fail to install ubuntu server 14.04 64bit LTS from USB drive

Question

I created a bootable USB using Startup disk creator (in ubuntu desktop 12.04 32bit), from an iso image of Ubuntu server 14.04 64 bit, when I want to boot another computer using this usb drive, The computer boots up, the installation process ok, it gets through the selecting the language, then it shows me the error that it can't mount the cd-rom to continue the installation, I tried several times with others USB devices but it shows me the same error. How can I get this work ?

Solution 1

I solved this by using anther iso image !! I changed this image ubuntu-14.04.2-server-amd64.iso and used this one ubuntu-14.04.1-server-amd64.iso, and it worked like a charm using the same startup disk creator and the same USB. finally I think this is a bug in that version of ubuntu server, because I'm not the only one who get this error.

Solution 2

This is how i got it to work.

When it gets the CD-ROM error, move the install USB stick from one port, to another USB port on your PC. Then retry.

This worked. I don't know why.

Not only that but I was reinstalling 14.04 later that night, and the CD-ROM error did not happen again. The 2nd install went without a hitch.

Yes it worked for me also.

Solution 3

Problem is that the new image isn't meant to be used with unetbootin or any of the normal USB creators.

Just use dd like:

dd if=ubuntu-14.04.2-server-amd64.iso of=/dev/sdb bs=16M

(obviously, replace /dev/sdb with the path to your USB key, but don't use any partitions (i.e. don't use /dev/sdb1, /dev/sdb2, etc -- just the whole device)

http://ubuntuforums.org/showthread.php?t=2253860 has an answer.

Here are the steps that I took to get it to work

1. When you get the error, Alt+F2 to a second console.
2. Find out which device your USB stick is (tail -n 100 /var/log/syslog)
3. If the device is busy, umount it (umount /dev/sd[abcdef]1)
4. Then mount it to /cdrom (mount -t vfat /dev/sd[abcdef]1 /cdrom)
5. Alt+F1 to get back to the install console, and try detecting again

Solution 5

With the installation CD ubuntu-14.04.2-server-amd64.iso I ran into the same issue, for me it was as easy as running: umount /dev/sdc1

My tail -n 20 /var/log/syslog showed that the installer tried multiple times to mount /dev/sdc1 but since it was already mounted to /media that obviously failed.

With the above command I unmounted the USB-CD-Drive and the following attempt to automatically mount succeeded right away. After Alt+F2 just check what is currently mounted by issuing mount in the command prompt.

Thank you for your question, I tried something like this, I did Alt-F2 to open a console, I tried to mount the USB myself by the command, but it failed and show me the same error. At the end I solve this by using anther iso image !! I changed this image ubuntu-14.04.2-server-amd64.iso and used this one ubuntu-14.04.1-server-amd64.iso, and it worked like a charm using the same startup disk creator and the same USB. finally I think this is a bug in that version of ubuntu server, because I'm not the only one who get this error.

There is no ubuntu-14.04.1-server-amd64.iso - there is a ...amd64+mac.iso which I am assuming is equivalent. I also tried the umount advice which did get me past the initial error, but then "Unable to find 'pool/main/l/linux-lts-utopic/block-modules-3.16.0-generic-d‌​i_3_10.0.40~10.04.1_‌​amd64.udeb' came up. 14.04.2 doesn't seem USB friendly at all :/

I'm to confirm that the "switch USB port" trick works on my machine. Very weird...

[Jeff Atwood]

Yes this worked for me too!

[CᴴᵁᴮᴮʸNᴵᴺᴶᴬ]

Amazing fix - worked a treat with 14.04.3 server amd64 too

[sushicutta]

worked for me as well

[Judge2020]

That's very weird, worked for me too.

This is what I did (in ubuntu server 15.10) but the problem still occurs.

[niboshi]

Did not work for me, unfortunately (Ubuntu Server 15.10)

Works perfectly! For OS X, use sudo dd if=ubuntu-14.04.3-server-amd64.iso of=/dev/rdiskX. Check for USB drive using diskutil list.

This is a nice idea, but it's useless if you don't have a existing linux install.

[Piku]

While this isn't the best solution, it gets my vote simply because it involves less effort. I'm installing Ubuntu Server, I don't need any extra weird hoops to jump through, after all ;-)

[ultrajohn]

worked for me as well very well

[Homer6]

Worked for me on 14.04.4

resource busy on OSX? goo.gl/6rZFpv

[animekun]

well, on OSX this tutorial helped me a lot: computers.tutsplus.com/tutorials/…

@SpacenJasset It does appear to be the most correct answer. But in my case it just didn't work.

@Monkpit Your comment got me further than any of the answers. But upon finishing the install I am now left with a system configured to only install packages from cdrom, which means it won't download packages from the Ubuntu repositories, which is what I really need.

[kevy]

but this method not going to work with Ubuntu server CDs

Worked for me 16.04.3 server
