Hi friends!
I'm new in this forum.
My issue is the next:
I have a laptop Samsung np300e4c with Ubuntu 20.04lts and i installed qiime2 and rstudio (for my job), then when I turn on the PC, it showed me the following:
Couldn't parse dbx signatures: -74
So, in order to fix the problem, I restarted by default BIOS settings, but now y turn on the PC and only shows the screen with Samsung icon and it does not charge the operative system.
Does anyone know how to fix it?
