I have tried to install Gparted with Software Center and it shows an error:
"Requieres installation of untrusted packages: this action would require the installation of packages from not authenticated source. "
In "Edit>Software Sources" I have checked the following options:
officially supported (main)
- DSFG-compatible
- Software with Non-Free Dependencies (contrib)
- Non-DSFG-compatible
- Software (non-free)
- Source code
When I close the options windows it says:
"Failed to download repository information. Check your Internet connection."
Other form (and the easiest) through terminal:
teo@manipulation:~$ sudo apt-get install gparted
[sudo] password for teo:
Reading package lists... Done
Building dependency tree
Reading state information... Done
N: Ignoring file 'google-chrome.list.save' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
E: Unable to locate package gparted
Then, I have tried to update the packages list with "sudo apt-get update" but it shows this error:
teo@manipulation:~$ sudo apt-get update
