Jedidja's questions

Almost all my data is stored on my Data Drive (/dev/sda1) I moved my Documents and Music folders and so on to this drive. Now I want to add it to the Nautilus (1:3.26.4-0) sidebar in Ubuntu 18.04.

It doesn't need to mount somewhere else. The custom paths to folders like Documents in the sidebar are working fine.

I just want a nice button to click on to take me directly to my data drive so I don't have to bother with going through Other Locations - Data anymore. Since it's not a folder I can't just drag and drop it to bookmark it.

For an assignment I have to write a function that prints the number of even numbers when provided with a sequence of numbers.

I used the piece of code I used for a previous assignment (to print 1 when a number was even and 0 when the number was odd)

My problem now is that my function keeps printing 0. What am I doing wrong?

Here's my script:

#!/usr/bin/bash
# File: nevens.sh

# Write a function called nevens which prints the number of even numbers when provided with a sequence of numbers.
# Check: input nevens 42 6 7 9 33 = output 2

function nevens {

        local sum=0

        for element in $@
        do
                let evencheck=$(( $# % 2 ))
                if [[ $evencheck -eq 0 ]]
                then
                        let sum=$sum+1
                fi
        done

        echo $sum
}

While updating my nvidia drivers I got a warning about inconsistent python 3 package and the advise to reinstall python 3.

Searching the forum gave me another post with the exact same warning (Python 3 not working) and a nice solution by David Foerster https://askubuntu.com/a/914589/672852.

However, after trying this:

sudo apt install -f --reinstall python3 python3.4 python3-minimal python3.4-minimal libpython3.4-minimal

I got the following notice:

Pakket libpython3.4-minimal is niet beschikbaar, hoewel er naar verwezen wordt door
een ander pakket. Mogelijk betekent dit dat het pakket ontbreekt,
verouderd is, of enkel beschikbaar is van een andere bron
E: Pakket 'libpython3.4-minimal' heeft geen kandidaat voor installatie

And for the non-Dutch speakers:

Package libpython3.4-minimal is not available [...]
E: Package 'libpython3.4-minimal does not have a candidate for installation.

The question being: how do I reinstall Python3 now?

Oh yes, this problem started after a fresh install of 16.04. And I did the fresh install due to problems with the 17.04 upgrade.
