dpkg: error processing archive /var/cache/apt/archives/samba-libs_2%3a4.1.6+dfsg-1ubuntu2_amd64.deb (--unpack):

Solution

This is the clue,

secrets.tdb exists in /var/lib/samba and /var/lib/samba/private, aborting samba-libs preinst
rename one of them to allow the install/upgrade to continue

So moving the file /var/lib/samba/secrets.tdb to another location will solves your problem,

sudo mv /var/lib/samba/secrets.tdb ~/Desktop

And then run the below command to fix dependencies,

sudo apt-get install -f
