trouble installing SQLite

Question

using a Raspberry Pi 3B with Raspbian Jessie I get this error when installing sqlite3 with

sudo apt-get install sqlite3

Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
libc6 : Depends: libgcc1 but it is not going to be installed
sqlite3 : Depends: libreadline6 (>= 6.0) but it is not going to be installed
Depends: libsqlite3-0 (= 3.8.7.1-1+deb8u2) but it is not going to be installed
Depends: libtinfo5 but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

sudo apt-get -f install

Gives me this error:

Can anyone help me out please?

Edit update:

sudo apt --reinstall install debconf

gives me this error:

The following packages have unmet dependencies:
debconf : PreDepends: perl-base (>= 5.20.1-3~) but it is not going to be installed
Recommends: apt-utils (>= 0.5.1) but it is not going to be installed
Recommends: debconf-i18n but it is not going to be installed
libc6 : Depends: libgcc1 but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

sudo apt-get -f install

Keeps giving the same 'dependency' error as above

Answer 1

The error message is

E: Cannot get debconf version. Is debconf installed?

This is needed to configure installed packets. Check if it is available:

rpi3 ~$ debconf --help

Check if it is installed:

rpi3 ~$ sudo apt update
rpi3 ~$ sudo apt full-upgrade
rpi3 ~$ apt list debconf

If not installed:

rpi3 ~$ sudo apt install debconf

If installed, try to reinstall it:

rpi3 ~$ sudo apt --reinstall install debconf

Updating to stretch solved the problem!
