[08:39] <apw> enyc, which packages have you installed for these old kernels
[09:09] <enyc> apw: just ubuntu kernels from 18.04 and possibly before, there were various series of hwe kernels over time
[09:10] <enyc> apw: i found out that the sata_sil module i'm using is actually in a -extras package
[09:10] <enyc> apw: which was why i couldn't boot, anyhow =)
[09:10] <apw> enyc, which makes sense indeed
[09:11] <apw> enyc, as the kernel is incomplete (as -generic) without -extras; that eseenstially is you installing -virtual ie a kernel which has what a VM needs not what metal needs
[09:12] <enyc> apw: i've just copied onto my 20.04/mint20 system the /boot/ files and /lib/modules  files from these older 2 kernels,  which is enough to rebuild initramfs and rebuild grub  so they will boot and 'work'
[09:12] <enyc> and run older dvb-t2 driver and try to figure out wtf going on!
[09:14] <apw> unauthadox and hard to clean up from afterwards, but each to their own
[09:46] <enyc> apw: easy to clean up, remove same files and update-grub, no problem
[09:46] <enyc> its' just ... package syse not away of thex tra old kernels
