Всунутый цикл, потому что 'склонный - поврежденная фиксацией установка' не помогает при установке ROS, Мелодичного на Ubuntu 18.04 LTS

Эта проблема может быть связана с ROS полностью, однако, в настоящее время, я не уверен в источнике ошибки. Следовательно я отправляю его в этом многочисленном сообществе.

Я пытаюсь установить ROS, Мелодичный на Ubuntu 18.04.2 LTS ПК. К сожалению, команда sudo apt install ros-melodic-desktop-full неудавшийся. Ниже вывод той же команды, при выполнении снова:

ravi@lab:~$ sudo apt install ros-melodic-desktop-full
Reading package lists... Done
Building dependency tree       
Reading state information... Done
ros-melodic-desktop-full is already the newest version (1.4.1-0bionic.20190204.220757).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 python-rosdistro-modules : Depends: python-rospkg-modules but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

Это предлагает работать apt --fix-broken install который я сделал, но это не решает проблему. Посмотрите ниже:

У меня нет подсказки теперь о фиксации его. Ниже больше информации о ПК:

ravi@lab:~$ python --version
Python 2.7.15rc1

ravi@lab:~$ uname -a

Какое-либо обходное решение?

Я столкнулся с этой той же проблемой и записал сценарий для удаления пакетов установки ROS. Я должен был выполнить его многократно как это, пока не было никакого вывода.

Вот сценарий

import os
import sys
import re

data = sys.stdin.read()
lines = data.split('\n')

pkgPat = " [a-zA-Z0-9\-]* : Depends: .*"
pkgNamePat = " [a-zA-Z0-9\-]* :"

relLines = []
for line in lines:
    if(re.match(pkgPat, line) is not None):
        relLines.append(line)

for line in relLines:
    pkg = re.search(pkgNamePat, line)[0][1:-2]
    if pkg is not None:
        os.system('sudo dpkg -r --force-all ' + pkg)
    else:
        print("None: " + line)

Выполните его многократно, пока нет никакого вывода с (сценарий называют fixros.py:

sudo apt-get autoremove | fixros.py

sudo dpkg -r --force-all python-rospkg

После этого sudo apt --fix-broken install Если вы хотите переустановить ros, запустите sudo apt-get remove ros-*, чтобы удалить ros. Затем установите ROS из https://wiki.ros.org/ROS/Installation

Просто сделай :

sudo dpkg -P --force-all PACKAGETOREMOVE
sudo apt --fix-broken install
sudo apt-get clean
sudo apt-get autoremove
