The software updater do not propose me to upgrade to 18.04 as you can see on the screenshot.
I tried update-manager -cd but have no effect still showing the 17.10 version
So i got a question: Does U-M 18.04 still in testing process that the software updater does not want to show us the 18.04 LTS ?
Upgrade to 17.10 first. One should always be as up-to-date as possible for a upgrade.
Have you tried changing the settings Software & Updates → Updates → Notify me of a new Ubuntu version to For long-term support versions, then running update-manager -c -d ?
Thanks for your answers. 
@elcste => Yes it was like that but when U-M 18.04 LTS went out it never propose me the 18.04, so i did put the "For any new version" and it's the 17.10 that shows up 
So i put back for long term support like below
And now no more 17.10 , it came back like it was before without showing anything not even the 18.04
I am quite confused because this happen on all of my computers (2 at home), and even at work (4 at my office)
All on U-M 16.04.4 LTS :scratchingHead:
I read some where that the latest LTS notifier for an 18.04 update won’t come out till August
If your 16.04 is working fine I strongly recommend you stick with it for now. Waiting for 18.04.1 is probably the smart upgrade path.
@decrepit : Ah Ok, i feel better now 
@Isaiah_Sellassie : I will take your advice, because, indeed all the 16.04 i have (home and office) work like a charm and very happy with them, so i can wait for the new whistle and bells 
Thanks a lot for your answers.
@decrepit
I read that aswell, although I was sure it was July. Everyone seems to be in a distro-dayz
shall put event in lightning extension, for the end of July to spend a couple of days acclimatizing to 18.04.1
although thunderbird (eMail/RSS2.0) has yet to become a snappy thunderbird.
Some differing opinions it seems.
I asked about upgrading from Mate 16.04 to 17.10 on the main Ubuntu forums and was advised not to do this but jump straight to 18.04.1 - which, incidentally, people do agree will not appear in Software Updater until later in the year. This is allow enough time for any major bugs to be ironed out, apparently.
So, yes. Like the OP I’ve got my LTS version switched on but will ignore 17.10 until 18.04.01 appears as the upgrade option.
OK now I know the “usual” date of upgrade for the LTSs via the software updater
it’s at the version xx.04.1 (example: 18.04.1) and this year is around the 26th of July .
The number of people upgrading an existing Ubuntu installation is about a quarter of those who are installing 18.04LTS from scratch which, given that we only start prompting for upgrade when the .1 release is out (scheduled for July 26th) is unsurprising.

18.04.1 has not solved any of my issues. In fact, Caja has gotten worse----crashes a lot, sometimes forcing a hard reboot. It’s wise to skip 18.04 altogether, and test 20.04.1 thoroughly in a VM before upgrading.
GIMP and WINE work very well. Everything else is unstable, unreliable. Thunderbird loses the ability to send mail sometimes, reporting a non existent problem with secure login. The web browsers are absolute horrors! I have Chrome, Firefox and Brave----all 3 hog enormous amounts of CPU and RAM, far more than in Windows. Full HD videos will not stream at all on the 2nd gen. i7, some 720p videos will manage to stream just about. The max reliable streaming of video is at 480p.
The 4th gen. i7 does stream videos but if a 1080p is streaming the system is maxed out basically. A mouse click takes 3-5 seconds to register. Compiz goes into slow motion. When UM is idling it uses 20-25% of the CPU continuously----by contrast, Windows 10 uses 2-4% of CPU to idle. How the tables have turned!
18.04 has been my worst computing experience since Windows 98 1st edition. The Linux desktop has hit a stone wall dead end----if it is not faster and more stable than Windows, what’s the point?
When I click on the ‘Upgrade’ button to go from 18.04 to 18.1, nothing happens. There is CPU activity for a few seconds, and then nothing.
Agree Fully.16.04 was the end of Ubuntu as far as I'm concerned. Until July I owned a manufacturing plant that was humming along smoothly on 16.04. Then on my machine which is the company's test machine, my Crucial SSDs started throwing bad reads. I contacted Crucial which said that 3 years was the expected life. I found my receipt and saw mine are 4 years old.
Unfortunately, the way I do backups (once a month, remove the active drive, install the oldest one then ClonZilla the current drive onto the installed one) quickly propagated the bad bytes. Once a year I clone the current drive onto a rotating drive.
So, based on some very bad advice I got from someone on one of these forums, I installed18.04. I could not imagine turd any larger than Ubuntu phone and Unity but this release became the champion. Finally someone from Canonical answered my plea and stated that there was NOT an import mechanism. Maybe next release. I have 15+ years of correspondence on that 16.04 rotating drive.
I could not find my old install media so I downloaded a new 16.04 ISO from Ubuntu and installed it. Guess what? They've "upgraded" TB to rev 60 (current) so now it won't read my old data.
Yesterday I veered off the LTS route and installed 19.04. Still no TB mail import! Someone has written a plug-in that's supposed to work but it doesn't. I spent today looking at the script (did I mention how much I hate JS?!). I found hard-coded paths everywhere and they don't all point to the same place. Looks like tomorrow is going to be a fun-filled day of byte-editing...
Fortunately in August I sold the company so I'm now going to retire comfortably. My "computer" will be an android net-book with cellphone connectivity built in. I'm going to be just a user.

