parece que o dpkg está meio quebrado, você poderia tentar.
sudo apt-get install --reinstall dpkg
py3compile: not found
O comando py3compile faz parte do pacote python3-minimal que parece estar corrompido.
Para corrigir o problema, tente o seguinte:
Corrija um sistema com dependências quebradas no lugar:
sudo apt-get -f install
Reconfigure todos os pacotes descompactados, mas não configurados, por:
sudo dpkg --configure -a
Se acima não ajudar, tente reinstalar python3-minimal package por:
sudo apt install -f --reinstall python3-minimal
Alternativamente, execute:
apt-get download python3-minimal
sudo dpkg -i *python3*.deb
sudo apt install -f
Ou faça o download do .pkg arquivo do kernel.org e instale a partir de o arquivo por:
sudo dpkg -i python3-minimal_*.deb
Em seguida, certifique-se de que os comandos py3compile e py3clean sejam executáveis e sejam acessíveis a partir da variável PATH .
