Upgrading from 14.04LTS to 16.04LTS

[KieranFitzgerald]

Trying to update but I am having problems getting started. I selected upgrade from the software updater. I get an out of disk space error, screen shot uploaded. No further details provided. I have an SSD with boot & system partitions. home is on my HDD all appear to have space.
Last time I tried others suggested removing old Linux kernels which I have done but no change.

If I try to upgrade from the command line I get an internet connection error see second screen shot. Press OK still offers an upgrade but also give out of space error.

What do I do now?

I've encountered that warning. The update manager needs sufficient space to store all the downloaded files which can be a lot. If you make some room by temporarily moving enough data files to temporary storage or enlarge the root partition by a few GB, it should go through.

My root partition is on the ssd I am trying to increase the size but I have a Windows reserved partition in the way. This has an error according to Gparted so I can't move it. Windows works fine so no idea why it's reporting an error or how to fix it. Can I relocate root to the hard disk?

Edit Gparted reports "unknown" file system for the reserved partition.

I managed to get 6GB more for root but still not big enough.

Just backup your data and do a clean install, much faster and safer.

You can relocate the root partition to the HDD, but you'll lose the advantages of having it on the SSD. Moving it will be more work than a fresh install, especially as you already have a /home partition. So try a fresh install.

I tried a clean install last night using the "something else" option. got message No root file system is defined! How should I prepare my SSD (sda) and HDD (sdb) for the install? sdc is for backup.

This my current partition scheme


kieran@Desktop:~$ sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABELNAME FSTYPE SIZE MOUNTPOINT LABEL
sda 111.8G
├─sda1 vfat 487M /boot/efi
├─sda2 ext4 25.7G /
├─sda3 ext4 15.3G /usr
├─sda4 128M
└─sda5 ntfs 58.5G
sdb 931.5G
├─sdb1 ext4 3.7G /var
├─sdb2 swap 4.7G [SWAP]
├─sdb3 ext4 727.4G /home
└─sdb4 ntfs 175.8G
sdc 232.9G
└─sdc1 ext4 232.9G Data
sr0 1024M

sda2 is /root (should I label it?)
Windows on the ntfs partitions

Want to keep Windows and home.

got message No root file system is defined

In the installer window, when you select the partition for the " / " (root filesystem) you need to click the Change button below the main window and select the Mount point option " / " which is the first option from the drop down menu. So in your case, if you want sda2 as the / partition, click sda2 in the main window, click Change and then select / for Mount point.

[Impavidus]

Select sda2, click "change", set the mountpoint to / and mark it for formatting. Select sdb3, click "change", set the mountpoint to /home and make sure it's not marked for formatting. I think the installer should recognise the efi and swap partitions automatically. Unless you have some special needs, there's no need for /var and /usr partitions.

16.04LTS installed and mostly working. I can't boot Windows . Ran boot repair from live session. No change.
