subtitle
I'm a subtitle translator in Sri Lanka. So, I used Subtitle Edit (http://www.nikse.dk/subtitleedit) in Windows to create/edit/translate subtitles into Sinhala language.
But, is it possible to install it in Ubuntu? I have the latest version of Ubuntu with all updates.
Another tool to merge subtitles is DualSub (http://dualsub.sourceforge.net/). It works with SRT subtitles for input and output. It has many options for customization. In addition you can use it to translate subtitles to any language.
I see several issues with your command:
All filtering should be within one filtergraph.
You have many contradicting commands: for example you use the scale video filter, then you use -target which will scale, and you use -s which will also scale. You use -acodec copy to stream copy the audio, but you also include -ac 2 to force stereo. These are mutually exclusive so something is being ignored.
You placed options after the output. I'm not sure how ffmpeg will interpret that. Option placement matters.
ffmpeg -y -i input.mkv -filter_complex "[0:v:0][0:s:0]overlay[vid]" -map "[vid]" -map 0:a \
-target pal-dvd -acodec copy -t 60 output.mpg
Your video is 720x336, but your subtitles are 720x480. You may have to use crop on the subtitles before using overlay:
[0:s:0]crop=iw:336[s1];[0:v:0][s1]overlay[vid]
Or alternatively you could use a negative value on the y coordinate in overlay:
[0:v:0][0:s:0]overlay=0:H-h[vid]

You can get the Ubuntu compatible version here:

At the moment, this is 3.2 not 3.3 like you requested, but one user writes:
The comments also suggest that the package requires Mono:
