Author of FreeFileSync publishes binaries for Ubuntu for each release. But you have to install them again and again, once a month. That’s why I am the maintainer of FreeFileSync PPA, the way in Ubuntu to distribute binaries with automatic updates.
As of May 2014, here are the FreeFileSync versions available for each Ubuntu series:
| Ubuntu series | Last available version of FreeFileSync | Supported ? | Comment |
|---|---|---|---|
| Natty | 4.0 | No | |
| Oneiric | 5.5 | No | |
| Precise | 5.21 | No | Requires newer libraries |
| Quantal | 5.23 | No | Requires newer libraries |
| Raring | 5.23 | No | Requires newer libraries |
| Saucy | 6.0 | Could be if asked | |
| Trusty | 6.5 | Yes |
