thanks for the update arup.gonna download the 64 bit version now.been using 32 bit for some time now.i am planning to retain the home partition and format the root with ext4.will this cause any problems as i am planning to use the 64 bit version with my 32 bit home partition??
You are welcome clansman77, I don't foresee any such problems, x64 bit Ubuntu has no issues with x32 XP partition on my other PC. You can go ahead and install and enjoy the power of x64 computing which I have been doing since the x64 CPUs from AMD became common .
When will it be available for updating through Ubuntu
Should be very soon, probably sometime today. I'm running 8.04, so 9.04 will probably not show in update manager until I update to 8.10. Anyway, I find it quicker and easier to back up my data and do a fresh install. Plus, it's a lot of fun. Something to consider.
If you want to download it, use Bittorrent. I am maxing out my connection. If I try any of the mirrors it is a slow crawl.
Yep, torrent is the only way here, there is also apt-p2p which allows you to update your distro via the torrent. By using torrent the Ubuntu servers get full relief and you get way better speed.
You can download the iso, mount it and create it as a source repository and then upgrade from there.
https://help.ubuntu.com/community/Repositories/Ubuntu for more info.
Now. But I suggest to wait a bit. The repositories are rather slow ATM.
Best way to upgrade at full speed.
I upgraded to the RC a week ago or so. It's been stable and I had only one problem (that the installer warned about btw) and it was OnTv that stopped working, but otherwise runs perfectly.
I had intended to upgrade with the Alternate CD but then I decided to install anew by formating my root partition with ext4 while keeping my unchanged home partition with ext3.
And I really have to say: WOW! The performance gain is absolutely remarkable! You really feel the difference - and I'm not talking only about the considerably faster booting but about smoother operating and more responsive applications.
In the meanwhile I have converted ext3 to ext4 for the partition where I have my Virtualbox VMs and - using a Live CD - also for my home partition without any problems. It remains to be seen if that gives an additional performance boost, too. I doubt that, though, as I understand that the new ext4 features only apply to new (or altered) files. So the additional speed should become noticeable only after some time.
To cut a long story short: Go for ext4 if you want more speed.
I tried updating and it said it failed to update. I'll try later.
Can you opt for ext4 during the install? I'm going to download the final and reinstall everything. I assume you'd have to do manual partitioning and from there you could select ext4 for root and all partitions?
Yes you can but you have to manually select the partition.
Ok, no problem. Thanks Arup.
i believe grub doesn't support ext4 yet, you have to create a partition to boot or format /boot as ext3 and / as ext4.
That's kinda weird.... that's about as bad as all the x64 machines out there without any x64 flash for Win yet.... not quite, but still, if ext4 is here, why hasn't grub been updated to handle it?
There's two different grubs, the legacy version that they know works completely and is essentially bug free. Almost every distribution uses it. There's a v2 of grub that has all the fancy features and supports a ton more filesystems. Unfortunately, it is not completely stabilized.
To solve this problem, most distributions have patched the legacy version of grub with ext4 support. I would assume ubuntu has done this.
Thanks for the explanation Alpha.... Didn't know all that.
Since I dual boot with another linux distro, I hope that is the case. This thread has me wanting to install with ext4.
Ext4 filesystem support
Ubuntu 9.04 RC supports the option of installing the new ext4 file system. ext3 will remain the default filesystem for Jaunty, and we will consider ext4 as the default for the next release based on user feedback. There has been extensive discussion about the reliability of applications running on ext4 in the face of sudden system outages. Applications that use the conventional approach of writing data to a temporary file and renaming it to its final location will have their reliability expectations met in Ubuntu 9.04 beta; further discussion is ongoing in the kernel community.
Ext4 support in GRUB was provided by Colin King. If you choose to upgrade your / or /boot filesystem in place from ext2 or ext3 to ext4 (as documented on the ext4 wiki), then you must also use the grub-install command after upgrading to Ubuntu 9.04 RC to reinstall your boot loader. If you do not do this, then the version of GRUB installed in your boot sector will not be able to read the kernel from the ext4 filesystem and your system will fail to boot.
Ext4 support in gparted has been provided by Curtis Gedak.
Rest assured it will work.
Downloaded and installed (64-bit version), and here's two questions which hopefully someone can help me with:
1. Unlike Intrepid, Jaunty doesn't automount USB thumb drives anymore upon bootup. Any way to remedy this?
2. How do I stop the !@#$ing Update Manager from popping up constantly.
sudo apt-get install pysdm
Pop in your usb thumb drive and then go to system>administration>storage device manager and then select your usb drive to be automounted at boot.
I don't get any such update manager pop ups in around eight of the PCs I have installed Jaunty in.
Was one of the first things I tried. pysdm doesn't even see my USB drive. I have to pull it out and plug it back in for Ubuntu to recognize and mount it.
