Ubuntu 24.04.1-libsasl2-dev 的依赖问题[重复]

  • 772

我正在尝试在我的笔记本电脑（Ubuntu 24.04.1 LTS）上安装libsasl2-dev。但是，当我运行命令时

sudo apt install libsasl2-dev

我收到一条错误消息：

The following packages have unmet dependencies:
 libsasl2-dev : Depends: libsasl2-2 (= 2.1.28+dfsg1-5ubuntu3) but 2.1.28+dfsg1-5ubuntu3.1 is to be installed
E: Unable to correct problems, you have held broken packages.

有任何调试或潜在修复的建议吗？我尝试搜索，但找不到任何相关内容...

apt
