Ubuntu 16.04 出现E: Problem executing scripts E: Sub-process returned an error code处理办法

E: Problem executing scripts APT::Update::Post-Invoke-Success'if /usr/bin/test -w /var/cache/app-info -a -e /usr/bin/appstreamcli; then appstreamcli refresh > /dev/null; fi'E: Sub-process returned an error code

出现以上错误有一段时间了，虽然很久了，但是一直没处理。

亲测有效：

sudo pkill -KILL appstreamcli

wget -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

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