Ubuntu Duplicate sources.list entry error on sudo apt-get install scala

I'm trying to install scala and keep running into this error when I type:

sudo apt-get install scala

I've got the following errors:

W: Duplicate sources.list entry http://dl.google.com/linux/chrome/deb/ stable/main amd64 Packages (/var/lib/apt/lists/dl.google.com_linux_chrome_deb_dists_stable_main_binary-amd64_Packages)
W: Duplicate sources.list entry http://dl.google.com/linux/chrome/deb/ stable/main i386 Packages (/var/lib/apt/lists/dl.google.com_linux_chrome_deb_dists_stable_main_binary-i386_Packages)
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/toolbelt.heroku.com_ubuntu_._en
E: The package lists or status file could not be parsed or opened.

I followed these instructions on how to fix it but it didn't work.

Here is my sources.list file

Since it is easy to run python in ubuntu. You can use the following python3 script to make a copy of the file with no duplicates. After which you can replace the older "sources.list" with the new file



l = set()
# remove duplicates by adding all the lines to a set
with open("/etc/apt/sources.list") as f:
    for line in f:
        l.add(line)
# write the new lines to a file in your home folder
with open("/home/brianbrix/sources.list", "w") as f:
    for line in l:
        f.write(line)
        f.write("\n")

# after that you can replace the sources file wwith the new one which has no duplicates

This solution worked with me.

First remove the duplicate source sudo rm /etc/apt/sources.list.d/google.list then sudo apt update and sudo apt upgrade

start a terminal and type:

gksu gedit

then type

open /etc/apt/sources.list.d/

and then look for the appropriate entry that's said to be a duplicate.

Check if they are the same and if that's the case enter a # in front of the duplicate entry.

Then save the file an in another terminal enter sudo apt-get update to check if the error has gone.
