Ubuntu 16.04:Problemexecuting scripts APT::Update::Post-Invoke-Success 'if /usr/bin/test -w/var/cache/app-info -a -e /usr/bin/appstreamcli; then apapstreamcli refresh> /dev/null; fi'
Reading package lists... Done
E: Problem executing scriptsAPT::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 anerror code
在运行sudo apt-get update时出现如上信息，解决方法如下：
#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
执行完上述命令之后再次运行sudo apt-get update就不会再出现上面的错误。
