I just finished installing python 3.5.1 on my Ubuntu, but am faced with this error message, regardless if I'm installing with Anaconda or with apt-get:

No module named 'gdbm'

that normally displays on my terminal. I have also tried installing gdbm using:

sudo apt-get install gdbm

but doesn't solve the problem. Can I get a help on how to fix this problem from anyone here?

In my case, if I tried running any command that doesn't exist in a bash shell I would get this gross error:

$ programthatdoesntexist

Traceback (most recent call last):

  File "/usr/lib/python3.5/dbm/gnu.py", line 4, in <module>

    from _gdbm import *

ImportError: No module named '_gdbm'



During handling of the above exception, another exception occurred:

    raise ImportError(str(msg) + ', please install the python3-gdbm package')

None of the answers above worked in my case. Although this problem has been solved, this might help someone. If you are still having this issue, maybe this will help:

I had installed python3.6 from the repository ppa.launchpad.net/jonathonf/python-3.6/ubuntu , and apparently that broke some things.

When tying to reinstall the packages command-not-found python3-commandnotfound python3-gdbm python3-gdbm-dbg sessioninstaller, I noticed that apt was pulling sources from here:

Get:1 http://ppa.launchpad.net/jonathonf/python-3.6/ubuntu xenial/main amd64 python3-gdbm amd64 3.6.5-3~16.04.york0.2 [14.6 kB]

To fix the issue, I simply removed that repository:

sed -i ' s/^/#/' /etc/apt/sources.list.d/jonathonf-ubuntu-python-3_6-xenial.list

And than re-ran this command (as root):

apt update ; apt purge python3-gdbm ; apt install command-not-found python3-commandnotfound python3-gdbm python3-gdbm-dbg sessioninstaller

Now, everything works again:

$ lol

No command 'lol' found, did you mean:

 Command 'sol' from package 'aisleriot' (main)

 Command 'col' from package 'bsdmainutils' (main)

lol: command not found

sudo apt-get install python3.5-gdbm

helped me

Have you tried installing the package python3-gdbm

sudo apt-get install python3-gdbm

I have python 3.6 install and working i have tried many things but

sudo apt-get install python3.6-gdbm

This command worked for me

I had the same issue and got it solved by:

sudo apt install python3-gdbm=3.5.1-1

dpkg -L python3-gdbm

running synaptic, for something else, displayed that python3-gdbm needed an update. I allowed synaptic to make the update and:
Now I get the same issue back.

When running above commands again I get as message, in the terminal, for the first command: The following packages will be DOWNGRADED : python3-gdbm.
After answering Y to the question if I want to continue, traceback works again.

So there is clearly something wrong (bug) in the latest version of python3-gdbm.

sudo apt install python3-django

helped me
