我试图删除我的 Ubuntu 16.04 上所有已安装的 python。就目前而言,我现在明白我不应该那样做。但是,仅仅尝试重新安装 python 是行不通的。
当我尝试
$ sudo apt install -f --reinstall python3

我尝试安装一些依赖项,但我发现没有安装成功
$ sudo apt-get -f 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-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).
尝试过不同的方法,但此时我不知道如何解决这个问题
$ sudo apt-get -f install dh-python

dh-python is already the newest version (2.20151103ubuntu1.1).
You might want to run 'apt-get -f install' to correct these:

最佳答案
在 ubuntu 从 16 升级到 18 后,我遇到了与 python3 类似的问题。但是你可以尝试在 16 上使用我的解决方案。只需使用 apt-get
来对抗 apt
注意:我的系统需要安装python2.7。
我遵循了这些步骤:
卸载所有 python3 包:
sudo apt remove python3 && sudo apt autoremove
但这对我没有帮助。因此将尝试定义哪些包仍然存在于系统中:
apt list --installed | grep python*
//possible output: WARNING: apt does not have a stable CLI interface. Use with caution in scripts. libpython-stdlib/bionic,now 2.7.15~rc1-1 amd64 [installed,automatic] libpython2.7-minimal/bionic-updates,bionic-security,now 2.7.17-1~18.04ubuntu1.2 amd64 [installed,automatic] libpython2.7-stdlib/bionic-updates,bionic-security,now 2.7.17-1~18.04ubuntu1.2 amd64 [installed,automatic] libpython3-stdlib/bionic-updates,now 3.6.7-1~18.04 amd64 [installed] libpython3.5/now 3.5.2-2ubuntu0~16.04.12 amd64 [installed,local] libpython3.5-minimal/now 3.5.2-2ubuntu0~16.04.12 amd64 [installed,local] libpython3.5-stdlib/now 3.5.2-2ubuntu0~16.04.12 amd64 [installed,local] libpython3.6/bionic-updates,bionic-security,now 3.6.9-1~18.04ubuntu1.3 amd64 [installed,automatic] libpython3.6-minimal/bionic-updates,bionic-security,now 3.6.9-1~18.04ubuntu1.3 amd64 [installed,automatic] libpython3.6-stdlib/bionic-updates,bionic-security,now 3.6.9-1~18.04ubuntu1.3 amd64 [installed,automatic] python/bionic,now 2.7.15~rc1-1 amd64 [installed] python-apt-common/bionic-updates,bionic-updates,bionic-security,bionic-security,now 1.6.5ubuntu0.5 all [installed] python-minimal/bionic,now 2.7.15~rc1-1 amd64 [installed,automatic] python2.7/bionic-updates,bionic-security,now 2.7.17-1~18.04ubuntu1.2 amd64 [installed,automatic] python2.7-minimal/bionic-updates,bionic-security,now 2.7.17-1~18.04ubuntu1.2 amd64 [installed,automatic]
我们可以看到,系统中有一些python3包。将删除它们。
sudo apt remove libpython3-stdlib libpython3.5 libpython3.5-minimal libpython3.5-stdlib libpython3.6 libpython3.6-minimal libpython3.6-stdlib
现在,尝试安装python3
sudo apt install python3
一切正常
