problems installing mnemosyne 2.6 on kubuntu 17.10

[olese...@gmail.com]

I am having some troubles installing / running mnemosyne 2.6 on my kubuntu 17.10

Problem 1: I can't run mnemosyne as regular user.
Problem 2: I can't set up mnemosyne (when running as root) to enable sync with my mobile running mnemosyne for android.

I have given details of my installation along with error output from mnemosyne below.

I hope someone can guide me along to fixing my installation.

lsb_release -a:
o LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 17.10
Release: 17.10
Codename: artful


lars@lars-Studio-1749:~/programs/Mnemosyne-2.6$ uname -a
Linux lars-Studio-1749 4.13.0-32-generic #35-Ubuntu SMP Thu Jan 25 09:13:46 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

I am using python 3.6:

Initially I had installed mnemosyne using apt-get, but then I got mnemosyne 2.4
And syncing with mnemosyne from my android mnemosyne app gave an error, that
I needed the same version of the database on each device.
So I tried installing mnemosyne 2.6:

ars@lars-Studio-1749:~/programs/Mnemosyne-2.6$ which python
/usr/bin/python
lars@lars-Studio-1749:~/programs/Mnemosyne-2.6$ ls -lahtr /usr/bin/python
lrwxrwxrwx 1 root root 16 Feb 3 14:10 /usr/bin/python -> /usr/bin/python3
lars@lars-Studio-1749:~/programs/Mnemosyne-2.6$ ls -lahtr /usr/bin/python3
lrwxrwxrwx 1 root root 9 Jan 11 17:12 /usr/bin/python3 -> python3.6

I initially could not run "sudo python setup.py install"
because I did not have python3-setuptools installed, so I installed that and tried again:
sudo apt install python3-setuptools
sudo python setup.py install

This time the installation went well, but then when I started mnemosyne

I got the following error:

An unexpected error has occurred.
Please forward the following info to the developers:

Then I tried running mnemosyne as root from the console:

sudo mnemosyne

This time mnemosyne started successfully, everything seemed fine untill I configured the server so I could sync with my android phone.

then I got the error below:

Hi,

As the error message suggests, you need to install the cheroot package first.

Cheers,

Peter

Thanks Peter Bienstman. that was a little embarassing, i should have read the error output myself.

I use very few python tools which I install myself, so it took me a while to
. get it installed.

For the benefit of others who like me face this problem and have very little python know how, here is what I did:

Install pip:
sudo apt install python3-pip

Use pip to install cheroot:
python3 -m pip install cheroot

Now, I can start mnemosyne as normal user, and the initial sync with my android mnemosyne app was successfull.
