錯誤而instaling的Percona

Question

我用這個命令

wget https://repo.percona.com/apt/percona-release_0.1-4.$(lsb_release -sc)_all.deb 
dpkg -i percona-release_0.1-4.$(lsb_release -sc)_all.deb 

sudo易於得到更新 和得到這個錯誤

N: Ignoring file 'percona-release_0.1-4.xenial_all.deb' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension

我用https://www.percona.com/doc/percona-server/LATEST/installation/apt_repo.html教程和虛擬ENV。錯誤在哪裏以及如何解決？

輸出顯示您已經在/etc/apt.sources.d之內離開了Percona版本.deb文件 - 掃描目錄中的文件。 將它從該文件夾移出到其他地方，關於Percona版本的消息將消失。

您涉及到您已安裝的PPA（與Percona存儲庫無關）的錯誤。您可以找到有關how you can remove it的信息，其中一個選項是sudo add-apt-repository --remove ppa:whatever/ppa
