Debian build from mrfixit2001

[schmidtbag]

I used this disk image since the one by ayufan wouldn't boot.  It works fine and after a couple days I got everything set up the way I want, only to realize this is stuck at the same kernel version.  Not only that, but but this appears to be running as armhf, instead of arm64.  I'm really hesitant to just install the latest linux-image package because in my experience with other ARM systems, overriding a fixed kernel like that usually results in bricking the whole install.

I'm not using a GUI, so if upgrading the kernel means breaking the GPU drivers, that's fine - I don't care.  Anyone know if I can safely upgrade the kernel, let alone convert my setup to arm64 (I realize doing that would involve replacing just about every single package; that's fine)?

i was able to update to the latest ayufan one with a workaround discussed here

on kernel 5.6 now, start from 0.9.16 arm64; update and upgrade using the procedures mentioned and it should get you there.

Funny - that solution seems pretty obvious.  I'd have likely done the same thing, if I didn't have the mrfixit disk image to try.  But I really don't want to start all over again reconfiguring everything.  At the very least, I'd like to use the disk image I currently have and just upgrade the kernel without bricking it.  If I'm stuck with armhf, that isn't such a big problem for me, because aside from some MySQL commands, I overall don't think I'll see any performance improvements.  In some cases, 64-bit is actually slower on ARM.
