Malformed entry in sources.list error in Ubuntu

rabin_computers · February 16, 2021, 1:33pm

I face that issue whenever i install any application

There is obviously something syntactically wrong with your list of sources.

Would you mind sharing the file in question? /etc/apt/sources.list.d/erlang-solutions.list

rabin_computers · February 16, 2021, 1:39pm

erlang was and environment i used while working on assignment, I can locate it since i installed it on terminal

rabin_computers · February 16, 2021, 1:40pm

#LOCK FILES
would this be the reason since i disabled on this process?

Akito · February 16, 2021, 1:41pm

Could you please follow @Mina’s request?

rabin_computers · February 16, 2021, 1:42pm

how do i share it @Akito?

rabin_computers · February 16, 2021, 1:43pm

how do i share this file please?

Akito · February 16, 2021, 1:46pm

sudo printf "$(</etc/apt/sources.list.d/erlang-solutions.list)"

rabin_computers · February 16, 2021, 1:49pm

They give me this…

It’d be nice if you copy-pasted the output here, verbatim.

It looks like there are 2 spaces between “debian” and “contrib”. It should be only a single space, I think.

rabin_computers · February 16, 2021, 1:58pm

that’s the output and it persists

rabin_computers · February 16, 2021, 1:59pm

I’m trying to edit root files, but i can’t the line with errors

rabin_computers · February 16, 2021, 2:04pm

#Someone help me identify the error line here

rabin_computers · February 16, 2021, 2:05pm

##additional part of it

You should not do that, if you have no idea what you are doing.

Especially #2) and #3) are important for you, right now.

The error might also be in the original sources file /etc/apt/sources.list.
You might want to copy and paste the output of grep -1 erlang /etc/apt/sources.list

Please do not post screenshots. Text is far easier to read.
It is a good idea to enclose the output lines in tags:

<pre>
text
</pre>

Okay thanks,

 E: Malformed entry 3 in list file /etc/apt/sources.list.d/erlang-solutions.list (Component)
 E: The list of sources could not be read.
The result when i try to update without editing anything in the root file

Mina · February 16, 2021, 2:22pm

This is most certainly not the output of the grep command.

Hi @rabin_computers,

When you tried installing Erlang, you added the repository meant for Debian.

In addition to that, the repository is also not in correct form (probably there is a missing term between debian and contrib) which is why it complains.

Here’s what you should be doing instead:

Remove the file or rename it something like this:

sudo mv /etc/apt/sources.list.d/erlang.solution.list /etc/apt/sources.list.d/erlang.solution.back

And then follow the steps mentioned here:

Hi Bro,

How did you enter the command in a different font that looks like the one in terminal (monospace font)? Please tell me about it… Your reply would be helpful.
