When I try to install a new app (a code editor in this case, brackets) I click on install but it doesn't work. When I want to install new updates available from Ubuntu Software it does this: I click on install, then it asks me for the admin password, I write it, the install bar gets full and stays like this for ever. No installation.
Please what could the problem be? I read other topics about this same problem but it doesn't seem to go away
