Gnome-调整"Gnome shell不运行“

Question

从昨天开始，我一直在尝试运行和安装GNOME微调，但是它告诉我它已经存在了。但是shell没有运行：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
gnome-tweaks is already the newest version (3.34.0-3).
0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded.

当我尝试手动打开它时，我无法找到它。

所以我尝试使用终端打开，这就是所发生的事情：

Answer 1

下载此文件：

http://ports.ubuntu.com/pool/universe/g/gnome-tweak-tool/gnome-tweak-tool_3.18.1-1_all.deb

然后：

sudo apt install gdebi

然后尝试使用Gdebi安装它：

sudo gdebi gnome-tweak-tool_3.18.1-1_all.deb

Answer 2

通过简单地删除gnome-tweaks，然后重新安装它，我解决了这个问题：

sudo apt remove gnome-tweaks 
sudo apt autoremove 
sudo apt install gnome-tweaks
