I have just upgraded Linux Mint here; previously I was having version 9 and now I have version 10 here. Well the upgrade just went smooth and not with bigger issue as such. Now the thing is that after successful upgrade I cannot install the new packages here on my system. Also I cannot have the system updates also here. Whenever I try to do this I have seen that I keep getting the following message there: E: firmware-b43-installer: subprocess installed post-installation script returned error exit status 1. Can anyone here please help me with the situation here?
