kubuntu 17.10 still doesn't propose upgrade to 18.04

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"

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

[GreyGeek]

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

[allaf]

Finally made it to the end.

it was a bad experience, thanks for the help

[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]

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

[allaf]

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

[allaf]

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 ?

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.

[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

I tried to reinstall lots of stuff like sddm xorg etc... now when i boot i don't even get to a login terminal. The loading is stuck at some point with a dot blinking continuisly...

don't know what the **** to do.

should never have tried to update, shouldn't have trusted it

[allaf]

I did manage somehow to fix dpkg problem I think via the grub repair entry. I had to do so many things i don't even remember what i did.

But when I boot I get an ascii style loading screen instead of a nice animated picture and kde doesn't launch I get a login screen on tty1
and I have no graphic interface on tt7.

How do I reinstall everything cleanly ?

If i type apt install plasma-desktop I get "package is already installed"

thx

[allaf]

thx but apt --reinstall doesn't work as I always get that ****ing keyboard-configuration package error.
So i cant' install anything.

I decided to install from scratch, booting from a usb key, but then the install hangs just before the "Disk setup" step !!

I'm ****ing fed up with this ****...

[GreyGeek]

IMO, the best course of action you can take is to scrap the install of 17.10, which was at its EndOfLive two months ago, and install Kubuntu 18.04LTS, which has an EOL of 23.04.

IF you don't do that then:

EXT3 is old. If you aren't going to try Btrfs then EXT4 is what you want to use, but that would require a reinstall. If you do that see my point above.

If you decide to continue on:
IF repeating these 3 or 4 times:
sudo apt -f install
sudo dpkg --configure -a

produces no errors then I would reinstall the plasma-desktop to make sure all of its components are installed/updated.
sudo apt update
sudo apt install --reinstall plasma-desktop

If that comes back clean then I'd do a reboot. If the reboot fails you can go into the recovery option from the grub menu.
Otherwise, I'd go on to installing the nvidia-390 driver to get your accelerated graphics back.
Once you get everything back and running right install TimeShift from:

and use it to make backups of your system.
