You can change your current Transmission version, which is the latest version by default, to the one you want to get running. You can check the versions available via SSH with the following command:
ls -ld /opt/transmission*
The version number appears after the dash. For example, in transmission-4.0.5, the version is 4.0.5. If you want to use an older version, you need to copy the binary files from the /opt/transmission-version directory to ~/bin in your HOME directory.
mkdir -p ~/bin; cp /opt/transmission-4.0.5/bin/* ~/bin/
After copying the binaries, you also need to add the ~/bin directory to your PATH environment variable. Otherwise the system will still use the default Transmission binaries. You can do this automatically with the following command:
if ! grep -w "PATH=\$HOME/bin" ~/.bashrc ; then mkdir -p ~/bin && echo 'PATH=$HOME/bin:$PATH' >> ~/.bashrc && source ~/.bashrc ; fi
If you want to switch to a different version, use the following command and then log out and log back in via SSH:
rm -f ~/bin/transmission-*; cp /opt/transmission-4.0.6/bin/* ~/bin/
If you would like to revert to the default (latest) version, please run:
rm ~/bin/transmission-*
