Somethinghas gone seriously wrong: import_mok_state() failed : Not Found
On Acer ES1-512. When installed in Legacy mode it boot's and installs with 0 problems. But when I go to shut down or restart - nothing, stays on black screen till I press the power button.
Didn't have problems with eOS 5. It was working fine in UEFi mode.
Some other distros are acting the same way - KDE Neon and the latest Mint 19.3 are doing the same for me. But Xubuntu and Lubuntu - both 19.10 for example work perfectly fine in UEFI mode.
Please take a look and find a solution.
