Comment 8 for bug 1200775

It is the first time I try "apturl" on this computer ( i386/686, 32 bits )since I have lost the possibility to access
" ubuntu software-center ", about 2 weeks ago, just after one update.
I can't install any .deb, unless the " synaptics ) ones.
Sure I have done somme mistakes .What can I do ?
Note : My second computer ( i86_64 ) works perfectly with " software-center ".
Excuse my scolar English.
