Upgrading from Ubuntu 13.10 to Ubuntu 14.04 ( low memory error )

[Vlad_Ulmeanu]

Hello ,
I have recently installed Ubuntu 13.04 alongside Windows 7 via WUBI, allocating Ubuntu 9.31 GB of memory .
Because I couldn't download anything from the software center, I upgraded to Ubuntu 13.10 and then to Ubuntu 14.04 LTS .
Before I could end the second installation, Ubuntu said that I have less then 400 MB remaining ( low memory ) , while Windows says that the partition has 1.62 GB free .

At the moment, I can't run Ubuntu, because this message shows up ( " some serious errors have been found " ) when I try to open Ubuntu .

What can I do now ?
Thanks ,
Vlad

( Ubuntu shows less than 400 MB free and Windows shows 1.62 GB free ) - might it be because for Ubuntu 1 MB = 1024 KB and for Windows 1 MB = 1000 KB ?

It's just a hypothesis, I don't know .

Wubi, Ubuntu 13.04 and Ubuntu 13.10 have all been unsupported for quite some time. Ubuntu needs the free space in the Ubuntu partition (which, in case of Wubi, is a virtual partition on the Windows partition). Windows reports free space on the Windows partition, but cannot look into the Ubuntu partition. And to prevent you and us from getting confused the next time, memory is RAM, the fast volatile memory of a computer. For permanent storage space we use the term disk space.

The best thing to do would be a clean install of Ubuntu 14.04 as a proper dual boot. You can make a backup of your Wubi system by making a backup of the file root.disk, which you can find on Windows. You can also access the root.disk file from an Ubuntu live disk and make backups of the files present.

Ubuntu said that I have less then 400 MB remaining ( low memory ) , while Windows says that the partition has 1.62 GB free .

If you install Ubuntu with Wubi, Ubuntu doesn't use the space of a whole real partition for system files.

df -h
shows you the difference:

The line with "/" the available space for system files:

/dev/loop0 18G 18G 18G 100% /
The line with "/host" the available space on your Windows partition:

/dev/sda1 100G 20G 80G 20% /host

A solution could be: How_do_I_resize_the_virtual_disks
(https://help.ubuntu.com/community/ResizeWubiDisk)
In your case (1.62 GB is not enough space to duplicate a virtual disk) a real resize is a better solution: Resize WubiDisk (https://help.ubuntu.com/community/ResizeWubiDisk)

But my recommended solution is to migrate virtual disks to real partitions: Migrate Wubi (https://help.ubuntu.com/community/MigrateWubi) OR this:


The best thing to do would be a clean install of Ubuntu 14.04 as a proper dual boot.

Thank you for your answers .

I uninstalled wubi and installed Ubuntu 14.04 from an USB .

However , I got another problem, which will be covered in another thread, because now it has noting to do with wubi .

Perhaps mark this thread as solved to help future travelers and post a link to the new thread if you'd like. Good luck. ;)
