It seems that following the official MongoDB installation instructions when installing on Debian direct you to a world of pain.

First, it did not install correctly, so now I am trying to remove all installed MongoDB packages to be able to start from scratch.
But frustratingly, because it (presumably) did not install cleanly, it won't uninstall.

Originally, I installed it using these instructions.

Currently, I've managed to remove every package apart from mongodb-org-server which, just won't go.

An attempted removal results in the following:

$ sudo apt-get remove mongodb-org-server
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages will be REMOVED:
0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded.
1 not fully installed or removed.
After this operation, 23.9 MB disk space will be freed.
Do you want to continue [Y/n]? y
(Reading database ... 31030 files and directories currently installed.)
Removing mongodb-org-server ...
invoke-rc.d: unknown initscript, /etc/init.d/mongod not found.
dpkg: error processing mongodb-org-server (--remove):
 subprocess installed pre-removal script returned error exit status 100
invoke-rc.d: unknown initscript, /etc/init.d/mongod not found.
dpkg: error while cleaning up:
 subprocess installed post-installation script returned error exit status 100
Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)

Any idea how I can properly and cleanly get rid of MongoDB now?



apt-get --reinstall install mongodb

This will pretend that mongodb isn't installed already and overwrite the old files.

Afterwards you should be able to remove it like usual.


Just follow these commands to uninstall mongodb

sudo apt-get purge mongodb mongodb-clients mongodb-server mongodb-dev

sudo apt-get purge mongodb-10gen

sudo apt-get autoremove

    This generates the same error as reported by the OP. – mightypile Dec 23 '15 at 15:42

Uninstall and remove Mongo packages.

$ sudo apt-get purge mongodb-org*

Check if related directories removed

$ sudo rm -r /var/log/mongodb
$ sudo rm -r /var/lib/mongodb

Recheck for autoremove any remaining mongo packages

$ sudo apt-get autoremove

Configure your directory

$ sudo dpkg --configure -a

Force install anything required

$ sudo apt-get install -f

Re-install from https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/

Finally restart your Ubuntu and check status of Mogodb server as you did earlier.
