Não consegui...
 Favor me dar a sequencia dos comandos para que eu possa copiar e colar no terminal...

Progredi ate aqui, me parece que consegui instalar os pacotes que estavam faltando, porem quando dei o comando make, o sistema deu outra informação de problema, veja abaixo o que apareceu no terminal:

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables PACKAGE_CFLAGS
and PACKAGE_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

Gostaria de saber se existe a possibilidade de que possamos dar prosseguimento, o digitalizador esta disponivel, contudo o driver ainda não foi instalado ou ainda não foi reconhecido.

Fui informado pelo site oficial da canon que para instalar o driver do digitalizador da multifuncional canon pixma mg2410 no linux mais especificamente no ubuntu 14.04 seria preciso fazer o download do arquivo scangearmp-source-2.20-1.tar.gz
Fiz o download e descompactei com o extrair aqui dentro da pasta download de modo a obter o arquivo descompactado scangearmp-source-2.20-1
Agora não sei como dar prosseguimento e por isso peço ajuda.
Preciso de ajuda bem detalhada para usar o terminal
Na expectativa de que possa ser atendido agradeço.
Minha multifuncional esta funcionado apenas para imprimir, não estou conseguindo usar o digitalizador.

A bateria do meu computador com sistema operacional Ubuntu 14.04 expirou e com isso uma serie de mensagens de erros começaram a aparecer na tela como "erro de sistema" etc. o mouse e o teclado com conexão usb pararam de funcionar! Como eu percebi que o relógio do computador estava sempre mostrando hora errada desconfiei que fosse a bateria do computador. Troquei a bateria acertei a hora na BIOS e quase tudo voltou ao normal. Somente consegui acessar trocando o mouse e o teclado por unidades PS2. Peço ajuda para que o computador possa reconhecer todas as entradas USB novamente.

Deu certo sim!
Apos as sugestões usei o sudo apt-get update e tudo ficou resolvido!
Foi realizada uma atualização normal!
Grato

Acho que fiz uma besteira tentando colocar o repositorio do medibuntu no ubuntu 14.04 recem instalado para tentar baixar outro programa que dependia do mediubuntu.
Ocorreu um erro e obtive as seguintes mensagens:
Um erro ocorreu por favor use o gerenciador de pacotes a partir do menu com um clique diereito ou use o apt-get em um terminal para ver o que esta errado
Usei o apt-get update e obtive a seguinte resposta:

[sudo] password for fruegger:

E: A lista de fontes não pode ser lida.

Não sei como corrigir esse problema! Peço ajuda!
