我想知道为什么upgrade有时不想升级系统的某些部分，而dist-upgrade确实如此。这是运行后的示例apt-get upgrade：
apt-get upgrade：
rimmer@rimmer-Lenovo-IdeaPad-S10-2:~$ sudo apt-get upgrade

The following packages have been kept back:

0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.

但是，我收到此错误：
corebird depends on libglib2.0-0 (>= 2.41.1); however:
Package libglib2.0-0:amd64 is not configured yet.
corebird depends on libgtk-3-0 (>= 3.13.7); however:
Version of libgtk-3-0:amd64 on system is 3.10.8-0ubuntu1.4.
因此，我尝试变得聪明并手动跟踪并安装这些库。我找到了正确的deb文件，但是当我跑dpkg -i了libglibDEB，我得到这个：
pkg: error processing package libglib2.0-0:amd64 (--install):
package libglib2.0-0:amd64 2.42.0-2 cannot be configured because libglib2.0-0:i386 is at a different version (2.40.2-0ubuntu1)
以及其他一些无法配置它的原因，因为 libglib2.0-0:amd64 是错误的版本。
这是我出错的地方。我想都没想就跑了sudo apt-get remove libglib2.0-0:amd64。
所以，很明显，它造成了大量的依赖问题，并告诉我运行sudo apt-get -f install. 我这样做了，现在我明白了：
sudo apt-get -f …我有一台配备 AMD Radeon Vega 卡的 ryzen 电脑，运行 ubuntu 22.04LTS，并且我正在尝试安装 amdgpu-install_22.10.2.50102-1_all 驱动程序，以便我可以使用 Blender 3.2 并获得 HIP 支持。然而，我过得很糟糕，我所有的努力都白费了。
当我运行命令时amdgpu-install -y --opencl=rocr
我得到以下输出：
linux-headers-5.15.0-40-generic is already the newest version (5.15.0-40.43).
linux-headers-5.15.0-40-generic set to manually installed.

Could not calculate the upgrade
An unresolvable problem occurred while calculating the upgrade.
起初，该错误给了我一个原因：我必须清除所有 Launchpad PPA。我这样做了，在仍然收到相同的错误后，我进行了一些搜索并找到了这个错误报告，其中一些用户说安装 clang-9 解决了这个问题。我自己这样做了，现在我得到了相同的错误，但有不同的解释：我“安装了预发布版本。这是一个暂时性问题。” 所以我删除了 clang-9，更新并自动删除了所有内容，现在我只是收到错误，根本没有任何建议的解释。
由于这个对话没有帮助，我跋涉到我的/var/log/dist-upgrade/main.log，在那里我看到了这一行：
ERROR Dist-upgrade failed: 'E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.'
然后我检查了apt.log以查看发生了什么。显然有相当多的错误。
我有哪些选择？如果您为“Broken”搜索此日志，则升级程序认为有很多软件包已损坏（尽管它们都没有显示在 dpkg 或 Synaptic 中），并且将它们全部删除是不可行的，我担心可能会破坏我的整体系统。根据问题包列表，我认为存在一两个关键包，修复将消除整个问题。我只是不确定它们可能是哪些。任何帮助将不胜感激。
我使用的是 Ubuntu 20.04。当我执行命令时：
sudo apt-get install build-essential

build-essential is already the newest version (12.8ubuntu1.1).
You might want to run 'apt --fix-broken install' to correct these.
