Hello,

I´m trying to install in 18.04. Is this possible?

Here are the errors I am getting, when following your installation instructions:

(short way) the base requirements can not be met:

xxxxx@xxxxx:/xxxxxx/papermergedms# python3 -m venv .venv --system-site-packages
xxxxx@xxxxx:/xxxxxx/papermergedms# source .venv/bin/activate
(.venv) xxxxx@xxxxx:/xxxxxx/papermergedms# pip3 install -r requirements/base.txt
Collecting mglib==1.2.7 (from -r requirements/base.txt (line 1))
  Could not find a version that satisfies the requirement mglib==1.2.7 (from -r requirements/base.txt (line 1)) (from versions: 1.0.0, 1.0.1)
No matching distribution found for mglib==1.2.7 (from -r requirements/base.txt (line 1))
(.venv) xxxxx@xxxxx:/xxxxxx/papermergedms#

(Detailed Version) Version not matching:

# python3 --version
Python 3.6.9
# pip3 --version
pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6)

Small issue: On 18.04 there is no pdftk. Any ideas?

This may mean that the package is missing, has been obsoleted, or

I am sure that your DMS is exactly what I am looking for my home. I´d love to get it up and running!

Kindest regards and thank you in advance,

Hey Harald,

you can replace pdftk by stapler (pure python) and use a script to translate arguments.
Inhaber done this for Synology package as well.

Hi @mharald, you need to have python >= 3.7

Create python virtual environment using virtualenv and provide python interpreter version as argument

virtualenv .venv -p python3.7

Python error is little bit confusing. mglib==1.2.7 is there available in pypi but it has set python version >= 3.7. Because you use python 3.6 pip tells you, confusingly enough, "no distribution found".

I updated the documentation today :

@ciur commented on GitHub (Sep 2, 2020):

@mharald, regarding pdftk error. It is because in Ubuntu 18.04 method of installing pdftk is little bit different (pdftk package was introduced in ubuntu 19... or 20 I think).

Try to install pdftk using this method for example. Or just google it, I am sure you will find the answer.
Just don't forget to include correct path of pdftk in your papermerge.conf.py configuration file:

$ cat papermerge.conf.py
  
 BINARY_PDFTK = "/snap/bin/pdftk"  # on Ubuntu 20.04;

Use:

$ which pdftk

command to figure out corret path to pdftk binary.
Here are all binary dependencies settings.

Hello,

Thank you for the fast reply.

I tried giving the version as a parameter. Here is the output:

@harald

try to install python3.7 using this method or this one

Disclaimer: I just googled "install python 3.7 on ubuntu 18.04" :))
The command:

$ virtualenv .venv -p <python interpreter>

Will install in virtual environment mentioned version only if that python version is available on your system. You have only 3.6

@mtonnie which stapler application you exactly mean? This one?

@ciur commented on GitHub (Sep 2, 2020): @mtonnie which **stapler** application you exactly mean? [This one](https://pypi.org/project/stapler/)?

@mtonnie which stapler application you exactly mean? This one?

Yes, exactly this one. I'm using this wrapper to convert the arguments from pdftk to stapler.
I have decided to use this solution, because of the following two topics:

(cross) compiling pdftk is a nightmare
License might be difficult in case of redistribution

@mtonnie, hm, license is a very good argument :). I was concerned about pdftk license as well :)
I opened this ticket to keep a reminder for me to replace pdftk with staple (because of license).
