I have had lots of issues with the Software Center in the past as well. I just blamed it on Gnome and used the CLI anyway, as I'm more comfortable seeing what exactly happens in case it goes wrong. But it seems it has been fixed now because it's been month (maybe even a year or two, I couldn't say) that I've not had to complain.
(But yeah, to each their own, in the end it's not really important)
Are we gatekeeping being rejected now?
