    Thanks for the script. But I got an error installing Flectra ERP on a fresh Ubuntu 18.04 x64 in a Digital Ocean droplet:

    The command sudo pip3 install -r requirements.txt


    Ignoring lxml: markers 'sys_platform == "win32"' don't match your environment
    Ignoring pypiwin32: markers 'sys_platform == "win32"' don't match your environment

    And, then:

    Building wheels for collected packages: lxml
    Running bdist_wheel for lxml ... -^error
    Failed building wheel for lxml
    Running clean for lxml
    Failed to build lxml

    As the install did not complete, I installed the other packages using:

    pip3 install ebaysdk greenlet gevent html2text MarkupSafe Jinja2 Mako pbr mock num2words \
    oauthlib ofxparse passlib phonenumbers Pillow psutil psycopg2 pyparsing pydot pyldap \
    pyserial python-dateutil pyusb qrcode reportlab suds-jurko python-stdnum vatnumber vobject \
    Werkzeug XlsxWriter xlwt xlrd linecache2 traceback2 argparse unittest2 numpy

    Also, it is not clear in the instructions that the address must include the port to start Flectra. I did it using:


    This way I could open the database configuration page. But, then, after trying to create the database, I got this error:

    Database creation error: relation "ir_model" does not exist LINE 1: SELECT * FROM ir_model WHERE state='manual' ^

  • Hello, I am new to Flectra. I like it alot. I did the installation of flectra 1.5 on digitalocean successfully. There was no error message during installation.

    However I cannot print to pdf and got notification "Unable to find Wkhtmltopdf on this system. The report will be shown in html." I tried to install wkhtmltopdf again with script: "wget && sudo gdebi -n wkhtmltox- && rm wkhtmltox- sudo ln -s /usr/local/bin/wkhtmltopdf /usr/bin/ && sudo ln -s /usr/local/bin/wkhtmltoimage /usr/bin/"

    and received message the file exisits already:

    Reading package lists... Done Building dependency tree
    Reading state information... Done Reading state information... Done This package is uninstallable Dependency is not satisfiable: libpng12-0

    root@flectra:~# sudo ln -s /usr/local/bin/wkhtmltopdf /usr/bin/ && sudo ln -s /usr/local/bin/wkhtmltoimage /usr/bin/ ln: failed to create symbolic link '/usr/bin/wkhtmltopdf': File exists

    What did I do wrong and how can I solve this issue?

    Thanks for any advice!

  • Hey

    Seams wkhtmltopdf s already installed.

    What output you have, if you run command: wkhtmltopdf -V

    Then, how you access to your flectra instance? . Over IP . a named URL like

    Check als /etc/hosts file, that your calling URL is existing there and also check the system parameter "web.base.url":

    settings > activate developer mode


    settings > technical > parameters > system parameters



  • Hello, the installation is done in the / etc and in / opt is where the addons are. to access from a URL you can use the port you have in the config.

  • Hey Thomi,

    I am impressed by your quick response!

    I ran the the command: wkhtmltopdf -V and got: root@flectra:~# wkhtmltopdf -V wkhtmltopdf (with patched qt)

    I access my flactra through IP. I checked the system parameter"web.base.url" and my IP address is there. Is a domain assigned to IP mandatory?

    Thanks & regards Michael

  • Hello, good if you already have your domain you can use a subdomain or alias, which points to the IP of your fleztra.

    In this way it is easier to access the system and not writing the IP. Only putting the subdomain and the port.

    I followed the above mentioned steps to install flectra on my Ubuntu 18.04 but I am encountering some errors at the point of installing geoliteCity databases. By using this command:

    wget -N && sudo gunzip GeoLite2-City.tar.gz && sudo mkdir /usr/share/GeoIP/ && sudo mv GeoLiteCity.dat /usr/share/GeoIP/

    I am not successful as I get the following error:

    mv: cannot stat 'GeoLiteCity.dat': No such file or directory

    I tried to skip this step and Flectra installs and starts well but I am not able to view any data. The menus load well, but instead of views and data from databases, I get a blank view page. Screenshot_from_2019-04-01_19-47-52 Could this be the problem? And how can I solve the above error?

