Some time ago I installed Ubuntu 16.04 on my PC. Everything went well and no problems so far. When the first kernel update came out I could not start it and got the following error:
Lvmetad is not active yet, using direct activation during sysinit Volume group "ubuntu-vg" not found Cannot process volume group ubuntu-vg
When I pick the old kernel from the GRUB menu it was ok and no problems there. After that another kernel update came out and also that one did not work out. Basically after clicking the newer kernel version I got the error and was repeated on the screen over and over again (with no end, not tested at least).
I tried the following without any luck:
lvmetad is not active yet; using direct activation during sysinit (tried the only answer to that one)
Neither worked. I have my disk encrypted as it was an option during the install and I thought why not? I think something is going on with that although it is more like a gut feeling than hard evidence. I searched if it is possible to deactivate the encryption and was a pretty tedious work, so I kind of stopped looking for that, but if that seems to be the solution I can still try it.
So the installed kernel version was
4.4.0-21-generic (as displayed in GRUB). Works fine no problems. After that the installed kernels were
4.4.0-28-generic (as seen in GRUB). Which all three don't work and give the exact same previous error.
Why am I getting the error and how do I solve it?
