我最近开始遇到软件更新程序问题。当我尝试运行它时，我收到以下消息：
Failed to download repository information. Check your internet connection.
我的连接工作正常，所以我确信一定是别的原因。下面是详细信息输入作为代码的输出，因为这是我能找到的唯一允许我将其包含在内的方式。

运行以下命令没有产生任何输出。
grep -i 1386 /etc/apt/sources.list
grep -i 1386 /etc/apt/sources.list.d/*.list
答案1
您的计算机设置的架构类型不正确。
在terminal...
让我们看看现在有什么...
sudo dpkg --print-architecture
# could show amd64
sudo dpkg --print-foreign-architectures # note the ending s
# could show 1386 <-- this is the bad one
让我们解决这个问题...
sudo dpkg --remove-architecture 1386 # delete the bad one
sudo dpkg --add-architecture i386 # add a good one
更新＃1：
该错误E:Failed to fetch http://ppa.launchpad.net/pcf/miro-releases/ubuntu/dists/xenial是因为不存在 xenial 存储库。
在terminal...
cd /etc/apt/sources.list.d
grep -i miro-releases *.list
# note the filename that is returned
gksudo gedit /etc/apt/sources.list.d/{enter found filename here}
# comment out the deb lines by placing a # at the beginning of the lines
# save the file and quit gedit
