Errors of python-catkin-pkg & python-rospkg-module [closed]
so, i uninstalled ROS manually about a week ago (the proper way would have been something like sudo apt-purge ros*) ..
and it has messed up my Ubuntu OS. now, whenever I try to update through the software update , i get the below error:

basically the main error is: Errors were encountered while processing: /var/cache/apt/archives/python-catkin-pkg-modules_0.3.7-1_all.deb /var/cache/apt/archives/python-rospkg-modules_1.1.3-1_all.deb E: Sub-process /usr/bin/dpkg returned an error code (1)
i have tried deleting the files, installed ROS again .. all without success. :(
Please explain what you mean by "uninstalled ROS manually". Also this isn't really a ROS problem but an apt/corrupted dpkg problem you're probably better off looking on other forums with apt/dpkg experts.
@thfoote i deleted the folders which is relevant to ROS in my drive. Hmm, i ve attempted the software updater application and package manager application and it is not able to solve the problem. also, i uninstalled python and reisntalled it but the problem remains python-rospkg and python-catkin
You appear to have removed too many things including pycompile and pyclean which are core dependencies required to unpack the debian packages. They are found in
python-minimalpackage. You are likely going to want to reinstall any debian package for which you have touched.There will be more experts for your corrupted dpkg/apt issues on Ubuntu and Debian forums such as: https://askubuntu.com/questions/79000... which I found quickly with related searches.
If you can't find your solution by browsing I'd suggest you ask your question there. When you do the more details about what you did the easier people will be able to help you.
the link u shared was not able to solve my problem. but yea i will ask in the ubuntu forums. thx!
