kubuntu 17.10 still doesn't propose upgrade to 18.04

[allaf]

So I take it that you are not in a position where you can download the 18.04 ISO?
If so, your only recourse is to use the 17.10 ISO to re-install it. Then, doing nothing else, download the 18.04 ISO, CHECKSUM it, burn it, install it.
Don’t get tricky or try anything fancy.

Yes I did download the 18.04 iso and burned it on a usb stick but the install hangs in the early stages.
I did not chesumed it as i did on a old laptop on windows.

I think i'll try with another usb key, I'm gettiong desperate

You really need to validate the checksum against the sha256 sum provided for the Kubuntu ISO. It's not easy in Windows because you have to download some application, but it is easy in Kubuntu with the sha256sum. See if your Kubuntu install has it by using

which sha256sum

on the command line. Then run

sha256sum {ISO filename}

and compare the output number to the on provided on the Kubuntu download site. If any number or letter disagrees, it's a bad download.

I am tryingto install from another usb key and I get stuck at the exact same point.

I click on "Continue" and I get the cursor in waiting mode but it never goes on to the next step.

wtf is happening here ?

I went out do some shopping and I came back the screen did load finally.
it took maybe 20minutes.

Now i choose a manual install and when i click 'change' on one of my partition I get to wait again. Looks like a problem with a disk

Had to wait 10minutes to get my mouse pointer back, but i finally achieved to format / (btrfs) and launch the install !

[allaf]

ok I spoke to soon



Maybe I made a mistake, maybe it should be sdb actually I have to try again and wait 30minutes

[allaf]

Finally made it to the end.

it was a bad experience, thanks for the help

Wow. That's slow. Any msgs in the logs explaining why? Maybe a loop repeatedly attempting something without success?

[allaf]

no i didn't find anything in /var/log/message.

You can use systemd to give you a bootup list of processes, when they start and how long it takes them to start.
A basic listing is
systemd-analyze

Then there is
systemd-analyze blame

and
systemd-analyze plot > somename.svg (which can be read with your browser.)

See "man systemd-analyze"
