Oops! Someone saw a mistake I made…I actually uncommented some repositories multiple times. In case it helps someone, here’s what to look at…
There is a “deb” line to imply “.deb” binary files, a “deb-src” line to show source files. Then a URL. After this is the name of the release…the Ubuntu 16.04 is also known as “xenial”. Then a series of repositories are listed after this. There can be a single repository per line if desired, or if the URL is the same, multiple repositories after this. I had uncommented the lines with both single repos and multiple repos.
So having this one line:
deb http://ports.ubuntu.com/ubuntu-ports/ xenial main restricted universe multiverse
…is equivalent to having these four lines:
deb http://ports.ubuntu.com/ubuntu-ports/ xenial main
deb http://ports.ubuntu.com/ubuntu-ports/ xenial restricted
deb http://ports.ubuntu.com/ubuntu-ports/ xenial universe
deb http://ports.ubuntu.com/ubuntu-ports/ xenial multiverse
I don’t know why, but sometimes after the initial edit this doesn’t show as being included multiple times. There are advantages to using the tools for adding/removing repositories.
Here’s the actual sources.list without the repeats (pointed out by @Honey_Patouceul):
# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
# newer versions of the distribution.

Does anyone have an idea on how to get extended qt-creator samples with that method of installation from apt-get?
I was looking to start 3d bars example from qt , but did not have a chance to do that, because it is neither installed via apt-get nor it dependencies are installed.
[url]https://dw3i9sxi97owk.cloudfront.net/uploads/stream/2018/02/1274822/16194913/bars-example.png[/url]
I am just wondering if I need to compile the qt5 from sources to be able to access that example as it is said from the “Welcome” section of qt-creator.
Thanks.
Reference: Bars Example | Qt Data Visualization 5.10
Qt DataVisualization was commercial only, it has been included since Qt5.7, but current version on arm64 is Qt5.5. [url]https://wiki.qt.io/New_Features_in_Qt_5.7[/url]
You may find the package sources and build yourself.
Hi,linuxdev,
I just met the same problem as Mohsen_UTD. You mentioned to modify the contents of ‘sources.list’. I open the file on my computer and found that it is different from yours. I have no idea about how the change it. Would you please give me more detailed instructions? Thanks in advance!
My sources.list is :
[b]# deb cdrom:[Ubuntu 16.04.3 LTS Xenial Xerus - Release amd64 (20170801)]/ xenial main restricted
