regarding vmware linux code compilation .
“sudo apt-get moo” is working and it is so cool. But “aptitude moo” is not working to me in the vmware linux console. Could anyone please get me out of this problem.
The error it was show is “you need to install aptitude”
I have tried to install but where at some point it is also asking like paste the above url by going into “media/cdrome” how can i find this media/cdrome in virtual machine vmware settings???
Thanks in advance for helping me.
You may need to update your sources first:
Try
sudo apt-get update
Then,
sudo apt-get -y install aptitude
Sir, thank you for your response. Actually i 've tried these two command lines to get updated but my terminal is completely filled with errors , I mean it’s showing errors.
What kind of errors?
Click on install tools in the bottom of the scree.
In the terminal press enter. OR
press y as it is asking you to use additional space
Open and modify the file /etc/apt/sources.list
Type-
vi /etc/apt/sources.list
or
sudo gedit /etc/apt/sources.list
In the output , you will get a list of all package sources.
You might find a line something as
deb cdrom:[Ubuntu 16.04.6 LTS…]/ main
This is a line indicating a local CDROM as a package source.
Comment it out by placing a # symbol at the beginning of the line and save the file.
# deb cdrom:[Ubuntu 16.04.6 LTS…]/ main
Save the file and run :
sudo apt -get update

Sir, I have got the output exactly what you have shown but I am unable to make that line as comment by adding hash in the starting position. Sir I am unable to write anything on the terminal file 
Sir could you please help me out of this problem 
Try
sudo nano /etc/apt/sources.list
Type ‘apt moo’ instead of ‘aptitude moo’.
