Sudo apt-get安装（更新，升级等）已停止在我的系统上工作。我遵循了在线上的建议线程，似乎使情况变得更糟！
目前， sudo apt-get upgrade
返回消息：
dpkg: error processing package software-properties-common (--configure):
package is in a very bad inconsistent state; you should
reinstall it before attempting configuration
Errors were encountered while processing:
software-properties-common
E: Sub-process /usr/bin/dpkg returned an error code (1)
尽管
sudo apt-get install --reinstall software-properties-common
返回消息：
/var/lib/dpkg/info/software-properties-common.prerm: 6: /var/lib/dpkg/info/software-properties-common.prerm: py3clean: not found
dpkg: warning: old software-properties-common package pre-removal script subprocess returned error exit status 127
dpkg: trying script from the new package instead ...
/var/lib/dpkg/tmp.ci/prerm: 6: /var/lib/dpkg/tmp.ci/prerm: py3clean: not found
dpkg: error processing archive /var/cache/apt/archives/software-properties-common_0.97.11_all.deb (--unpack):
new software-properties-common package pre-removal script subprocess returned error exit status 127
有任何想法吗？
@Raffa：
sudo apt-get install --reinstall pythin3-minimal
返回以下错误：
dpkg: error processing package python3 (--configure):
package is in a very bad inconsistent state; you should
reinstall it before attempting configuration
dpkg: dependency problems prevent configuration of software-properties-common:
software-properties-common depends on python3:any; however:

新鲜玩意： sudo dpkg --configure -a && sudo apt update --fix-missing && sudo apt install -f && sudo apt full-upgrade
告诉我： Package python3 is not configured yet.
跟随从@Raffa（感谢Raffa！）获得的线索，我在完成以下操作后设法使事情正常进行：
首先，手动重新安装Python：
apt-get download python3 python3.7 python3.7-minimal libpython3.7-minimal
sudo dpkg -i *python3*.deb
sudo apt install -f
然后手动重新安装software-properties-common：
apt-get download software-properties-common
sudo dpkg -i *software-properties-common*.deb
sudo apt install -f
我认为那只是将我的系统重置为开始时的状态。我从Reddit线程获得了修复程序：https : //www.reddit.com/r/pop_os/comments/aduzbg/upgrading_1804_to_1810_python3_install_is/
apt-get remove --purge python2.7-minimal
sudo apt-get autoremove
之后，事情又恢复了！
