Q. I want to delete some file

uConsole
1

There was a problem while installing a program called qmmp.
mp3 is playing, but there is no sound, so I delete the program,
I tried to install another program, but sudo apt update didn’t run.
(Picture 1) If you look at the sentence, it seems that there is an error related to the list,
When I went into the folder called (picture2) /etc/apt/sources.list.d/ and checked the contents of the file, I thought it was an error due to ['], so I tried to edit the file, but it didn’t work,
(Picture3) I tried to delete a file called volian.list, but it didn’t,
(Picture4) I tried to fix and delete the permissions for that file, but the permissions were not modified.

How can we fix the problem?
The location of the file is /etc/apt/sources.list.d/volian.list

What’s in the file
'dev https:://deb.volian.prg/volian/ raspbian main ’
It is written that.

Should I format and refresh again? Please help.

Added. Has anyone installed an mp3 player called qmmp and experienced no sound? Why can’t I hear the sound..

take the ’ off the beginning and end in that file. The line should look like this:
[edit: also should say “deb” not “dev” ]

deb https:://deb.volian.prg/volian/ raspbian main

You will need to edit the file as root (or sudo).

I don’t have my machine in front of my to test, but press Alt+F2 to run a custom command. Then

gedit admin:///etc/apt/sources.list.d/volian.list

Or from a terminal (if you’re comfortable using that):

sudo nano /etc/apt/sources.list.d/volian.list

  • now : It worked normally when inputted directly at the terminal

sudo apt update
sudo apt-get install qmmp

its already solved, but to remove a file you need the “rm” command. Depend on the file you may need to sudo it
I.E
rm /directory/file
sudo rm /directory/file

If you want to delete a folder you need to include -r
rm -r /directory
sudo rm -r /directory
