Posted: 2017-08-23 07:39
Hi,
I'm trying to update my system but I keep getting errors. When I run "apt-get update" I get the following errors:
My sources.list contains the following lines:
My other sources are:
/etc/apt/sources.list.d/
├── google-chrome.list
├── google-chrome.list.save
├── skype-stable.list
└── skype-stable.list.save
google-chrome.list content:
skype-stable.list content:
I tried many methods I found on internet but none of them solves the problem. What can I do to fix it?
Thanks
