General Help & Advice / Re: Help needed with dual booting

Do budgies really like chocolate? Who knew?

Personally I've given up dual-booting. Too much trouble when one half goes wrong...

OK. I got fed up and shut down the PC.

On restart I was able to access the encrypted drive...

Marking this solved now.

General Help & Advice / Tumblerd preventing dismount in Truecrypt [solved]
« on: December 30, 2018, 10:18:34 pm »
This is weird. I've just been accessing an encrypted drive, and now I want to unmount it.

However, Truecrypt says "the target is busy". If I try to unmount it in the File Manager I get "Volume is busy" and apparently /usr/lib/x86_64-linux-gnu/tumblr-1/tumblerd is the culprit.

The thing is, I wasn't using Tumblr. In fact I never do.

Truecrypt isn't offering to force a dismount, although the file manager does, but I'm worried about losing access to the encrypted drive, so I don't want to risk that.

Any suggestions gratefully received.

Thanks Wishbone,

I've found a copy of Truecrypt 7.1 and installed it so I'll stick with that for now.

Thanks for your input.

I've used TrueCrypt for years on Windows machines and, more recently, in Linux.

Now I'm trying to install it in Xubuntu, but I can't find the installation file, and everywhere I look on the web is either offering version 7.2 which may be unstable, asking me to use a PPA, or getting blocked by Chrome as a potentially dangerous site.

I know TC isn't officially supported since 2014, but all I'm trying to do is protect my data from anyone who might steal, or otherwise access my PC. I figure those people would probably not be able to crack the last stable version of TC, and probably wouldn't even bother trying, since this is just someone's personal computer and unlikely to contain anything particularly valuable to a casual thief.

Any views, anyone?

Ok. I got vb to recognise one of my vms, so I'm marking this solved now.

Thanks again, SeZo.

Thanks SeZo,

I followed the link, downloaded the Ubuntu 16.04 files, accepted the option to open with the package installer and bingo! I can now open virtualbox 5.2.22.

My next task will be to get it to recognize one or two VMs I created before reinstalling Xubuntu and upgrading to 5.2.22. I'll leave this thread open for the moment since it's the obvious place for any questions I might have on that score.

General Help & Advice / Problems installing virtualbox [solved]
« on: November 16, 2018, 09:00:43 pm »
I'm trying to install virtualbox in a new installation of Xubuntu, by following Mark's advice in a different thread, which I've quoted below (because I don't know how to reference the other thread here).


OK,let's remove any verions of virtualbox that might be installed or partially installed:
Code: [Select]
sudo apt purge virtualbox*
then
Code: [Select]
sudo apt clean

Make sure you have build-essential, linux-headers-generic, and dkms installed:
Code: [Select]
sudo apt install build-essential linux-headers-generic dkms

add the public key for the oracle virtualbox repo with:
Code: [Select]
wget -q [url]http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc[/url] -O- | sudo apt-key add -

Now backup your sources.list:
Code: [Select]
sudo cp -v /etc/apt/sources.list /etc/apt/sources.list.bak

Now open sources.list for editing:
Code: [Select]
sudo gedit /etc/apt/sources.list

and add these 2 NEW LINES at the bottom:
Code: [Select]
###### Oracle VirtualBox repo
deb [url]http://download.virtualbox.org/virtualbox/debian[/url] trusty contrib
SAVE the file and exit gedit.

Back in the terminal update the package cache:
Code: [Select]
sudo apt update

and install virtualbox-4.3 with
Code: [Select]
sudo apt install virtualbox-4.3

Check you're a member of the vboxusers group and add yourself if necessary.

One finished installing (and adding yourself to the vboxusers group if necessary) ..REBOOT.

Download the extensions pack for the correct version of virtualbox from here:
https://www.virtualbox.org/wiki/Downloads
here's a direct download llink for the current version (4.3.14):
http://download.virtualbox.org/virtualbox/4.3.14/Oracle_VM_VirtualBox_Extension_Pack-4.3.14-95030.vbox-extpack
and double click it to to install it .. virtualbox will start and offer to install it, click the "Install" button, then scroll to the bottom of the license and click the "I Agree" button, and enter your password when prompted.

