZFS? If so, you can’t use 6.15 right now because ZFS doesn’t build.

Please show the full log by checking journalctl -u scx.service. Usually the service fails to start if /etc/default/scx has invalid syntax or you’re already using scx_loader.

right now it’s working. after few reboots and finally it’s working.

here’s my journalctl

Apr 10 15:44:21 cachyos-desktop systemd[1]: Started Start scx_scheduler.
Apr 10 15:44:22 cachyos-desktop bash[1049]: 08:44:22 [INFO] scx_lavd scheduler is initialized (build ID: 1.0.11-gdc>
Apr 10 15:44:22 cachyos-desktop bash[1049]: 08:44:22 [INFO] scx_lavd scheduler starts running.

and here’s my /etc/default/scx

# List of scx_schedulers: scx_bpfland scx_central scx_flash scx_lavd scx_layered scx_nest scx_qmap scx_rlfifo scx_r>
SCX_SCHEDULER=scx_lavd

# Set custom flags for each scheduler, below is an example of how to use
SCX_FLAGS='--performance'

Thank you so much for your reply

What about the entries where it fails to start? Also, you don’t have to reboot to get this working. You can just run sudo systemctl restart scx

Thank you so much for your reply.

I will try it when it’s error again. If it works I will mark it as a solution.

It needs sometime to have a working status. I usually to ‘sudo systemctl status scx’ right away after logged in. I give sometime like a minute if it’s still an error then sudo systemctl restart scx mostly worked. Thank you
