我正在尝试删除一个明显损坏的包gammu-smsd.service。
当我运行时sudo apt remove gammu-smsd.service，我得到以下结果：
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package gammu-smsd.service
我当时想删除这个包，因为在进行清理时，我在尝试安装和删除我选择的包时遇到了问题。这是升级的结果（更新没有问题）。
这是运行的结果sudo apt upgrade。

上面的输出结果中第 6 行提醒我出现了问题。当我得知罪魁祸首是时gammu-smsd.service，我运行了systemctl status gammu-smsd.service获得这个结果：

答案1
似乎有一个针对此问题打开了错误并且它在下一个版本中被修复了，但由于某种原因，它还没有发布 20.04，因此运行以下命令来修复该问题：
sudo sed -i 's|${CMAKE_INSTALL_FULL_BINDIR}|/usr/bin|g' /lib/systemd/system/gammu-smsd.service
最后，重新加载 systemd 并重新启动服务：
sudo systemctl daemon-reload
sudo systemctl restart gammu-smsd
解释：
问题似乎已在您的错误中指出。错误指出文件第 9 行指示的路径/lib/systemd/system/gammu-smsd.service未定义。
因此，要找到的路径gammu-smsd，您可以使用命令which gammu-smsd。
然后，您只需要编辑文件并用绝对路径/lib/systemd/system/gammu-smsd.service替换变量，这就是上面的命令所做的。${CMAKE_INSTALL_FULL_BINDIR}/usr/binsed
