I have recently installed the latest linux66-rt kernel. All working fine, except on my attempt to remove the old kernel (linux61) using “sudo mhwd-kernel -r linux61” I get the error:
“…breaks dependency “linux61” required by linux-lts-meta”
I do not see that “linux-lts-meta” as a package or a file anywhere, so it must be in some config files somewhere?
linux-lts-meta is a meta package, which will automatically pull in the next oldest still-supported LTS kernel if the one you were running earlier is EOL (“end-of-life”). You can remove it.
It’s usually best to stick to normal kernels, unless you need real-time scheduling for something specific like professional audio production. Most people don’t need it.
