ubuntu故障

ubuntu出現錯誤:E: Problem executing scripts APT::Update::Post-Invoke-Success 'if /usr/bin/test -w /var/

解決方法:

在終端執行如下幾條命令：

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 問題即可解決。
