If you want the latest Cinelerra GG on 18.10 you’ll need to trick the system. If you’re not comfortable you can always wait.

First thing is first, add the PPA. This will cause an error, but we will fix that so ignore it. Type each command in the terminal:

sudo apt-add-repository \
https://cinelerra-gg.org/download/pkgs/ub18

Open the sources file:

sudo /etc/apt/sources.list

Find the line that references cinelerra and change it to, all on a single line:
You can just add and replace the highlighted items.

deb [trusted=yes] 
 https://cinelerra-gg.org/download/pkgs/ub18 
 bionic main

Save: Cntl+o then enter.

then:
Be aware it will take a minute to update. Let it do its thing.

sudo apt update 
sudo apt install cin

If you run into issues open the sources list again and remove the two Cinelerra lines and apt update again.

For complete removal:

sudo apt purge cin

Then remove the PPA from sources file. Delete anything related in home, like .cin or .cinelerra and the project folder if they exist.

To remove keeping cofigs:

audo apt remove cin
