从 16.04 到 18.04 的依赖关系损坏（libpangoft2-1.0.so.0 中的 hb_font_funcs_set_variation_glyph_func 的符号查找错误）

我一直在分阶段升级我的操作系统，以达到最新的 LTS 版本。昨天，我按照此处帖子中的建议，在运行“sudo apt-get update; sudo apt-get upgrade; sudo apt-get dist-upgrade”后，运行了“do-release-upgrade”。升级后，出现了许多损坏的依赖关系。

现在，突触，apt-get， 和软件属性-gtk并且许多其他重要程序将无法运行，并产生此错误：

synaptic：符号查找错误：/usr/lib/x86_64-linux-gnu/libpangoft2-1.0.so.0：未定义符号：hb_font_funcs_set_variation_glyph_func

apt --fix-broken install或等命令sudo apt-get install -f以及其他常用建议均未解决问题。还有其他策略可以尝试吗？

$ which synaptic
/usr/sbin/synaptic

$ dpkg -S $(which synaptic)
synaptic: /usr/bin/synaptic

$ ldd $(which synaptic) | grep local
# produces no result.

答案1

该问题的解决分为多个步骤：

  1. 安装所有升级，无需删除软件包

    sudo aptitude safe-upgrade

  2. 删除重复的/usr/lib/gdk-pixbuf-2.0/2.10.0/loaders触发器/var/lib/dpkg/triggers/File

要安装所有升级，我建议运行

sudo apt-get update
sudo apt-get dist-upgrade
