On Ubuntu 18.04 if using the PPA, you can install python3-openshot to resolve this:

sudo apt-get install python3-openshot

You have opened other issue: https://github.com/OpenShot/openshot-qt/issues/3219

At startup OpenShot cannot check that the required library (_libopenshot_) is out of date and thus fails to start.

I hope you know how to get most recent _libopenshot_ for your system.

ok, but I installed with apt from a ppa... shouldn't it have the correct dependencies?

I have the same problem with OPENSHOT_VERSION_FULL. How is openshot checking the updated version. Does it need to be online for it to check? Can it function in an offline mode?

muziker on 14 Feb 2020

In site-packages/_openshot.so, there is the string OPENSHOT_VERSION_FULL, but when doing this

import openshot
print(openshot.OPENSHOT_VERSION_FULL )

gives an error because openshot.OPENSHOT_VERSION_FULL isn't there

muziker on 14 Feb 2020

I'm not common with the PPA packaging and how it checks for required version of _libopenshot_.

On Windows there is "frozen" version of Python with OpenShot scripts and all required libs (including libopenshot). You just downloading installation file and performing install (or unpack).

SuslikV on 14 Feb 2020

Instead of me adding a new issue, i'll chime in on this thread instead.

I'm trying to run openshot, by using the python3 src/launch.py. The pythonpath is pointing to the [path to libopenshot folder]. The reason the start fails is it looks for the OPENSHOT_VERSION_FULL string definition that is set by libopenshot when swigging the files to a python module. The sofile _openshot.so contains symbols that point to OPENSHOT_VERSION_FULL, but the python module does not return anything when calling _openshot.OPENSHOT_VERSION_FULL.

I checked by loading the openshot python module and querying for this string. All the libraries, are from the git repo.

muziker on 15 Feb 2020

@muziker if you are using _master_ branch, here is the definition:

https://github.com/OpenShot/libopenshot/blob/fe8ea216f4d006f1f0c57fc36203ebbfc65d276f/include/OpenShotVersion.h.in#L35

SuslikV on 15 Feb 2020

Right, the definition is there, but for the openshot python module to be able to reference it, the interface is swigged to allow _openshot.py to access this definition. For some reason, _openshot.py does not have that, so _openshot.OPENSHOT_VERSION_FULL returns nothing, hence, at least in my case, running the launcher fails

_libopenshot_ installation is not just a library file. You make look at the corresponding cmake script.

Edit:
On Windows, the libopenshot install tree may look like this:

Solved it for me. ~~Can anybody here improve the text on https://www.openshot.org/ppa/ or ping somebody who can?~~ Sorry that I don't; I am horribly short of time atm.
This should be resolvable by setting the package dependency and version constraint in the ppa package. Probably file a bug on https://launchpad.net/~openshot.developers/+archive/ubuntu/ppa ?

Probably file a bug on https://launchpad.net/~openshot.developers/+archive/ubuntu/ppa ?

I didnt manage to file a bug on launchpad, but wrote a mail to the mailinglist (which I am not subscribed to, no idea if it gets through)

fwolfst on 2 Apr 2020

Just ran into this myself. https://github.com/OpenShot/openshot-qt/issues/3220#issuecomment-607603781 fixed it. Spent the last 5 or 10 minutes looking for a place to submit a bug on launchpad, and couldn't find one.

I'd suggest renaming the issue to "Stable PPA package for Ubuntu 18.04 is missing python3-openshot dependency." Hopefully one of the package maintainers will see it.

Also fixed it for me. Thanks by the way.

The suggested solution (sudo apt-get install python3-openshot) did not work for me.

I solved it by:

dpkg -l | grep openshot
ii  libopenshot-audio6:amd64              0.1.8+dfsg2+67+201903210434~ubuntu14.04.1   amd64        library for high-quality audio editing
ri  libopenshot16:amd64                   0.2.2+dfsg1-1+b1                            amd64        library for high-quality video editing
ii  openshot-qt                           2.5.1+dfsg2+1218+202003032149~ubuntu19.04.1 all          OpenShot video editor
ii  python3-openshot                      0.2.2+dfsg1-1+b1                            amd64        OpenShot video library bindings for Python 3
sudo apt-get remove libopenshot-audio6 openshot-qt python3-openshot
sudo apt-get install openshot-qt

So: Listing all openshot packages, removing them, reinstalling openshot-qt.

Looks like this has been solved, closing this.

ctsdownloads on 14 May 2020

@ctsdownloads Could you edit the two solutions (manual install of python3-openshot and longer one with deinstall then reinstall) into the initial post? This thread is quite prominent on my searchengine and experience says people don't read till the end :)

angelo-fuchs on 15 May 2020

had the same issue. It would be nice to add the installation python3-openshot in the instructions here : https://www.openshot.org/ppa/
hope that helps ;)
