Bonjour
J'ai installé glimpse en konsole mais il n'apparaît pas quand Je le demande. Parce que si Je le demande sur le menu, on voit " Éxécuter glimpse" . Je clique mais rien n'arrive.
Je suis sous Ubuntu 18.04
Merci
Tu l'as installé à quel format : deb, snap, flatpak, appimage... ?

Est-ce que tu as essayé de relancer la session au cas où ?

À tout hasard, qu'est-ce que ça donne si tu tapes glimpse dans un terminal ? Selon la façon dont il a été installé, il ne trouvera peut-être pas la commande, c'est surtout pour voir s'il y a des erreurs dans le cas où il la trouve ?
Bonjour et merci
Est-ce une application seulement en ligne de texte?

Je l'a installé avec snap

Il y a un Glimpse qui est un fork de GIMP et qui est a priori le soft que tu veux utiliser et il y a apparemment une deuxième appli en ligne de commande − qui sert à je ne sais quoi − et qui est celle qui se lance quand tu tapes la commande glimpse.

On est d'accord que le Glimpse que tu veux utiliser est le fork de GIMP ?

Donne le retour de :
dpkg -l | grep glimpse
snap list

En révisant mon post, Je m'en excuse et Je corrige:
Voici ce que donnent tes commandes.
Tu n'as pas répondu : le Glimpse que tu veux installer, c'est bien le fork de GIMP (l'éditeur d'images, celui-là) ?

Actuellement, tu as l'autre Glimpse, un soft en ligne de commande qui sert apparemment à faire des recherches de fichiers.

Si c'est bien l'éditeur d'images que tu veux, supprime l'autre :
sudo apt-get remove --purge glimpse
puis installe le bon. Tu as trois formats disponibles selon ce que tu préfères :
- snap
- flatpak
- appimage
Si tu veux un format deb, il n'est pas dans les dépôts Ubuntu, il faudrait fouiller pour voir s'il existe un PPA qui le maintient mais c'est pas sûr.
