Ubuntu：18.04
当我尝试 sudo apt-get upgrade这样做时出现了这个错误：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Calculating upgrade... Done
The following packages were automatically installed and are no longer required:
libpython3.7-minimal libpython3.7-stdlib
Use 'sudo apt autoremove' to remove them.
0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.
1 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.

但建议的推荐sudo apt autoremove也显示错误：

The following packages will be REMOVED

因此，看起来 py3compile 存在一些未发现的问题。我尝试了sudo apt-get -f install以下方法，结果如下：

0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.
1 not fully installed or removed.

当我尝试时，会出现同样的 py3compile: not found 错误sudo apt-get install --reinstall python3-minimal
我是 ubuntu 新手，因此我很乐意获得一些帮助。
答案1
这个答案对我有帮助，希望它能解决一些人的问题。
通过以下方式重新配置所有已解压但未配置的软件包：
sudo dpkg --configure -a
如果上述方法无效，请尝试python3-minimal通过以下方式重新安装包：
sudo apt install -f --reinstall python3-minimal
或者，运行：
apt-get download python3-minimal
sudo dpkg -i *python3*.deb
sudo apt install -f
或者从 kernel.org 下载 .deb 文件并通过以下方式从文件安装：
sudo dpkg -i python3-minimal_*.deb
答案2
py3compile not found我在安装 Ubuntu 20.04.1 时遇到了问题python3-pip。我python3-minimal按照答案的建议重新安装，然后再次尝试安装python3-pip，成功了！
sudo apt install -f --reinstall python3-minimal
sudo apt install -f --reinstall python3-pip
希望这对将来的某人有所帮助！
答案3
就我而言，我正在升级 Ubuntu 16。我的解决方案是将默认的 /usr/bin/python 设置回 python2，因为 python3 没有所需的所有依赖项。
rm /usr/bin/python /usr/bin/python3
ln -sf /usr/bin/python2.7 /usr/bin/python
