I really really need to upgrade my laptop's linux, it's running Mandriva 2006 and it can't do Firefox 3 or Flash 10 for reasons of library oldness.
I tried to upgrade to Ubuntu from a live CD once a few years ago but it wouldn't install unless it reformatted the disk (it's EXT3). Is it possible to install ubuntu from a live CD or some other CD without it reformatting? If not, I'll just install Mandriva 2010.
Also I read once that Ubuntu had a feature that let you upgrade versions like if you installed Windows 2000 and you could run a command to upgrade to Windows XP, then later to Windows 7 (with no need to download and install XP or Win7). What is the version update feature called? so I can google it
I would love it if I never have to install the old way again.
I don't think it's required to reformat the hard drive I've installed old mandrake and the previous mandriva linux over the previous versions and it didn't need to install to a newly created partition.
If the old linux distros can do it, then there should be a way the almighty ubuntu can do it, I would hope.
The partition is already there and formatted.
My backup drive is formatted as NTFS and it's NTFS driver is too old to write to it.
if you have enough space left on the drive try booting into a liveCD and making a backup partition on the HDD. Than copy all your important files onto the backup partition. Install ubuntu on the old partition and copy your data back.
To avoid this in the future i would advice partitioning your disks to take advantage of some of linux's better though out features.
Mine old one looks like this:
sda1 ext2 /boot 200mb
sda2 swap swap 767mb
sda3 ext4 / 12gb
sda5 ext3 /home 200gb
Having a boot sector means that even if your file system gets damaged you should be able to at least get grub running and even boot into another OS or even repair linux. The /home directory means all your personal data will be stored on its own partition, this will allow for reinstalls, upgrades, crashes, etc without loosing anything. The root partition its self does not need to be that large depending on the programs you have installed.
Definitely agreed on having /home in its own partition. I'd say / typically only needs 10 GB absolute maximum. A separate /boot partition is not necessary and can be a little confusing to have, but if you know what you're doing it can be a good idea.
i find that for a seperate boot partition is very important. Say you are doing something on your computer and it hard crashes, and corrupts the root beyond repair. You will not loose grub if it is on its own partition meaning that you can still boot. But that is just my opinion, I've also had this happen a few times so i may be a little paranoid.
A question that keeps tossed around every new Ubuntu release is what's better a clean install or an upgrade? . Common wisdom would suggest that a clean install would probably be better, however the inconvenience of losing current installed apps and configuration makes most of us shy away from this path. But you could have the good of both worlds A fresh install and keeping your apps and configuration intact
Just backup your /home folder onto an external drive or whatever. Make sure you also grab the hidden files, it would also be wise to have your /home in a seperate partition, back up /etc, and use the tar command to back up home (it will preserve your structure and permissions)
I installed kubuntu last night and I found out that the installer didn't need to reformat the disk. The installer deletes the important directories, but not all of them because the installer crashed because a directory already existed. I tried again with the formatting. I kept a terminal window open and got a few cd-rom errors (via dmesg command) during the install but the install seems to be ok.
I can finally run Firefox 3.5 and Flash 10 on it.
It is correct, there is no need of reformatting the partition to upgrade Linux distros, unless the distro doesn't provide a good package manager. Distros like, Debian, Fedora, Mandriva, (*)ubuntu, Gentoo, Arch Linux will allow you to upgrade easily.
The best time to reformat during an upgrade is to fix a problem that maybe you can't fix unless you do reformat and install the newer distro.
