[Solved] CentOS7 Gnome Desktop Shell Extension Installation Error

I used Shell mode before and didn’t study the Gnome desktop very much. Today, I reported an error when I opened the Application >> System Tools >> Application Installer interface. According to the prompt information, combined with the cases on the Internet (the names of the shell script plugins given by many blog posts are wrong, but fortunately, the ideas can be used for reference), the solution ideas will be sorted out and recorded here.

2. Install the Gnome extension

2.1, install through the YUM library

2.2, install through the GNOME plugin market

Running Environment:CentOS-7.9.2009-x86_64

1, error message

Open Applications >> System Tools >> Application Installer The interface reports an error:

Failed to download update from “extensions.gnome.org”: [*/*/*/source/shell-extensions/*] failed to download https://extensions.gnome.org//static/extensions.json: SSL handshake failed

Failed to download update from “odrs.gnome.org”: [*/*/*/source/odrs/*]failed to download https://odrs.gnome.org/1.0/reviews/api/ratings: SSL handshake failed

According to the prompt information, combined with the online case, it can be seen that the gnome-shell plug-in is missing.

2. Install Gnome Extensions

2.1, installed through YUM library
