Hi

im a linux noob trying out and absolutely loving linux lite! I am not yet prepared to replace my win 10 with linux but soon i will. For now i am running it in virtualbox as a client os to my windows. I am trying to do a software update in linux lite and am getting this error:

W:The repository 'http://ppa.launchpad.net/noobslab/deepin-sc/ubuntu xenial Release' does not have a Release file., Wata from such a repository can't be authenticated and is therefore potentially dangerous to use., W:See apt-secure( 8) manpage for repository creation and user configuration details., E:Failed to fetch http://ppa.launchpad.net/noobslab/deepin...4/Packages  404  Not Found, E:Some index files failed to download. They have been ignored, or old ones used instead.

couldn't fetch the package cache information lists.

Seems you've added a PPA from noobslab, remove it. That's what's causing your problem.

Seems you've added a PPA from noobslab, remove it. That's what's causing your problem.

If you know what application is using that PPA, then i would uninstall it and the PPA first, then try an update.
After that, install the PPA from noobslab directly.  http://www.noobslab.com/    http://www.noobslab.com/p/ppa.html

Then install apps/programs from noobs website or command line.
Be very careful adding PPA's from unknown locations.
