CodingTeen2017's questions

I am currently taking a Controlled Assessment, and this is one of the tasks.

Make sure that you have the program traceroute installed. (Install it if necessary.)

I went on https://www.codeground.net/howto/traceroute-is-not-installed-by-default-on-ubuntu-replaced-by-mtr/, and it told me to use sudo apt-get install traceroute,so I tried that, but it comes up with an errror message when I try it.

If you have any solutions I would be very grateful! :-)

Edit: I just used anand's answer, but it says:

E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied) E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

I am unaware of what this means, so can someone please help.

Edit 2:I tried anand's updated answer, but the error message that comes up is:

Some index files failed to download. They have been ignored, or old ones used instead.

Edit 3: anand told me to add the logs, so here they are.

I'm trying to do this part of my assessment:
Show and explain the contents of the profile file.

But I cannot open it. I tried ls- profil, but that didn't work.

Edit: Melebius helped me to find the answer. Thanks dude!
