Estava tentando remover a versão 3.8 do python já que não tinha nenhum dependência ligada a ele e eu queria usar o python3.7 e tava dando um problema ou conflito que tava instalando o que eu queria na versão 3.8. Bem, vi uma solução que seria alterar o python padrão, fiz isso e alterei para o python3, mas aparentemente alterou um monte de dependência e não consigo desfazer isso, já procurei umas soluções mas nenhuma funcionou. Não consigo fazer aparentemete nada, só consigo abrir o terminal se eu for numa pasta e abrir o terminal na pasta, já que pelo atalho não funciona, nem na interface gráfica, o Software & Updates também não está abrindo, tentei reinstalar, mas não consegui instalar, não consigo fazer o update nem instalar nada no meu ubuntu. Se alguém puder me ajudar, eu agradeço.
Ubuntu 18.04.4 LTS

Quando eu tento fazer o update:

jose@jose-pc:~$ sudo apt update

Aparentemente consegui resolver, vi que tinha uns pacotes que dependiam de outros que não estavam configurados:

apturl-common
software-properties-common
apturl
software-properties-gtk
gnome-software
gnome-software-plugin-snap

Então eu fiz:

sudo dpkg --configure apturl-common

E isso me resultou:

Setting up apturl-common (0.5.2ubuntu14.2) ...

/var/lib/dpkg/info/apturl-common.postinst: 27: /var/lib/dpkg/info/apturl-common.postinst: py3compile: not found

dpkg: error processing package apturl-common (--configure):

 installed apturl-common package post-installation script subprocess returned error exit status 127

Errors were encountered while processing:

 apturl-common

 

Então usei:

sudo apt install -f --reinstall python3-minimal
sudo apt-get update

E isso corrigiu o erro.

Depois reinstalei:
apturl-common
software-properties-common
apturl
software-properties-gtk
gnome-software
gnome-software-plugin-snap

sudo apt install -f --reinstall <package>
sudo apt update

Pq não usar:

 $apt-rdepends 

ou

$apt-cache depends --recurse --no-recommends --no-suggests --no-conflicts --no-breaks --no-replaces --no-enhances vim | grep "^\w" | sort -u | column 

saída do comando: (como exemplo segue as dep das dep do vim)
Mas cuidado, nem todas são requeridas para instalação do vim, é só um exemplo.

Não conheço muito de lixus, então fui só lendo o que ia aparecendo dos erros e corrigindo. Pois tentei corrigir os pacotes quebrados e não tinha funcionado. Mas agradeço pela ajuda, não conhecia esses comandos.
