Botched app install and schizophrenic Yunohost

Hi all !
I recently tried to install https://github.com/YunoHost-Apps/openvpn_ynh – everything seemed to be OK, until the ssh connection between my server and my local laptop dropped… The installation did not finish properly (I guess it required user input at some point), and now if I run :

root@Seedbox:~# yunohost app install https://github.com/YunoHost-Apps/openvpn_ynh
Error: openvpn is already installed
root@Seedbox:~# yunohost app remove https://github.com/YunoHost-Apps/openvpn_ynh
Error: https://github.com/YunoHost-Apps/openvpn_ynh is not installed

Needless to say, I’m stuck, and the YNH API seems just as lost as me.
Any idea ?
Thx !

FRENCH VERSION :
Hello tout le monde !
J’ai récemment essayé d’installer https://github.com/YunoHost-Apps/openvpn_ynh – ce qui semblait marcher sans problème, jusqu’au moment où la connection ssh s’est brisée (‘broken pipe’ blablabla)… Je suppose que l’installation avait besoin de l’utilisateur pour continuer à un certain point, et du coup elle ne s’est pas terminée proprement. Maintenant, si je tape :

root@Seedbox:~# yunohost app install https://github.com/YunoHost-Apps/openvpn_ynh
Error: openvpn is already installed
root@Seedbox:~# yunohost app remove https://github.com/YunoHost-Apps/openvpn_ynh
Error: https://github.com/YunoHost-Apps/openvpn_ynh is not installed

Apparemment l’API yunohost est tout aussi perdue que moi…
Une idée ?
Merci d’avance !

Okay, I solved it by rebooting and installing another app. I guess it forced Yunohost to “fix” its installed apps database ?
