将我的 Ubuntu 从 18.10 升级到 19.04 后，一些软件包被保留了下来，但我并不在意，因为我认为这些问题将在几周内得到解决，届时依赖项将可以升级到适合我的操作系统的版本。过了一段时间，情况并没有发生，我仔细研究了这些“被保留”的软件包，发现了一个问题，这也解释了为什么我的系统负载指示器小部件和其他依赖传感器的小部件停止工作。
只剩下 2 个包被阻止了：libsnmp30 sysstat。两者都以某种方式依赖于 ，而后者libsensors5又依赖于libsensors-config。现在我可以尝试libsensors-config通过安装sudo apt install libsensors-config，但我得到的（最后）输出让我认为这不是一个好主意，对吗？

尝试“手动”下载并安装后，我得到了以下信息libsensors5：dpkg

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies.
libgl1-mesa-dri : Depends: libsensors4 (>= 1:3.0.0) but it is not installable
libsnmp30 : Depends: libsensors4 (>= 1:3.0.0) but it is not installable
sysstat : Depends: libsensors4 (>= 1:3.0.0) but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

而我仍然保留着相同的包裹。sudo apt upgrade给出了与相同的输出sudo apt -f install。
不过现在libsensors5好像libsensors-config已经安装好了？

新的问题是我现在无法通过它安装任何软件包，apt因为它总是告诉我修复依赖性问题，apt --fix-broken install但这没有任何帮助/修复任何问题。

答案1
因此，您有libsensors4一个与 冲突的包libsensors-config。libsensors4甚至不在 Disco 的包存储库中。因此，您需要用libsensors4替换libsensors5：
sudo apt update
wget http://mirrors.kernel.org/ubuntu/pool/main/l/lm-sensors/libsensors-config_3.5.0-3ubuntu1_all.deb
wget http://mirrors.kernel.org/ubuntu/pool/main/l/lm-sensors/libsensors5_3.5.0-3ubuntu1_amd64.deb
sudo dpkg -i --force-all libsensors-config_3.5.0-3ubuntu1_all.deb libsensors5_3.5.0-3ubuntu1_amd64.deb
sudo apt remove libsensors4
sudo apt -f install
更新 1：
打开sources.list：
sudo gedit /etc/apt/sources.list
删除那里的所有内容并添加以下行：
deb http://archive.ubuntu.com/ubuntu disco main universe restricted multiverse
deb http://archive.ubuntu.com/ubuntu disco-security main universe restricted multiverse
deb http://archive.ubuntu.com/ubuntu disco-updates main universe restricted multiverse
保存并运行：
sudo apt update
然后尝试：
sudo apt upgrade
更新 2：
您有一些软件包在升级过程中未升级。
首先，删除它，sysstat因为您现在不需要它：
sudo dpkg -r --force-all sysstat
然后用新版本替换软件包：
wget http://mirrors.kernel.org/ubuntu/pool/main/m/mesa/libgl1-mesa-dri_19.0.2-1ubuntu1_amd64.deb
wget http://mirrors.kernel.org/ubuntu/pool/main/n/net-snmp/libsnmp30_5.7.3+dfsg-5ubuntu1_amd64.deb
sudo dpkg -i --force-all libsnmp30_5.7.3+dfsg-5ubuntu1_amd64.deb libgl1-mesa-dri_19.0.2-1ubuntu1_amd64.deb
sudo apt -f install

在 Ubuntu 20.04.1 LTS 上
从官方 Ubuntu 存储库手动下载软件包libsensors5并强制安装：libsensors-config
$ wget http://archive.ubuntu.com/ubuntu/pool/main/l/lm-sensors/libsensors5_3.6.0-2ubuntu1_amd64.deb
$ wget http://archive.ubuntu.com/ubuntu/pool/main/l/lm-sensors/libsensors-config_3.6.0-2ubuntu1_all.deb
$ sudo dpkg -i --force-all libsensors5_3.6.0-2ubuntu1_amd64.deb libsensors-config_3.6.0-2ubuntu1_all.deb
最后一个命令产生以下输出：

The following packages will be upgraded:
libegl-mesa0 libgbm1 libgl1-mesa-dri libglapi-mesa libglx-mesa0 libosmesa6 lm-sensors
7 to upgrade, 0 to newly install, 0 to remove and 1 not to upgrade.
Need to get 12.5 MB of archives.
After this operation, 24.0 MB of additional disk space will be used.
答案3
运行以下命令：
sudo apt remove libsensors-config # remove the package
sudo apt update
sudo apt upgrade
如果需要运行sudo apt autoremove