Done.

Everthing works until sudo apt install virtualbox-4.3, which gives the following errors

mike@xubuntu:~$ sudo apt install virtualbox-4.3

I tried the following, but no luck..

mike@xubuntu:~$

Where do I go from here, folks?  This worked in Ubuntu 14.04.

General Help & Advice / Re: Locked out of my xubuntu install(s)

Hello Mark,

You've cracked it again! I'm back into the original installation, having set up the administrator account as you suggested. It worked like a charm. Then I reset the password for my own account and am now able to access that too.

I'd already copied off my data via the command line, which I managed to get to grips with this morning. I'm enjoying the command line. Reminds me of my old DoS days (once an old DoS-er, always an old DoS-er).

When I tried the thunar thing, I still got a 'permission denied' message. That may be something to do with the fact that I used a Lubuntu livecd, so I had to use PCManFS instead of thunar? Seems unlikely, but I can't think of any other reason - except that the whole episode is a bit of a mystery considering it began with me installing Xubuntu on a new SSD with the old hdd disconnected..

Anyway, at least I'm now back to square one, with data intact. And I thought the SSD would save me time, not cost me hours of banging my head on the desk!

The next challenge will be to try to clone the Xubuntu half of a dual-boot onto the SSD... I expect I'll be back quite soon!

Thanks again for your help. Greatly appreciated.

Been struggling half the day with the command line and a live cd to no avail. Damned if I can work out how to copy off the data. I can see it in text mode but I can't find or mount anything to copy it to.

With the live cd I can see the whole hard drive but haven't got permission to access any of the users in the Xubuntu partition.

Will do, Mark.

But first I want to copy all the data off onto an external drive, if possible. I'm looking into that now.

I'll be back...

Hello Mark,

I did get into the guest account. Also there are 2 other user accounts (which never get used). I can't log into them, either in text mode (login incorrect) or normally.

Yes! Mark, you're a genius.

Do normal terminal commands work in text mode? Is there something I can tweak to get back in with the UI? I'm not great with the command line, but I used to be fine with DoS, so I think I'll get by well enough to copy off the files I want..

I'll abbreviate this or it's going to rival war and peace. Bottom line is as follows..

I bought an ssd, unplugged the hdd containing my dual-boot of Ubuntu and Xubuntu, installed the ssd. There followed some fiddling about because the ssd wasn't recognised and suddenly, neither was the sata DVD drive. So I ended up connecting both the ssd and the hdd and playing with the AHCI settings.

I then installed from a Ubuntu minimal install cd (because my PC won't boot from a DVD). I must have missed the option to choose Xubuntu desktop, because I ended up with just the Ubuntu core - no UI. So I ran sudo apt-get install xubuntu-desktop.

Whilst testing the new installation (which turned out to be corrupt - various things not working), I set it not to require a password at boot-up. And that's where it all went very wrong. On the next boot, it didn't go straight to the desktop as I expected. It offered me a dialog with my username, but nowhere to give a password. So I can't get back in. No problem - all I need to do is wipe the ssd and start again, right?

Wrong! because for some reason I can't even begin to understand, when I swap the ssd out and the hdd back in (ie: back to 'normal'), the original installation of Xubuntu, which used to go straight to the desktop, now also asks for a username but no password. If I select the 'other' account and type my username and password it keeps telling me the password is wrong, even though I know it's right!

There's data in the original Home folder I'd really rather not lose. Not critical, hence no backups, but a lot of stuff that's hard to replicate. I expected the old installation to remain untouched, and I can't understand how changes on the ssd have apparently affected the hdd.

Heeelp. Please!

OK Mark, that's fair enough. Thank you.

It's academic anyway, as I'll be replacing the disk with an SSD shortly.

Thanks for your input, as always.
