Mike, OK I see what went wrong. Here is an easy to follow set BUT honestly from my point of view, just using the static tar is easier for experimentation, for backout, and to keep multiple versions instead of installing the package as a system package. The instructions you followed were for Ubuntu 14 at the beginning of the instructions. (Add "sudo" for the necessary commands below. The first step is correct that you already did and only have to do once: apt install software-properties-common apt-transport-https Then read down in the instructions to not use version 14: For Ubuntu 20.04 (Focal Fossa), run the third set of lines below: -- which in this case is: apt-add-repository https://cinelerra-gg.org/download/pkgs/ub20 Next edit the file* /etc/apt/sources.list* to make sure the added line contains [trusted=yes] as shown below: deb [trusted=yes] https://cinelerra-gg.org/download/pkgs/ub20 focal main Finally you run these: apt update apt install cin BTW: there is now a Cinelerra YouTube channel with many expert examples of usage accessible from the website under Support: https://www.youtube.com/channel/UCW97mOMN_tAqVCn8k4Euf1w/ BUT if you just want to make a quick video to see how to operate Cinelerra, you can follow the Quickstart.pdf file at: https://cinelerra-gg.org/download/CinelerraGG_Quickstart.pdf (needs to be updated too) On Tue, Jun 23, 2020 at 11:59 AM Mike Squires < [email protected]> wrote:

I followed the instructions, as I understood them, and had an error.

I first executed

sudo apt install software-properties-common apt-transport-https sudo apt update

Then:

Done E: The repository 'https://cinelerra-gg.org/download/pkgs/ub20 focal Release' does not have a Release file. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details.

I've been able to compile by downloading source and then compiling locally, but had to rebuild the system in order to solve a problem with printing.

I'm still at the experimenting stage, so this is not a major problem.

Mike
