E:Problem executing scripts APT::Update::Post-Invoke-Success 'if /usr/bin/test -w /var/cache/app-inf

问题描述;

在ubantu 16.04 版本安装docker时,执行sudo apt-get update更新软件源,报错:

解决:

我的ubantu是64bit,在命令窗口按照顺序执行以下命令即可:

①sudo pkill -KILL appstreamcli

②wget -P /tmp https://launchpad.net/ubuntu/+archive/primary/+files/appstream_0.9.4-1ubuntu1_amd64.deb https://launchpad.net/ubuntu/+archive/primary/+files/libappstream3_0.9.4-1ubuntu1_amd64.deb

③sudo dpkg -i /tmp/appstream_0.9.4-1ubuntu1_amd64.deb /tmp/libappstream3_0.9.4-1ubuntu1_amd64.deb
