So I have efi-secure-boot installed and while installing vbox during reboot I forgot to switch to enter-key. so afterward I got the same errormessage as here
i first followed the instruction on the linked page, but after this didnt work I followed the basic instruction here
finally because I got a locked-process message when sudo /sbin/vboxconfig
I used sudo fuser -v /var/cache/debconf/config.dat and killed the corresponding process, which let me set up a new efi-secure-boot key. after reebooting and entering the key, everything works fine for virtualbox.
however, I am not sure, if I created some security holes, while trying. egs. in the /root I have now two folders with the following content
root@username-home:~# ls -lR.:total 8drwxr-xr-x 2 root root 4096 Feb 16 09:06 module-signingdrwxr-xr-x 2 root root 4096 Feb 16 09:04 signed-modules./module-signing:total 12-rw-r--r-- 1 root root 783 Feb 16 09:06 MOK.der-rw------- 1 root root 1704 Feb 16 09:06 MOK.priv-rwx------ 1 root root 301 Feb 16 09:01 sign-virtual-box./signed-modules:total 8-rw-r--r-- 1 root root 785 Feb 16 09:06 MOK.der-rw------- 1 root root 1704 Feb 16 09:06 MOK.privat least some things are superflous no?
should I do some other checks, to see if I didnt open up any doors?
