uGet is Already Installed!
uGet 1.10.4 comes preinstalled in Semplice 7.0.1 as the default download manager.
Install via the Semplice repositories
Semplice ships a significantly old version of uGet so it is recommended to upgrade immediately. You can upgrade to uGet 2.0.8 in Semplice by doing the standard apt upgrade command.
Semplice is based on Debian Sid (Unstable) so you can also upgrade by using one of the downloadable deb files.
Install the aria2 Plugin
Semplice does not install the aria2 plugin by default but you can easily install aria2 1.30.0 from the repository.
