我怎样才能纠正这个问题.. ?? 执行＆＃34; sudo apt-get update＆＃34;之前＆＃34; sudo apt-get upgrade＆＃34;

   W: The repository 'http://ppa.launchpad.net/fkrull/deadsnakes -
   python2.7/ubuntu xenial Release' does not have a Release file.
   N: Data from such a repository can't be authenticated and is 
   therefore potentially dangerous to use.
   N: See apt-secure(8) manpage for repository creation and user 
   configuration details.
   E: Failed to fetch http://ppa.launchpad.net/fkrull/deadsnakes  -
   python2.7/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.

您是否尝试'更新'生成'升级'？

如果没有，请尝试sudo apt-get update然后sudo apt-get upgrade

这将在升级之前更新可用软件包列表。

在Ubuntu 16.04（LTS）中进行sudo apt-get升级时出错
