我使用 apt-fast 下载并安装软件包。我注意到 apt-fast 不会显示将下载多少数据,而 apt-get 会显示:
The following NEW packages will be installed:
dkms libgsoap2 virtualbox virtualbox-dkms virtualbox-qt
0 upgraded, 5 newly installed, 0 to remove and 6 not upgraded.
Need to get 19.9 MB of archives.
After this operation, 77.9 MB of additional disk space will be used.
从 apt-fast 安装时如何利用此功能?
