I am following this guide to install ruby on rails to work with Apache and Passenger. I have followed it step for step and done every command in verbatim. Soon after running

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

and inserting

deb https://oss-binaries.phusionpassenger.com/apt/passenger trusty main

I received this error on my toolbar:

enter image description here

I tried to delete the file but it can't be deleted. Can I fix this?

  • Have you tried running sudo apt-get update and sudo apt-get install -f?

  • I have attempted both of those commands and the error still persists

Plan A:

Running:

sudo apt-get update

Then:

sudo apt-get install -f

Installing any unmet dependencies, and possibly then doing a restart should fix it.

Plan B:

Otherwise you should edit the file with:

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

Once more and remove the line you added, then save the file and run:

sudo apt-get update

And the error should be gone (although a restart may also be necessary for the error to go away as I often find this is necessary even after the problem itself is fixed).

Plan C:

And finally if all of that failed, delete the file. As this file will be owned by root, you will need to use sudo to raise your privileges in order to delete it:

sudo rm /etc/apt/sources.list.d/passenger.list

The file should now have been removed, so run:

sudo apt-get update

And now the error should be gone.

  • Man, Plan B was so easy, how did I not think of that? Thank you very much!

  • Just to throw this in for anyone else who runs into this guide and gets the same error... I had to change the file permissions to delete the file. Simply removing the line didn't solve the problem.

  • @ZachLandry: Ok, I have added that as Plan C... ;D
