Kubuntu 15.04: released with major issues - what's the logic?

[Qqmike]

OK that output just confirms you have a standard MBR system (not the newer UEFI firmware + GPT). That's OK. fdisk tells me that. (So does gdisk (no GPT present)--if GPT were present, gdisk would have told us all about it, in detail.)

The question remains about the encryption, you might have to bump this to get someone's attention on that.

As for installing another 15.04 OS, you do have to have the available space.

df -hT

should tell you how much space remains. Or in 14.10, fire up gparted Partition Editor and it should show you the available space on each partition.

You need available space so you can have room for 15.04. You should have a minimum of 6 GB for the root / partition plus some space for your home files or separate /home partition. If you have already used all available space on that disk, then you would have to shrink an existing partition to make room for 15.04. I'm not sure what you have in those Linux filesystems, sda5 and sda6: maybe root of 14.10 in sda6? /home is sda5? You have to think this through to determine if you will shrink and/or move any partition(s) to make room for 15.04. If you are shrinking/moving your home files for 14.10, you sure want to have a backup of those files! GParted is extremely safe and reliable, I have never had a data loss, but--as they will tell you @ GParted--risks do exist.

No, not too much information! Very helpful, in fact. I may not get started on this for about a day, but definitely want to move forward if possible. Thanks for your detailed help.

So here's the disk info. you suggested I post:

Question: Advice on encryption, anyone? -->

Conceptually, adding 15.04 is simple:

Use GParted to create new partition(s) for 15.04 (the root partition /, how about a separate /home partition?, and it can share the /swap partition created already for 14.10 so no need to create another /swap partition). You can use GParted live CD/USB, or even boot into 14.10, install gparted, and run gparted from there ASSUMING you will not be changing the 14.10 partition in any way (e.g., shrinking it) or moving it. (To install gparted from 14.10, you can use Muon Package Manager; it will show up, probably, under K > Applications > System > Partition Editor (GParted).)

Then run the 15.04 installer DVD/USB, choose the Manual install method when that screen comes up, then on the partition setup screen, identify and use the newly created partitions for 15.04 (root / and /home). And continue the installation. You have one HDD, sounds like. If you are asked, GRUB can go into /dev/sda (the MBR of your HDD) -- I'm assuming you do not have UEFI, the newer firmware.

But, I know nothing about encryption, except reading the posts, I know you need to pay attention to that! So someone will chime in.

First, to help any helpers, from 14.10, you might run two commands and post the output. This will show us what is on your HDD and where it is. (It will be more readable if you post the output of each between code tags, if you know how. Or use the forum to do that: the "#" sign is the code tag, so highlight the output of the command and then press the # symbol in your post formatting menu. Too much information?)

sudo fdisk -l
sudo gdisk -l /dev/sda
(you might have to install gdisk using Muon Package Manager)

So you need some encryption advice.

... I think maybe you are looking for serious answers to your inquiry ....

Well, sure, but humor, or even whimsey, or perhaps veiled sarcasm, is never objected to by ME. And your suggestion actually appeals to me. So, now I'm trying to figure out how to do the following:

I have a desktop with Windows Vista and KB 14.10 dual booted. I'd ditch Windows in a heart beat...and probably should...if I was sure of never ever again needing it. But in any case, I'm looking for how to do this:

1. Add an installation of 15.04 to the hard drive.
2. Encrypt my exiting /home partition and 15.04 (never mind why - I have secrets - perpetual motion is going to BIG in the coming years, trust me!).
3. Then be able to boot into either of the three (er...any of the which? both of the twain..?) at a whim.

I should think this is possible, but I'm not sure where to find the instructions. I'm looking about, but lack of time so far has constrained me from finding instructions I trust.

Any thoughts? Anyone?

[Qqmike]

... I think maybe you are looking for serious answers to your inquiry ....

[Qqmike]

Yeah, you're right, tomcloyd, you don't know the game . I've got 14.04 LTS installed as my OS. For fun, on the same HDD, I installed 15.04, too, as an experiment. And, properly, now and then, I boot into 15.04 and, for awhile, ... I experiment! Then back to 14.04 to get my work done ...

[tomcloyd]

Just a general question, for those who know the culture far better than I do.

I have 15.04 installed on my laptop. I have also noted a serious system tray problem, and posted about it in this forum: the Dropbox icon won't show; I've heard that the Skype icon only just recently started showing up; I know other programs have this problem (for me, Synergy is a big one).

I also note that 15.04 was released in mid-April, over two months ago. In four more months we'll have 15.10 out. The system tray's still a mess. Whatever the problem is with the system tray, it was hardly made known to any of us prior to upgrade, and in those cases where it's a showstopper, having to regress to a previous installation means (so far as I know) a full reinstall, which in my case then entails about two days of work to get my normal working environment back in place.

All this because 15.04 was released with what looks to me like a major glitch.

Am I the only one who uses Dropbox and Skype? Ha.

My question: what's going on upstairs, that this sort of gotcha is considered perfectly acceptable? I really don't get it. Educate me, PLEASE.

Thanks.
