Hey everyone, I'm having a problem I'm hoping someone can help with. After my last update, there was an error updating. See screenshot.

I don't know how to fix this. I checked installed kernels and there were 9 current and 8 lts. So I removed all but 2 current and 1 lts, but clr-boot-manager update still fails with a "no space left on device" error.
Any ideas?
Much appreciated!
