I had a kernel update and its essentially broken my machine.
I managed after several times to get it to boot up by selecting an older kernel, but now I can't fix the kernels that are installed.
When I run sudo update-initramfs -k all -u -v
it hangs on:
Adding module /lib/modules/5.3.0-51-generic/kernel/drivers/md/raid10.ko
and then doesn't get any further. I'm not even sure which kernels work or not work, making me a bit worried about switching off my machine.
I am running Ubuntu 18.04 alongside a Windows 10 partition.
