no network connection to install from usb

[oldgeek]

I have been trying to install 12.04 LTS on my desktop, but every time I press install and choose English, the next panel says I'm not connected to internet. I KNOW I'm connected to internet, because it works with Rekong on the live image, but still won't acknowledge the connection when I try to install from the Live usb. I got the same results when I tried to install Ubuntu 12.04. This is a wired connection, by the way. Any ideas? Or should I just wait until 12.10 comes out and try that? I don't particularly like frequent clean installations and so Long Term Service seems right for me.
One other thing: once I get the connectivity problem solved, will I be able to install over my Kubuntu 11.04 partition, which is what I'm using now? If so, how would I do this?

If your 11.04 installation is working fine, you can simply upgrade that one, and avoid a complete reinstall.

sudo do-release-upgrade

Ive always had the same problem...my internet connection is fiesty. What I do is just skip connecting to the internet during install and configure it afterward. If you cant do this with the normal Live CD, download the alternate install CD image.

I have downloaded the 12.04.1 update and will try running it without internet, as you suggested. Which brings me to my second problem: I currently have 3 operating systems on 3 different partitions: Windows 7, Kubuntu 11.04 and Ubuntu 11.04. What I want to do is copy 12.04 directly onto my 11.04 partition, thereby erasing the latter and installing the former. My partition table looks like this:
/dev/sda1 0% (104.9 MB) Bootloader?
/dev/sda2 51.9% (259.6 GB) Presumably Windows 7
/dev/sda5 24% (120.3 GB) Presumably Kubuntu
/dev/sda7 22.3% (111.6 GB) Presumably Ubuntu
/dev/sda8 0.9% (4.3 GB) I have no idea what this is.

I assume I would have to do this through Manual but am not sure what steps I have to take. Any suggestions? Kubuntu is my min operating system so I want it to work right.
On the other hand, I'm a bit worried about my installation usb not being able to read that my computer is connected to internet. Recently my Lenovo netbook, which also runs on Kubuntu 11.04, stopped connecting to wireless, but only on Kubuntu, not on Windows 7. Is there another problem here?

[oldgeek]

I tried this, but was informed there was no upgrade. If I remember right, you could only upgrade to 12.04 from 11.10, not from 11.04. Thanks anyway.

yes ,,,,BUT you could "sudo do-release-upgrade" from 11.04 to 11.10 then fully update 11.10 and then "sudo do-release-upgrade" to 12.04 ,,,,,that’s how I got hear

now on a new note ,if you are unsure of what's in your partitions and who is controlling grub you may have more problems

like installing to the rong partition and wiping windows ,,,,installing over the installation controlling grub and failing to reinstall it to the right location !!

if you could post the output of

sudo parted -l

we may get a better idea of whats in what partition.

Here are the results of sudo parted -l:

Number Start End Size Type File system Flags
1 1049kB 106MB 105MB primary ntfs boot
2 106MB 260GB 260GB primary ntfs
3 260GB 500GB 240GB extended
5 260GB 380GB 120GB logical ext4
7 380GB 492GB 112GB logical ext4
8 492GB 496GB 4272MB logical linux-swap(v1)
6 496GB 500GB 4271MB logical linux-swap(v1)

[vinnywright]

looks like 1 & 2 are your windows 5&7 your linux installs and 8 & 6 both swap partitions , you should only need 1 both your linux installs would use it.
wile in one of your linux installs run

df -h

in a trminal and it will show you where / is (/dev/sda5 or6)

whitch one is controling grub now Kubuntu or Ubuntu?

VINNY

[oldgeek]

I ran df -h on Kubuntu's Konsole and it says that / is located on sda7:

Filesystem Size Used Avail Use% Mounted on
/dev/sda7 103G 35G 63G 36% /
none 2.0G 680K 2.0G 1% /dev
none 2.0G 2.7M 2.0G 1% /dev/shm
none 2.0G 92K 2.0G 1% /var/run
none 2.0G 0 2.0G 0% /var/lock

[vinnywright]

ok so Kubuntu is sda7 and ubuntu would be sda5 .

so which one is controlling grub ,,,,or do you use the windows boot loader?

VINNY

[oldgeek]

Presumably Kubuntu is controlling GRUB, as that's what loads if I don't do anything after turning the computer on.
Strange, but I thought Kubuntu was on sda5, as I installed it after Windows and before Ubuntu. When I tried to install 12.04, when it came to the partition step the guided choice wanted to divide sda5 into two and install 12.04 on one half of the partition. I didn't want 2 Kubuntus, so I cancelled, and here I am. Thanks for all your help, by the way.

[oldgeek]

I ran df -h on an Ubuntu terminal a minute ago, and got sda5 as a result. Which one is correct? And just what does the command do? I'm still a novice at this, I think.

that would be correct ,,,,df shows disk usage of the mounted file systems .........see "man df" (run in a terminal)

vinny@Vinnys-HP-G62:~$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 21G 12G 7.7G 61% /
udev 1.9G 4.0K 1.9G 1% /dev
tmpfs 751M 880K 750M 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 1.9G 184K 1.9G 1% /run/shm
/dev/sda3 196G 149G 38G 80% /home
vinny@Vinnys-HP-G62:~$

hear we see /dev/sda2 is mounted at / (thats root) this is the root system Kubuntu hear , and /dev/sda3 is mounted @ /home , this is my /home/vinny DIR I keep mounted on a separate partition.
we also see that the root system or / is a 21 Gig partition that has 12 Gig's used and 7.7 Gig's available ,so, 61% used

wile you were in Kubuntu it was displaying /dev/sda7 as that is the partition that Kubuntu is installed to , so it's / (root) is /dev/sda7
wile in Ubuntu you get /dev/sda5 becose that's where Ubuntu is installed to ,,, so Ubuntu's / is sda5

OK enough with class .....on to the lesson

first if you cant make Kubuntu upgrade from 11.04 to 11.10 to 12.04 and are going to reinstall to the current partition you want to save your files to some where else as your /home is in the root partition and will be destroyed during the reinstall .

then run the Kubuntu live cd/usb and at the partitioning phase select "manual" you will get a screen showing the partitions ,,,,select /dev/sda7 (I think you also haft to click change) ,,,,use as ext4,,,mount on / and yes format it ,,,,,,,,BEFORE you leave this page at the bottom is a drop down box for where to install grub ,,,,chose /sda or MBR I think it will show as /sda though . Then continue with the installation .

[oldgeek]

Thanks for the info. I would like to try the upgrade from 11.04 to 11.10. and then to 12.04, but don't know exactly how to do this. I tried typing sudo do-release-upgrade but was unable to to go further--error message said no upgrade was available. If I can't use the upgrade method I will try the method you mentioned in your last communication. So what do I type to get the upgrades? Again, I appreciate your time and effort to help me out.

[SteveRiley]

Try

sudo do-release-upgrade -d

Note the "-d" at the end.
