After installation of Bionic the system says it's Linux Mint 18.3?

[cogitans]

I’ve been using Linux Mint for several years now. But now I decided to go to Ubuntu as the terms of Ubuntu changed.


So I downloaded “ubuntu-18.04-desktop-amd64.iso” and installed it. I installed a few programs that I’m fond of.


But now i began optimizing the system itself. And now things slowly began to confuse me. Several places the system told me that my system is Linux Mint 18.3. That’s pretty strange to say the least. I did a format of my partition when I did the install so leftover files from Linux Mint can’t be the issue.


I compared the 2 files from Ubuntu and Linux Mint. They aren’t of the same name and my used iso-file is of the same name that Ubuntu presents.


I did several systemcalls:


“cat /etc/lsb-release”
->
DISTRIB_ID=LinuxMint
DISTRIB_RELEASE=18.3
DISTRIB_CODENAME=sylvia
DISTRIB_DESCRIPTION=“Linux Mint 18.3 Sylvia”


“head -11 /usr/share/mintsources/rebecca/mintsources.conf”
->
[general]
description=Linux Mint 17.1 "Rebecca"
codename=rebecca
base_codename=trusty
use_ppas=true

[mirrors]
default=http://packages.linuxmint.com
base_default=http://archive.ubuntu.com/ubuntu
mirrors=/usr/share/python-apt/templates/LinuxMint.mirrors
base_mirrors=/usr/share/python-apt/templates/Ubuntu.mirrors


I was almost sure that somehow I got the iso of Linux Mint downloaded and installed and I was just about to do a redownload and install everything from scratch…again.


Then I wanted to make sure that the visuals agreed on my discoveries. And on
https://www.ubuntu.com/desktop
then desktop of Ubuntu looks just the same as my desktop although my system states that I’m using Linux Mint 18.3.


What’s going on here?
Has the mirrors of Ubuntus downloads been tampered with so some are pointing to Linux Mints servers?
How come the visuals are the same concerning the desktop?
I did all of these discoveries as I somehow noticed that there was a folder named “linuxmint” in “/usr/lib/linuxmint/mintSources/mintSources.py” during my updates. That’s pretty strange, too, if I’m on Ubuntu Bionic.

What’s going on here???


PS:
I’ve got my Home-directory on a partition separate from the main system. It shouldn’t have any influenze on the systemfiles on my systempartition. But I though it was worth mentioning that my Home-folder is the only thing I’ve got from my old Linux Mint (with some configuration-files on it).


PPS:
Oh, by the way: as the iso of Ubuntu 18.04 destroyed my GRUB during installation (several attempts) and as “boot-repair” wasn’t able to fix it I installed the system from an iso of Ubuntu 16.04 and did a distribution-upgrade.

PPPS:
And I can't locate any windows concerning Additional Drivers as stated here:
https://www.makeuseof.com/tag/install-proprietary-graphics-drivers-ubuntu-fedora-linux/

PPPPS:
The command "cat /etc/apt/sources.list" states this confusing output:

If you tried to install Ubuntu in the Linux Mint partition, there is a chance that you didn't use the format option for that partition and that is why some files remain

[PaulW2U]

I did a format of my partition when I did the install so leftover files from Linux Mint can’t be the issue.
cogitans, further to our exchange of comments which started at https://community.ubuntu.com/t/bionic-based-on-linux-mint-18-3/5844, please confirm how your disk is partitioned and which partitions you formatted. Thanks.

[cogitans]

As stated in the question:
"I did a format of my partition when I did the install so leftover files from Linux Mint can’t be the issue."

I've got decades of experience in partitioning so this isn't the issue. But to answer your question:

My (entire) OS-harddrive
/dev/sdc1 ext4 Mount: / Size: 119.24GB Used: 11.36GB

Hmm, I'm trying to install the correct drivers, too. But I can't seem to find any place (GUI) to it through (I managed to do it from the terminal, though). As stated here:
https://www.makeuseof.com/tag/install-proprietary-graphics-drivers-ubuntu-fedora-linux/

neither any "Additional Drivers" shows in searching for "drivers" or going to "Menu > Administration > Driver Manager" (there's nothing of the name "Driver Manager").

[PaulW2U]

My (entire) OS-harddrive
/dev/sdc1 ext4 Mount: / Size: 119.24GB Used: 11.36GB
Thanks for that confirmation. So to summarise:


You have one partition on /dev/sdc for Ubuntu 18.04 which as been formatted
You have both xenial and bionic referred to in your repository sources
lsb-release -a indicates you have Linux Mint installed
But you actually see Ubuntu 18.04, i.e. GNOME Shell as your desktop
A number of other minor issues compared to the above

As a tester of most of the Ubuntu flavours for the 18.04 release I am totally confused by your experience of installing Ubuntu 18.04 on a newly formatted partition. Hopefully some else can throw some light on what you are seeing.

[jbicha]

I installed a few programs that I’m fond of.


Did you install programs from Linux Mint? What files do you have in
/etc/apt/sources.list.d ?

[jeremy31]

jbicha That info is at the bottom of the original post

I have only seen similar things happen when not formatting the partition and even then I would have thought that the Ubuntu install would have replaced /etc/lsb-release

[jbicha]

@jeremy31, my question was slightly different than what was posted at the bottom of the original post. I'm particularly interested in whether he has PPAs enabled.

[PaulW2U]

jbicha That info is at the bottom of the original post
the info quoted is the contents of /etc/sources.list. jbicha asked to see the listing at /etc/sources.list.d/

I have only seen similar things happen when not formatting the partition and even then I would have thought that the Ubuntu install would have replaced /etc/lsb-release
Agreed, even if you don't ask for your / partition to be formatted the installer still replaces part of it and installs such files as /etc/lsb-release with the new version.

Yep, I'm quite confused, too :-/

The only explanation I can come to think of is that some heavy configuration-files are located on my HOME-partition that takes control of my entire system more or less (my HOME-partition has been used for several versions of Linux Mint).
1:
But is that even possible? I mean for some configuration-files on the HOME-partition to that thorough effect on the system?

2:
I'm pretty much ready to do a reformat and rei-nstallation of the system. Does any utility like "Deja Cup" (wasn't that the name of it?) usable for Ubuntu 18.04 to register the installed programs so that I can quickly reinstall them after a system-re-installation?

I guess some of those are for Mint, right?

[cogitans]

Well, I installed Mint Backup now, took a copy of the output of programs listed in this thread and went through the "Show programs" for installed programs.
Now I'll try a reinstall of Ubuntu.

Thanks for your help :-)
