OpenShot will not upgrade

I just installed openshot video editor via terminal: this tutorial https://www.ubuntupit.com/install-openshot-video-editor-ubuntu-linux-mint/ on ubuntu 21.04 on a raspberry pi 4b. I tried to start it, but it showed this glitch warning and openshot did not start.

Here's something that N0rbert wanted me to do in terminal (I didn't get that at first) but here it is. At the bottom of this, there is an additional terminal entry NOrbert wanted me to add so I did it too.

I did these entries one after another plus a couple more in one terminal session. THese were suggested in a comment to this question by NOrbert so I did them here. I tried running apt-update and full-upgrade in terminal but it did not upgrade. How would I install the latest installer? How can I fix this?

Solution 1:

The "OpenShot: Stable PPA - Official Releases" PPA does not contain libopenshot libraries for armhf and/or arm64. They support only amd64 (for Intel/AMD computers, not Raspberry Pi).
I have wrote a request about building packages for Raspberry Pi.

Currently you have to remove OpenShot PPA with commands below:

sudo apt-get update
sudo apt-get install ppa-purge
sudo ppa-purge ppa:openshot.developers/ppa

and then you will have older but fully-functional OpenShot from official repository.

Solution 2:

You can download an appimage from the openshot website here: https://www.openshot.org/en/download/

Since it's an appimage, no installation is required. As of this writing, the version offered is 2.6.1

From this page, you can download the single file OpenShot-v2.6.1-x86_64.Appimage. Once downloaded, it needs to be marked as executable, either by setting the properties in your file manager of choice, or by chmod +x OpenShot-v2.6.1-x86_64.Appimage in a terminal.

Then you run it by double-clicking it in the file manager, or typing ./OpenShot-v2.6.1-x86_64.Appimage in the terminal.

Final edit: according to the OP, the appimage did not work on his computer, although it did work on mine.
