Today i installed fresh ubuntu linux on my acer aspire v5 , very old laptop, dual boot with windows 8.1. Since i cannot connect to internet via wire, i had to download drivers from internet, and install them manualy. i downloaded b43-fwcutter amd64, and firmware b43 installer, both in .deb file and wanted to install via console first, sudo apt install b43-fwcutter_019-4amd64 with and without .deb on the end. ( sorry im linux noob atm ) but i got error that package is not found, same with firmaware-b43-installer.deb. when i tried simply click on the icon, and install it via software installer, installation stuck on "pending" and start working again. Any clue how to fix that ? i installed 64 bit system, from live pendrive.
