[SOLVED] Cant run sudo apt-get update command

[Mathews]

I tried running the sudo apt-get update command from the terminal and I get this error 'E: Malformed entry 1 in list file /etc/apt/sources.list.d/additional-repositories.list (Component)
E: The list of sources could not be read.'
Anybody with the solution please help.

E: Malformed entry 1 in list file /etc/apt/sources.list.d/additional-repositories.list (Component)
E: The list of sources could not be read.

Hi Mathews,
Could you runcat /etc/apt/sources.list.d/additional-repositories.listin a terminal and post the output?

Just open 'Software Scources'/PPAs and temporarily deselect all the added PPAs
Then do your updates:
apt update
After your Mint updates you can reselect the PPAs one by one to find the offender.

This is the output

Code: Select all

cat /etc/apt/sources.list.d/additional-repositories.list
deb https://dl.winehq.orq/wine-builds/ubuntu/xenial main
deb https://dl.winehq.org/wine-builds/ubuntu/xenialmain
deb https://dl.winehq.org/wine-builds/ubuntu/xenial main

I had tried to download wine from the terminal earlier probably that's why it looks like that...

I don’t really have any added PPAs

[Sir Charles]

deb https://dl.winehq.orq/wine-builds/ubuntu/xenial main
deb https://dl.winehq.org/wine-builds/ubuntu/xenialmain
deb https://dl.winehq.org/wine-builds/ubuntu/xenial main

Alright, run:

Code: Select all

gksudo xed /etc/apt/sources.list.d/additional-repositories.list

When the file opens, delete the 2nd and the 3rd row. Save and close the file.
Next run:

Code: Select all

sudo apt-get update

Are you sure? Because that Wine PPA sure looks like an added PPA to me.

There seems to be a "subtle" difference between a "PPA" and an "Additional repository". A "PPA" is hosted by Launchpad, the software collaboration platform created by Canonical. On the other hand, any software developer can host his/her/its own repository providing .deb packages to be installed by the users. Like Oracle providing Virtualbox.

When you add a PPA to your system, likesudo add-apt-repository ppa:libreoffice/ppa, the PPA's verification key will be added automatically to the system.

When you add a repository as "Additional", like:
sudo sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list'
you would need to instruct the system explicitly to fetch and add the key:
wget -q -O - https://dl.google.com/linux/linux_signing_key.pub | sudo apt-key add -

This is probably why they show under two different tabs in Software Sources.

In this case, it is about an "Additional repository" and not a "PPA"

What are Repositories?

Hello, Mathews.

The content of the file should /etc/apt/sources.list.d/additional-repositories.list read

Code: Select all

deb https://dl.winehq.orq/wine-builds/ubuntu/ xenial main

I.e. the same malformed entry, malformed in different way partially, is present 3 times.
Keep only the first line and add the missing space before the nickname xenial.

Cheers,
Karl

[Sir Charles]

Nice catch, Karl!
Thanks!


deb https://dl.winehq.orq/wine-builds/ubuntu/ xenial main
