"the tor never started" -> Super confusing. Probably you mean "Tor Browser never started"?
Whonix doesn't ship a /usr/bin/i2prouter apparmor profile.
You can either:
1) reduce security, disable that apparmor profile.
sudo aa-disable /usr/bin/i2prouter
2) reduce even more security. totally disable apparmor (probably not required).
3) Or contact upstream (here: i2p) about this issue.
4) Adapt the apparmor profile yourself.
