Tenta: sudo apt autoremove -y && sudo apt autoclean && sudo apt update && sudo apt full-upgrade -y
Se não funcionar, é problema com os espelhos que você está usando. Ou você espera voltar ao normal ou muda para outro que seja próximo também.

Para mudar de mirror:
1- Software & Updates;
2- Na aba “Ubuntu software”, selecione o servidor que preferir em “Download from”

O xubuntu estava me dando muita dor de cabeça, fiz os comandos e não funcionou, mudei os espelhos e também não funcionou, então mudei para o Mint Xfce e até agora nenhum problema!
