Olá. Eu acho que talvez não seja um problema exclusivo meu mas de todos os usuários do Ubuntu 22.04. Cheguei a essa conclusão lendo este artigo aqui: https://sempreupdate.com.br/distribuicao-ubuntu-linux-22-04-2-lts-so-deve-sair-no-final-de-fevereiro-devido-a-problemas-de-kernel/.
Vou esperar até 23/02/23 para ver se o problema persiste.

Olá. Quando eu rodo o Atualizador de Programas  do Ubuntu recebo a informação de que  " Os programas neste  computador estão atulizados" .Porém, quando uso o Synaptic e/ ou o terminal a informação é que existe uma serie de pacotes pra atualizar.  Fiquei com medo de tentar atualizar e dar problema. Isso é normal? Como devo proceder? .

Ok. Obrigado.  Mas acho que vou ter que esperar algum tipo de engenharia reversa para um genérico do driver da Samsung. Paciencia.
