Kernel installation seems fine. All modules (bbswitch and nvidia) are at kernel’s tree in the proper places. The only point to mention is that it return the messages like this:
/usr/sbin/dkms: line 1418: /var/lib/dkms/bbswitch/0.8-6///module/symvers.gz: file or directory not found
About cups the following messages came up upon installation:
12/11 cups-filters Job for cups.socket failed. See "systemctl status cups.socket" and "journalctl -xe" for details.
Systemctl is below and journalctl -xe is attached:journalctl.txt (162,9 KB)

Hope everything is OK.
