Boa noite a todos. Eu tenho um problema com o lançamento do software Ubuntu recentemente. Se eu tentar iniciá-lo em gui, não fará nada. Lançamento a partir de respostas do terminal com
$ ubuntu-software
(ubuntu-software:15217): Gs-WARNING **: failed to open plugin /usr/lib/gs-plugins-9/libgs_plugin_xdg_app_reviews.so: /usr/lib/gs-plugins-9/libgs_plugin_xdg_app_reviews.so: cannot open shared object file: No such file or directory
Eu tentei então
sudo apt-get install --reinstall ubuntu-software
mas não ajudou em nada.
Eu também segui algumas instruções e chamei o upddate
de forma inesquecível, não posso adicionar todo o resultado aqui, porque o site acha que sou um spammer, então adiciono a parte em que os erros começam a aparecer

Alguém pode ajudar?
