Running Subtitle Edit in ubuntu.
You can run portable Subtitle Edit in linux. There is a discussion on the sub talk forum on how to run it.
You can run a basic version with video support. To do more advanced work I recommend using Windows. You can run Windows in Virtualbox on a mac.
You need to install mono-complete and Mplayer.
sudo apt install mono-complete
sudo apt install mplayer
If you open a video file in the Files/Nautilus file manager it asks if you want to install codecs.
I also installed these that enables more codecs:
sudo apt install vlc
sudo apt install mpv
(On Windows you can use mpv to use frame accurate seeking.)