    Edited by Japheth Mutai
  • Hello, you can solve the problem by downloading the data file from another source. wget

    In the installation you can try before executing the apt-get update, so that you update the directories. The error of the blank window is not by the geoip.


  • Japheth Mutai @japhemchirie ·

    Hi Miguel, thanks for your prompt response.

    What will be the other following commands be like? Example: sudo gunzip GeoLite2-City.tar.gz && sudo mkdir /usr/share/GeoIP/ && sudo mv GeoLiteCity.dat /usr/share/GeoIP/

    I have tried replacing with the subsequent file name but I am not successful.

  • Richard @carbs.richard ·

    Hello, I managed to run the script with no errors on a VirtualBox with Ubunut 18.04

    I then opened Firefox but I don't know how to get to Flectra.

    What's next?

  • Hello... Flectra's default Port ist 7073, so just navigate to http://localhost:7073 .

    You also can check /etc/flectra/flectra.conf where all the default settings are set.

  • Richard @carbs.richard ·

    Thanks Thomas,

    I did try this http://localhost:7073, so I went and double checked my installation. Then I found that there was an error.

    This line was missing a sudo {{**sudo** git clone --depth=1 --branch=1.0 /opt/flectra/server }}

    I stated another environment in VirtualBox and did the installation again, and "voila" http://localhost:7073 worked.

    Now I just need to figure out how to access flectra from another computer in the network. Is there anyone that could guide me how to do this, or can anyone post a comment, or should I create a new post?

  • access from any other comupter, just open http://IP-OF-YOUR-MACHINE:7073

  • @thomich Is it possible to do it if the installation was on windows? It does not work for me

  • Richard @carbs.richard ·

    Hi Thomas, i tried your suggestion, a few different ways: but no good.

    I have a Virtual Box installed on Windows 10.

    I insllaed Ubuntu 18.04 in a Virtual Box.

    My Network setting as follows: image

    There seems to be an issue on how my network is setup: using ssh I tried to identify my IP

    $ hostname -I

  • The current-state snippet works, provided you sudo line 5. As written, it fails on me (on a fresh Digital Ocean droplet). I ran it line-by-line and adding sudo to line 5 worked even though I did get some occasional minor errors thrown elsewhere in the process.

  • Hi Miguel, Newbie, I was installing flectra by your snippet and ran into an error $1712996 (comment 124549044) The error is:

    sudo pip3 install -r requirements.txt bash: cd: /opt/flectra/server: No such file or directory

    Should i make the directory??

  • Hi Remy, i'm sorry for that error. Please download bash pip3 from other source, I do because coming soon upload update to snipped.


  • Hi, Ive register with in order to download the GeoCity.dat, but the way they provide the file is in GeoLite2-City_20200609.tar.gz and after upzip the extension is .mmdb

    QUESTION, what's the solution for this issue (renaming the file isn't the issue it's the extension???)

    Hello Everyone I have followed the instructions and installed flectra. The service is also running but I am unable to connect to it via my browser. I have installed it on the live server.

  • Nunya Business @nunyabuisness ·

    These instructions need an edit/update. Presumably the script is intended to be run as a local user with administrative (sudo) access, and not as root, hence all the sudo commands all over the script. When run this way however, the git clone fails because the user running the script does not have permission to write into /opt/flectra.

    It looks like all the script needs is another sudo in front of the git clone since it's followed by a chown.

  • Nunya Business @nunyabuisness ·

    Later in the script is another issue. The command wget fails because is not a valid hostname. The files are however available here:

  • Nunya Business @nunyabuisness ·

    The command sudo ln -s /usr/bin/nodejs /usr/bin/node is not needed either, as the link already exists in newer installs of nodejs.

  • @nunyabuisness thanks for input, have made the needed changes..

  • Is there a way to update flectra when this script is used? Thanx in advance.

  • any one have snippets for Ubuntu Focal 20.04 LTS setup procedure
