Internet Connectivity / Broadband speed checkers
« on: May 17, 2019, 11:34:13 pm »
Upgraded our broadband recently, and pretty happy with the results - especially as it got BT out of the equation and costs less than the previous, much slower, deal.

However, I've tried multiple broadband speed checkers and get wildly differing results - from 6mbs to 65mbs. Just wondering whether anyone has any clues..

I'm thinking of creating a large file I can upload and download at will with one eye on the clock. I know someone is offering me 5gb of free cloud space, but I can't remember who. I'd never entrust my real data to the cloud, but a big folder of meaningless test data is a different proposition.

General Help & Advice / Virtualbox machines failing to start [Solved]
« on: March 19, 2019, 08:38:39 pm »
My working installation of Virtualbox has just stopped working. I haven't made any changes, so I assume a recent update broke it.

The error is as follows.
Failed to open a session for the virtual machine Windows XP.

The virtual machine 'Windows XP' has terminated unexpectedly during startup with exit code 1 (0x1).

Result Code: NS_ERROR_FAILURE (0x80004005)

Followed by..

I've tried running vboxconfig, but that failed as follows,

Any suggestions much appreciated. Virtualbox keeps telling me a new version is avaiable but so far I haven't upgraded. I'm now thinking that might fix this problem..

General Discussion / Email hacked?
« on: February 18, 2019, 09:35:36 pm »
Just been locked out of my account because of 'unusual activity'.

Having got back in, I found the following.

Time (GMT)                                  Session Type                                                Approximate location
 12/02/2019 19:58                        Automatic Sync                                             United Kingdom

ProtocolIMAP                              Time12/02/2019 19:58
IP:                        Approximate location: United Kingdom

Account alias:                              Type: Unusual activity detected

Trouble is, how do I tell whether it was my phone trying to sync with outlook, or someone else up to no good? An IP lookup suggests that  is in Brighton, Barking or Cardiff, whereas I'm in Norfolk and my ISP is in Scotland, so it looks suspect to my eagle eye.

Also, it appears I sent two messages both to recipients I don't know, but with a subject line referring to a social group I do know. That suggests to me that maybe one of that group got hacked and was used to send fake messages, including to me. Does that sound credible?

Finally, my phone stopped syncing with my outlook account. I haven't set it up again yet because I'm not confident about what's going on.

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.


General Help & Advice / Truecrypt.Is it safe? [solved]
« on: December 06, 2018, 09:03:47 pm »
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?

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*
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][/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][/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:
here's a direct download llink for the current version (4.3.14):
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.



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

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

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

The following information may help to resolve the situation:

                  Recommends: libsdl-ttf2.0-0 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I tried the following, but no luck..
mike@xubuntu:~$ sudo apt-get install libvpx1
[sudo] password for mike:

Package libvpx1 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or

E: Package 'libvpx1' has no installation candidate

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


General Help & Advice / Locked out of my xubuntu install(s) [Solved]
« on: October 22, 2018, 08:59:40 pm »
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!

General Help & Advice / Running defragfs
« on: October 13, 2018, 11:59:37 pm »
Hello Folks,

I've been trying to run defragfs with no success.

Basically, I downloaded it from sourceforge, unpacked it in filemanager, then copied defragfs to usr/bin in a terminal. When I try to run it (using sudo defragfs...) I get "command not found". Ls shows that defragfs does exist in usr/bin, although it's greyed out, so I'm assuming it's not properly unpacked. I tried "make defragfs" in the terminal but got "make: Nothing to be done for 'defragfs'".

Any suggestions welcome. Thanks.

Security / [solved] S3.amazonaws virus?
« on: September 07, 2018, 10:39:28 pm »
I was searching in Firefox for a legitimate copy/stream of the film 'Mahogany', and suddenly S3.amazonaws is my new best friend/browser hijacker.

It's asking me to install an "important Firefox update". Obviously it's scumware. I daren't click 'Don't allow',so I have no option but to shut down Firefox (I'm typing this in Chrome). When I re-open FF it's still there, surprise surprise.

Any ideas folks?

I'm running Xubuntu.


Ubuntu / Corrupted file or directory [solved]
« on: April 29, 2018, 10:28:20 pm »
Hello folks,

As some of you will know, I have an old XP box which I keep for older software etc, but which isn't connected to the internet anymore.

Recently I've been saving files to an external drive which is encrypted using Truecrypt.

Yesterday, Windows froze whilst accessing that drive, and now freezes every time I re-try, with the message "L is not accessible. The file or directory is corrupted and unreadable".

Xubuntu accesses the drive via Truecrypt with no problem, except that the folder I was using in XP now appears empty. I was thinking of using Gparted to attempt data recovery or create a partition table. However, messing about with partition tables is way above my pay grade and feels like a recipe for disaster..

Any suggestions please?


Android devices / Can't copy to Android phone [solved]
« on: February 14, 2018, 10:21:13 pm »
I'm not sure whether I'm in the right place for this question, or whether the problem lies with my installation of Xubuntu, but here goes.

I'm trying to copy an album ripped from a cd (by Soundjuicer) onto the expansion card in my phone. I've done this before with no problem. Today however, nothing gets copied and I get the message "libmtp error. Could not send object. Do you want to skip it? Then File manager seizes up and either I get the "This window is not responding..." message, or I use xkill. Then I have to reboot to get File manager working again.

Any help much appreciated. Thanks.


Ubuntu / Can't change swappiness (Solved)
« on: January 11, 2018, 11:56:17 pm »
Just been trying to change swappiness in Xubuntu.

First, I got a message that gedit was not installed, so I followed the recommendation to install it.
That seemed to go ok, but when I tried to edit sysctl.conf the problems started. Despite error messages, sysctl.conf was presented in a different window and I was able to edit and save it, but when I re-run cat /proc/sys/vm/swappiness, the edit has not affected swappiness (ie: it's still set to 60, not 10)

Any ideas please? Thanks in advance.

General Help & Advice / Triple-boot problem [solved]
« on: November 05, 2017, 10:50:35 pm »
We have a box running Xubuntu 16.04, Ubuntu 14.04 and Windows XP as a triple boot.

Xubuntu is backed up via Redo Backup, and XP via Norton Ghost, both to the same external drive.

Yesterday I tried to do a ghost restore to the XP partition and it failed. I now have an un-bootable XP which equates to a wasted 50gb of disc space.

I'm willing to forget XP, but I'd like to tidy up and reclaim the space. However, Linux can no longer mount that partition, suggesting instead that I run 'fdisk /f' in Windows. I can't get into Windows anymore, but even if I could, it occurs to me that I'm in danger of wrecking my access to Ubuntu/Xubuntu.

It seems to me that multi-boot scenarios are fine until one of the operating systems needs reinstalling, then all bets are off. I think I'm going to give them up. Or am I missing something?

Meanwhile, can anyone suggest a way to reclaim the disk space and retain Xubuntu and hopefully also Ubuntu?
