Why is de Linux repository still on 0.8.5 but the client 0.9.2?
sudo apt-get install seadrive-daemon
seadrive-daemon is already the newest version (0.8.5).
The repositories have not been updated in quite a while now. There have been many requests for them to be updated. The same issue exists with the Linux Seafile Client also.
But the biggest problem is that SeaDrive is not OpenSource, so you can’t compile it yourself.
