I have tried to excute sudo apt-get update command but it return below error:

E: Failed to fetch http://ppa.launchpad.net/upubuntu-com/web/ubuntu/dists/xenial/main/binary-amd64/Packages  404  Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.

Please provide solution. as I am not able to install other packages due to the error.

  • This doesn't mean that you are "not able to run apt-get update". This shows that one of the PPAs doesn't exist. – Pilot6 Mar 13 '19 at 08:54
  • @Pilot6, Did you see the package name in my question? – Dev Ramesh Mar 13 '19 at 08:56
  • This package is not exit. http://ppa.launchpad.net/upubuntu-com/web/ubuntu/dists/xenial/main/binary-amd64/Packages

    i know, if any package is not exist, we can remove from sources.list file. but i didn't find this package in the file or software & update

  • I don't see any package names. But this error doesn't affect your ability to install anything. What are you calling "this package"? – Pilot6 Mar 13 '19 at 08:58
  • Why don't you ask what are you trying to do? – Pilot6 Mar 13 '19 at 09:08

The error tells that the repository doesn't exist (or that there is a spelling error in the url - ending up in the same not found situation). It doesn't stop you from upgrading your software or installing new. Just run sudo apt-get upgrade or sudo apt-get install <some package>.

To get rid of the error find and comment out (by adding a # in front of the line) the line in /etc/apt/sources.listor in one of the files (if any) in /etc/apt/sources.d

  • Can you provide working URL for this package. http://ppa.launchpad.net/upubuntu-com/web/ubuntu/dists/xenial/main/binary-amd64/Packages – Dev Ramesh Mar 13 '19 at 09:03
  • This is not a package. This is an URL. – Pilot6 Mar 13 '19 at 09:06

    @DevRamesh it's a repository that apparently doesn't contain packages for versions more recent than Precise (Ubuntu 12.04) – steeldriver Mar 13 '19 at 09:08
  • I have no idea what package it is. You (or your system admin) have added the repository to gain access to a software product. You - or he - knows. – Soren A Mar 13 '19 at 09:09
