重复错误：无法安装 desktop-icons@csoriano

我遇到了同样的问题，并通过desktop-icons@csoriano使用他们的 git 存储库手动重建文件夹来修复它。

显然，您不能真正从系统desktop-icons@csoriano中删除和其他扩展。/usr/share/gnome-shell/extensions/Ubuntu 20.04 预计它们将在全球范围内存在。在我看来，他们的更改只能被其他（全局和本地）扩展主动覆盖。另一种方法是重建一个“修改”版本的扩展，它根本什么都不做。

/usr/share/gnome-shell/extensions/desktop-icons@csoriano/以下是删除后完全重建原始文件的步骤：

# Corona-like I stayed at home for this. You can also do this in another location, doesn't matter much for the following steps...
cd ~
# Install the building tools used by the makers of desktop-icons@csoriano
sudo apt update
sudo apt install meson git
# Clone their repository to ~/desktop-icons/.
# MAKE SURE there is no file or directory in home called "desktop-icons"!
git clone https://gitlab.gnome.org/World/ShellExtensions/desktop-icons
# Enter the cloned repository.
cd desktop-icons
# Prepare building the extension using meson.
# This will set the location of the build in it's config. So even if /usr/ is a root location, we don't need sudo for now.
meson --prefix=/usr/ --localedir=share/gnome-shell/extensions/desktop-icons@csoriano/locale .build
# Build the extension. You can execute this using sudo, otherwise you'll be asked for the root password by ninja.
ninja -C .build install

# We're technically done. Now let us clean up what we needed for the above.
# Remove the cloned repository.
rm -rf ~/desktop-icons/
# Remove building tools. You can keep these packages if you like, but they aren't needed for the extension anymore.
sudo apt remove meson git
sudo apt autoremove

# Apply changes (you might do that after you continued reading this post to the end).
# Alternatively you can just restart gnome, for that see https://stackoverflow.com/q/46565019/7638119
sudo reboot

有关更多信息，并且如果您在执行这些步骤时遇到问题，请访问官方存储库以及他们的问题页面。

以下是修改扩展的步骤，使其不执行任何操作：

cd /usr/share/gnome-shell/extensions/desktop-icons@csoriano
# empty its entry script
sudo mv extension.js extension.js.old
sudo touch extension.js

（这可能会导致 Ubuntu 20.04 的未来更新出现问题。要撤消此修改，只需运行cd /usr/share/gnome-shell/extensions/desktop-icons@csoriano; sudo mv extension.js.old extension.js。）

您可能会遇到这种情况，因为您按照官方解决方法通过安装 nemo来修复 Ubuntu 20.04 的桌面图标，就像我一样。我强烈建议您撤消此操作并等待官方补丁。可以在 launchpad.net 上查看补丁更新。在那里也可以看到其他解决方法。

如果您想卸载nemo并等待问题的官方补丁，请反向执行替代安装：

# Remove nemo from local autostart.
rm ~/.config/autostart/nemo-autostart-with-gnome.desktop
# Remove the nemo package.
sudo apt remove nemo
sudo apt autoremove

# Apply changes.
# Alternatively you can just restart gnome, for that see https://stackoverflow.com/q/46565019/7638119
sudo reboot

**** 在“软件和更新”中，我启用了 (main)、(Universe)、(restricted) 和 (multiverse)*** 它需要启用 Universe 包，如果不需要，可以在安装后禁用它

解决方案 1:: 尝试使用命令重新安装

sudo apt install gnome-shell-extension-desktop-icons

然后重启..

解决方案 2::如果已安装且无法使用， 请先尝试删除软件包

sudo apt purge gnome-shell-extension-desktop-icons
                      or
sudo apt remove gnome-shell-extension-desktop-icons

然后再次使用

sudo apt install gnome-shell-extension-desktop-icons

然后重新启动.. 希望这有帮助

但是这个扩展在从桌面拖放时会导致问题，所以如果你需要从桌面拖放，请卸载它并使用扩展 https://extensions.gnome.org/extension/2087/desktop-icons-ng-ding 不要忘记使用删除扩展后重新启动

sudo apt purge gnome-shell-extension-desktop-icons
                   or 
sudo apt remove gnome-shell-extension-desktop-icons

对我来说，安装gnome-shell-extension-desktop-icons-ng是为我解决的问题。
