Hello , first of all I am new to Ubuntu and last week I got a message from synaptic package manager to said they was up date available , so I updated my Ubuntu and now I have this message and I don t really know how to fix this , so if anyone can help that will be great , keep in mind I am new to Linux so if you can explain step by step that will be appreciate .
this is the problem from:
synaptic package manager :Could not download all repository indexes
The repository may no longer be available or could not be contacted because of network problems. If available an older version of the failed index will be used. Otherwise the repository will be ignored. Check your network connection and ensure the repository address in the preferences is correct.
Failed to fetch http://ppa.launchpad.net/tldm217/tah...source/Sources 404 Not Found
Failed to fetch http://ppa.launchpad.net/tldm217/tah...-i386/Packages 404 Not Found
Some index files failed to download. They have been ignored, or old ones used instead.
well that the message I get and to be honest it s does not really help me but to tried to fix it , I hope one of you can make something of this .
thank you for your help
