Asked by Gerardo Martínez Cabruja

When starting, there is a list of services started with "ok" mark, but suddendly, it stops and last charged service is:
[OK] Started Gnome Display Manager....
and then we have this:
[57.279761] PK CS#7 singature not signed with a trusted key
[57.386965] PK CS#7 singature not signed with a trusted key
[57.398794] PK CS#7 singature not signed with a trusted key
[57.405869] PK CS#7 singature not signed with a trusted key

After this, nothing happens.

If you boot an older kernel is it OK?

I have not tryed; besides, I do not know how to do it.

All problems began when I cloned the HDD into a hybrid one. Before this, I never had starting problems.

Best Regards

Hold SHIFT at boot then use cursor keys and ENTER. Choose a kernel that isn't the newest and not the recovery console. Does that boot OK?

Hello:
First of all, apologize for late answer.
I tryed to start with kernel 3.13.092 generic: black screen with a short list of errors
With kernel 5.0.0.15 generic: charget "OK" list until "Started Accounts Service"..... after that, hothing happened
With kernel 5.0.0.19 generic (I suppose this is the actual one): The same errors as pictures I uploaded

The problem is still giving me headaches. I must try starting several times until I get the complete start of the system.

Thak you for your answer,

Best Regards
