安装ubuntu桌面系统报错：libmutter-10-0 : Breaks: libgtk-4-1 (＜ 4.6.3+ds1-0ubuntu1~) but

issue:

when installing GUI environment:

# apt-get update
# apt-get install ubuntu-desktop #安装桌面软件

Installation fails due to broken libmutter-10-0 dependency -

The following packages have unmet dependencies:
 libmutter-10-0 : Breaks: libgtk-4-1 (< 4.6.3+ds1-0ubuntu1~) but 4.6.2+ds-1ubuntu2 is to be installed
E: Unable to correct problems, you have held broken packages.

1. One workaround is to wait 2 days for the new gtk4 version to fully phase.

2. Another is to do something like this:
Create a file /etc/apt/apt.conf.d/phased

with this content:

APT::Get::Always-Include-Phased-Updates "true";

Run sudo apt update and then do whatever you were trying to install/upgrade.

I recommend removing that file afterwards since the bugfix for apt is in progress and the phased updates feature is a good idea.