I sympathize completely, John. I returned to Linux after a number of years, and 16.04---after all the tinkering and customizing---proved to be so good that it lulled me into a sense of over confidence. I made the unforgivable mistake of not keeping an image backup of the drive, before running the upgrade.
Nothing that was broken got fixed by updates of 18.04. How do you manage to break cron, for heaven's sakes? Instead, more things started breaking. Now, both my WINE apps are broken. The Foobar music player window cannot be moved or resized. (I never got the WASAPI direct access to my USB sound card to work on 18.04.) I have a blockchain app that spontaneously disconnects from the network (used to work perfectly on 16.04) --- my ranking on the network has been wrecked by these frequent disconnects, and manual reboots. I have never known a Linux system as crappy as this. In my past experience, it takes a while tinkering at the CLI and editing .conf files, etc. but once you've got it done, it runs fast and stable. Not any more---it updates endlessly, and degrades over time.
Thunderbird is working for me. Xsane, GIMP and Transmission are reliable. Firefox is rubbish now. Even VLC has problems intermittently. There is a Plex media server running fine, which is a 3rd party app.
I hung in there for a full year, with the endless typing of sudo password, and manual mounting of Samba directories in CLI, etc. and finally returned to Windows 7 on a new hardware. I am humming along now, with 1 or 2 minor irritants, which is normal for Windows. I will continue to use Samba as my LAN file server, and store all my data on Ext4 through it. It also runs a 3rd party cloud backup app. I am satisfied with Linux as a file server.
The desktop is going nowhere. I'll see how 20.04 turns out. It could be that 18.04 was an anomaly, and everything will return to 16.04 standard again. It's possible, but somehow I doubt it. The development model's weakness has been exposed thoroughly---I don't need it to be "free".
Thanks for the quick reply.
Never fear, 19 is the worst yet. I sold my company and retired last July. I see my future computing needs being met by an Android netbook.
What double ■■■■■■ me off with Shuttleworth's squandering resources on that phone and Unity is that I've made considerable donations over the years. I think I have a stake in this.

Congrats! Enjoy your retirement. I couldn't bring myself to use a Google product now, but that Android should get the job done for you. Less resource intensive than Windows 10 probably. I find my iphone with the plus size screen is plenty enough for me when I'm not at the desk.
Fully agree on Google products. But what choice do we have? Windows?
I'd rather die than go back there. Apple? Not in a million years.
That leaves Android. Let's pray that the the trust-busters will go at
them hard after the election.
Thanks for the good thoughts in retirement.
John
