I used a Dell laptop (model: Latitude 5511) with TPM 2.0 and secure boot enabled.
I tried to install UC-20 on this laptop but the installation process hung and without response finally.
The tested image: http://cdimage.ubuntu.com/ubuntu-core/20/beta/20201117.3/ubuntu-core-20-amd64.img.xz
The last screen is captured as 2 pictures and are attached here.
The key messages are:
picture#1:(uc20-fail-1.jpg)
"gadget does not support encrypted data: volume "pc" has no structure with system-save role"
picture#1:(uc20-fail-2.jpg)
"error: cannot set device information: No option model in section"
Besides, I did some testings on the same Dell laptop and the results are for references:
(1) Both TPM 2.0 and secure boot were NOT enabled
Both UC-18 and UC-20 can be installed
(2) Both TPM 2.0 and secure boot were enabled
UC-18 can be installed. |
