apt sources.list disabled on upgrade to 12.04
- by user101089
After a do-release-upgrade, I'm now running ubuntu 12.04 LTS, as indicated below
> lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 12.04 LTS
Release: 12.04
Codename: precise
However, I find that all the entries in my /etc/apt/sources.list were commented out except for one.
QUESTION: Is it safe for me to edit these, replacing the old 'lucid' with 'precise' in what is shown below?
