执行apt-mirror。
由于apt-mirror可能有bug，所以可能需要手动下载icon64x64@2.tar.gz文件。
cd <apt-mirror-home>/mirror/archive.ubuntu.com/ubuntu/dists
for dist in bionic bionic-updates bionic-security; do
for comp in main multiverse universe; do
for size in 48 64 128; do
wget http://archive.ubuntu.com/ubuntu/dists/${dist}/${comp}/dep11/icons-${size}x${size}@2.tar.gz -O ${dist}/${comp}/dep11/icons-${size}x${size}@2.tar.gz;
