I use apt-fast to download and install packages on my system. What I have noticed is apt-fast does not show me how much data will be downloaded, as apt-get does:
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.
How can I avail this feature when installing from apt-fast?
