I need to uninstall another package before current package being installed, I tried put dpkg --remove com.foo.foo.another in preinst file, which doesn't work, it throws error dpkg: error: dpkg status database is locked by another process. How can I achieve that? Appreciate!
You can't do that. Dpkg locks its database for the whole process of installation - none of your scripts will be able to do anything like installing or uninstalling a package.
I had a similar problem. I wanted to install debian package manually during installation of my app. My app had a daemon which I launched as part of installation. To solve my problem in the daemon I waited until dpkg releases the lock and then installed the package. It's very important that I did it in a daemon as it's detached from postinst script, so dpkg can happily finish the installation.
You probably need to do something similar.

I was trying to install Ursina but I was having trouble getting all the required packages I needed to run my code properly. Come to find out, there's a package that refuses to install called 'psd-tools3' that won't install, no matter what I do.
I've been using cmd commands like 'pip install psd-tools3' and 'pip3 install psd-tools3' but no other commands work (i.e. 'sudo pip install psd-tools3' doesn't work because my PC doesn't know what 'sudo' means and doesn't run). I've tried installing required packages for this package, but nothing works. It just keeps giving me this error:
enter image description here
I would really appreciate the help with this problem. All I can really assume is that the Python file '_version' hasn't been created and that's what's throwing the whole program off. If there is a way to add this manually and then install it, I would appreciate steps to do that as well.
I was running this on a Lenovo Thinkpad (Windows 10) on Python 3.10 (I also have Python 3.8.3 but that was installed with the 3.10) and I made sure all packages and pip are up-to-date. Still having this problem and I don't know why.
Seems to me like the issue is on the side of the maintainers of psd-tools3.
For example, looking at the content of the latest source distribution on PyPI, we can see that it does not contain any _version.py file.
This needs to be solved by the project's maintainers, but they do not have a ticket tracker. On the other hand there seems to be an "Author" email address on the project's PyPI page as well as in the project's setup.py script.
A solution might be to clone the project's source code repository (with git), and try to install from the local clone.
Just simply try
pip install psd-tools3==1.9.0
Or
pip install psd-tools3==1.8.2
This should work on your pc as well. I was having same issue, and then I tried this It worked for me
Is there any way, within the chocolateyinstall.ps1 file, to check if the process was triggered with the Upgrade command versus the Install command?
I tried using things like "choco list --lo" and "choco outdated", but those kept bringing up the package currently being installed - even if it hadn't yet been fully installed. I was hoping there was some sort of environment variable or something easy that I've overlooked.
Thanks!
I'm having trouble setting up 2 factor authentication in Ubuntu Server 18.04.
I'm following this tutorial: http://www.ubuntuboss.com/how-to-set-up-2-factor-authentication-in-ubuntu-server-18-04/
But on the first step when I try to install the package I get the package not found error as seen in the title.
sudo apt-get install libpam-google-authenticator
I have looked around to see if the package has been updated and goes by a different name and I am sure I have the most recent version of the package manager.
Has the package changed or is there anyway around this problem.
Had the same problem. Turned out it's because Ubuntu Server doesn't include the Universe Repository.
Add this line
sudo add-apt-repository universe
Then run the command again and it will install.
I found a way round this issue,
/tmp$ wget http://launchpadlibrarian.net/326531917/libpam-google-authenticator_20170702-1_amd64.deb
I was able to manually install it via this link and installed the missing dependencies the same way and was able to finish the tutorial as normal.
I am trying to install create a simple .deb dpkg package.
I have seen multiple packages where, during installation, they output custom messages like Reboot after installation! or Clearing caches or (in the case of iOS) Thanks to [developer]!.
I can't seem to find any way to replicate this myself during installation of my package.
How do I output a custom message to the terminal while dpkg is installing my package?
You can do this by providing a postinst script to the package.
See section 7.6 What is a Debian preinst, postinst, prerm, and postrm script?
Background
I'm working on an academic project to (basically) analyze some "who follows whom" graphs and wanted to get some real data (by building some small datasets) from Twitter using one of the Python Twitter API packages in order to test some ideas I have.
I was a bit careless and installed two packages:
a) python-twitter0.8.2 (http://pypi.python.org/pypi/python-twitter/0.8.2)
b) twitter1.9.1 (http://pypi.python.org/pypi/twitter/1.9.1)
(a) is called python-twitter in pypi, and (b) is called twitter, so that's how I'll refer to them.
Both of these are called by import twitter in the Python interpreter, but when I write that line, I always get the twitter one (if I can figure out how to use the python-twitter one, I'll be able to proceed, but will still have the same underlying problem).
Problem
Since I don't need the twitter package, I decided to uninstall it with pip:
$ sudo pip uninstall twitter
which gives the output:
Uninstalling twitter:
Proceed (y/n)? y
Successfully uninstalled twitter
(actually, I tried the same thing with python-twitter and got a similar response).
However, when running pip freeze, both of these packages show up on the installed list! In fact, I can still use the import twitter command successfully in the interpreter. Clearly the packages have not been uninstalled. What I would love to know is how to uninstall them!
Other Info
I'm using Python 2.7 and Ubuntu 12.04
When running IDLE instead of the shell interpreter, and I type help('modules'), neither twitter nor python-twitter shows up in the list. When typing help('modules') into the shell interpreter, I get a segmentation fault error, and the interpreter crashes. Here's the error:
>>> help('modules')
Please wait a moment while I gather a list of all available modules...

Why other questions have not resolved this for me:
I looked at the similar post at pip freeze lists uninstalled packages and am not having the same issues.
$ sudo which pip
/usr/bin/pip
$ which pip
/usr/bin/pip
which is the same output. In addition, $ sudo pip freeze gives the same output as $ pip freeze.
Any help is very much appreciated!
You can always manually delete the packages; you can run:
sudo rm -rf /usr/local/lib/python2.7/dist-packages/twitter
to remove that package from your dist-packages directory. You may have to edit the easy-install.pth file in the same directory and remove the twitter entry from it.
While Martin's solution works, as a work around, it does not provide a direct answer.
Ubuntu's pip version for your Ubuntu version (12.04) is:
python-pip (1.0-1build1)
This is also the same version for Debian Wheezy. This version has a weired bug, which causes packages not to be removed.
If you obtain pip from upstream using the script get-pip.py you will have a fixed version of pip which can remove pacakges (as of now v. 1.5.6).
update
Python's pip is really a fast moving target. So using Debian's or Ubuntu's pip is guaranteed to have bugs. Please don't use those distribution's pip.
Instead install pip from upstream.
If you would like to register pip installed packages as system packages I really recommend that you also use stdeb.
I was facing difficulty while upgrading a package because pip was not able to uninstall it successfully. I had to delete the .egg-info and the folder as well in /usr/lib/python2.7/dist-packages and then I tried to install with --upgrade and it worked.
For me, it was due to the fact that I was running pip freeze, which gave me different results than sudo pip freeze.
Since I was uninstalling using sudo, it was not uninstalling it in the "non-sudo" session. Uninstalling without sudo fixed that.
In my case (moving pyusb 0.4x to 1.0x), removing the old package with apt-get remove python-usb and manually installing the manually downloaded package via python setup.py worked. Not pretty, but working.
