我尝试更新 Python,但我不知道版本隔离,而是删除版本,因此,我删除了 Ubuntu 16.04 VPS 中的所有 Python 版本。现在我无法通过 apt-get 安装任何东西。

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
dh-python : Depends: python3:any (>= 3.3.2-2~)
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
我尝试手动安装以将 Python 2.7 导入到/usr/lib 并且现在可以使用,但现在的问题是这种依赖关系:“dh-python”。# apt-get install python3.5-minimal

python3.5-minimal is already the newest version (3.5.2-2ubuntu0~16.04.5).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
python3.5-minimal : Depends: libpython3.5-minimal (= 3.5.2-2ubuntu0~16.04.5) but it is not installable
Recommends: python3.5 but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
我已经尝试了所有列出的方法,但无法修复依赖关系。在尝试修复之前,问题是 Python2.7 而不是 python3,现在手动安装 python3 并没有解决问题。
最佳答案
经过更多研究,我创建了一个与 Debian 相关的帖子。处理 Ubuntu 16.04 的一些修改,尝试了本指南,现在一切正常:
步骤1。
cd /tmp
apt-get download libpython3.5-minimal
apt-get download python3.5-minimal
apt-get download python3-minimal
apt-get download libpython3.5-stdlib
apt-get download python3.5
第2步。rm -rf /usr/local/lib/python3.5*
rm -rf /usr/local/bin/python3.5*
update-alternatives --remove python3 /usr/local/bin/python3.5
hash -r # removes cached python3 binary path
步骤 3。cd /tmp
dpkg-deb -x libpython3.5-minimal_3.5.2-2ubuntu0~16.04.13_amd64.deb missing
dpkg-deb -x libpython3.5-stdlib_3.5.2-2ubuntu0~16.04.13_amd64.deb missing
dpkg-deb -x python3.5-minimal_3.5.2-2ubuntu0~16.04.13_amd64.deb missing
dpkg-deb -x python3.5_3.5.2-2ubuntu0~16.04.13_amd64.deb missing
dpkg-deb -x python3-minimal_3.5.1-3_amd64.deb missing
第4步。cd /tmp/missing
ls -lR /tmp/missing # if you are curious about overwriting your HD
sudo cp -rpfv /tmp/missing/* /
步骤 5。python3
Python 3.7.3 (default, Apr 3 2019, 05:39:12)
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
导入并测试新版本:>>> import sys
>>> print(sys.version_info)
sys.version_info(major=3, minor=7, micro=3, releaselevel='final', serial=0)
>>>
>>> quit()
步骤 6。rm -rf /tmp/missing
步骤 7。dpkg -s -a python3.5 | grep reinstreq
# Any listing also needs to be reinstalled along with python3
apt-get install --reinstall python3
步骤 8。apt-get autoclean
apt-get autoremove
# (see the packages that will autoremove, you need to reinstall it again after: apt-get install --fix-broken --reinstall <<packages>>)
步骤 9。尝试安装通用 Prop 。
sudo apt install software-properties-common
如果它工作,现在安装完成。我已经在 Ubuntu 16.04 上尝试过这个,安装了 Python2.7,但没有安装 Python3 或 Python3.5。我最初安装的是 Python3.5,这就是为什么尝试安装该版本而不是最新版本的原因。
