This question already has an answer here:
Installed Elementary OS Loki on the following configuration
Intel NUC6i7KYK, 16 GB memory, Samsung 850 EVO storage.
Install was smooth - no issues. Completely clean install, the system had no OS before the install.
App Center: Told me I had updates but clicking on update did not work for any item. Got the message "Waiting to be queued". I used apt-get after that for all new app installs and updates. Post updating all the apps now App Center freezes
Other than that it has been a smooth experience - nice light weight OS.
Where can I file bugs?
