Mainline tool is always recommend in this forum, but I didn't it get to work on my machine with the same error when I tried to install later kernels.
What worked for me was tuxinvader kernel 6.12 (replace 6.11 in the command of the guide with 6.12), liquorix I haven't tried yet which will offer kernel 6.16.
If you need a newer kernel you can consider to install Zorin 18 beta or wait until Tuesday, 14th october, then Zorin 18 with kernel 6.14 will be released.
