I'm using Ubuntu 20.04 server edition.

When I run

sudo apt install aptitude

I get the below prompts

Configuration file '/etc/systemd/resolved.conf'
 ==> Modified (by you or by a script) since installation.
 ==> Package distributor has shipped an updated version.
   What would you like to do about it ?  Your options are:
    Y or I  : install the package maintainer's version
    N or O  : keep your currently-installed version
      D     : show the differences between the versions
      Z     : start a shell to examine the situation
 The default action is to keep your current version.

Can I avoid all the prompts and just default to package maintainer's version without being asked?

I will get two kinds of prompts. The command line one as you see above, and the one with slightly more GUI with the pink background asking similar question.

I just want to install with just the package maintainer's version regardless.

I was following iRedmail documentation and came across this line

iRedMail needs official Debian/Ubuntu apt repositories, please enable them in /etc/apt/sources.list.

How do I go about checking if this is true?

I am using 16.04 headless server edition

I got this on a fresh installation of Ubuntu 16.04 on AWS Lightsail

Then I follow the instructions

Then I tried the other one

What should I do now?

Server is 14.04

My timedatectl status

When I run ntpq I get connection refused. I have googled around but none of the solution works for me.

This is my /etc/ntp.conf

I created a file that is in UTF-8 encoding. This file contains chinese characters.

When I sftp the file from my macbook into the ubuntu 14.04 server headless, the Chinese characters become diamond shape.

When I look at the file (either via SSH or directly on the machine itself using a CRT monitor), the file always appears as diamond shaped.

The language locale of the ubuntu is en_US.UTF-8

How do I

a) either somehow retype the characters inside the ubuntu headless 14.04?

Or

b) transfer the file over and still have the chinese characters rendered correctly?

UPDATE

I mean I have no GUI on the 14.04 ubuntu server edition. The files whenever I open using vim or nano or whatever editor keep showing up the chinese characters as diamond shape things.

I have checked my installed kernels

I have the following Upstart script saved as /etc/init/automount.conf:

description     "SOME DESCRIPTION"

start on startup

task
exec mount -t vboxsf WebApps -o rw,dmode=777,gid=GROUP_ID,uid=USER_ID /var/virtual/some_folder_name

where GROUP_ID and USER_ID is some number I took from /etc/passwd

Previously before I upgraded my ubuntu from 12.10 to 14.04, this was working. After I upgraded it, I also upgraded the virtual box from 4.3.8 to 4.3.10. Subsequently, I think there was an issue with 4.3.10. So I downgraded the virtual box back to 4.3.8.

Now everything is working with the shared folders. Unfortunately, this script is not executed, I believe. The reason is because, the mount is not happening on start up.

I can still execute the command without any problem whatsoever. Why isn't Upstart able to run this any more? How can I tell what the problem is?

Running 14.04 in virtualbox 4.3.8

Unable to detect the guest additions.iso when i selected the guest additions.iso in the IDE Secondary Master.

No problem, so I used wget and downloaded the iso into the guest ubuntu headless.

when I attempt to load the iso from inside using these commands:

sudo mkdir /media/iso
sudo modprobe loop
sudo mount filename.iso /media/iso -t iso9660 -o loop

At the sudo modprobe loop, I got the following error:

modprobe: ERROR: ../libkmod/libkmod.c:556 kmod_search_moddep() could not open moddep file '/lib/modules/3.13.0-24-generic/modules.dep.bin'

Here are my lsb_release -a:

I have set up a 12.04 LTS ubuntu headless server 64 bit.

This is my network interfaces

I can do ping www.google.com from inside the server. However, I am unable to access https repositories when I try to use composer.

I know the proxy server allows me to use all protocols via www.xxxx.com:8080

Please advise.

I have a CakePHP web app running on a ubuntu 12.04 LTS server. The server is hosted on a machine within a intranet of a corporation.

The web app needs to send out transactional emails a few times a day.

According to SendGrid, emails are largely divided into 2 types: marketing and transactional.

Transactional emails are those that notify you something has happened/ is about to happen.

Recipients of this email are usually advised not to reply back.

Because this web app I am doing is mainly for internal usage and therefore the emails sent to internal corporate users, I do not envisage the need to set up SPF for emails and so on.

However, I am not sure how to install an email server in ubuntu 12.04 that will work with my CakePHP web app.

I do know that my web app works with GMAIL SMTP settings.

All I need to do is to use the following in my CakePHP email settings:

public $gmail = array(
        'host' => 'ssl://smtp.gmail.com',
        'port' => 465,
        'username' => '[email protected]',
        'password' => 'secret_password',
        'transport' => 'Smtp'
    );

I believe I can use postfix, but I have never installed it before. Need advice on exactly what steps I need to undertake to achieve the above.

Off the top of my head I think I at least need to know:

• how to install email server
• configuration for the email server
• how to create an account on the email server (e.g. noreply@IP_ADDRESS?? )
• SMTP configuration for my web app to send out the email

Both the web app and the email server are on the same machine.

Another key point to add is that the machine has no direct access to the internet. It is purely on the corporate intranet.

I typed apt-get update and then I saw a long list of

EDAC i7Core: Lost 127 memory errors

Please help me understand what has happened.

I am using ubuntu server edition 12.04 LTS

UPDATE:

I followed Gilles answer. I got the following when I do a dmesg

I am installing ubuntu 12.04 onto a HP 1U rack server that is in a lab with no internet connection.

I need to install PHP, Nginx and other packages so that I can run my web app on it that will serve internal clients.

I tried to run apt-offline set /media/usb/updates.sig but the server prompts me to install apt-offline instead.

What should I do to install the packages I want and keep the server up to date if it is not connected to the internet?

I need to call a perl script from my php file.

I attempted to install the PECL extension for Perl.

I was unsuccessful.

I tried the following:

I have just created a fresh installation of Ubuntu 12.10

I have created a www-data user account.

When I switch to www-data, I cannot see www-data at the front of the prompt.

1. What is the technical name to call that part of the prompt?
2. How can I make it appear for www-data?

See this for reference.

As you can see, root has this. But not www-data

My memory usage was a 4% after a fresh ubuntu 12.10 installation

after i install php packages etc using this gist, https://gist.github.com/4372049

my memory usage now reached 41%.

should i be concerned?

if not, then at what memory usage level should i be concerned?

if yes, then what remedies should I do?

UPDATE:

based on suggestion to post my top followed by >

I need to use Windows 7 VM to test my web application in Internet Explorer.

I have a bootable USB drive for Windows 7.

I have already installed VirtualBox.

However in the vbox when I press start, the first run wizard is looking for a DVD image, which I do not have.

What can I do?

I need help.

My portable hdd can be plugged into my new ASUS N43J laptop in WINDOWS 7 from any of the 3 USB ports.

In Ubuntu, it only works with 1 port.

using 10.04 64bit.

Please advise.

Edit:

I just realised that the port is usb3.0. Sorry for my ignorance. HOw do i get my Western Digital hdd to work in usb 3.0 for ubuntu 10.04 64 bit?
