Is there a way to install a deb package directly from a URL, using a shell? Something like

dpkg -i http://domain.com/path/to/package.deb

(I know I could use wget and then dpkg, I'm just wondering if there's something that does it already)

Edit: I didn't see your previous statement about knowing you could wget so this is a bit awkward... I'll leave this here for anybody who wants to know how to do this. Additionally the previous version of my answer didn't work but this version (at the expense of being somewhat longer) does:

URL='http://path.to/my.deb'; FILE=`mktemp`; wget "$URL" -qO $FILE && sudo dpkg -i $FILE; rm $FILE

You just need to alter the URL at the beginning. This could be aliased or written as a bash function.

I realise there are technical and security issues surrounding this (you don't get automatic updates, can the source be trusted, etc), but on a purely can-I-do-it basis, this might work.

The quickest method is like this. Click to start installing shutter Install shutter.

URLs used for clicking on the name:

http://packages.ubuntu.com/shutter

... and for the click on the icon:

http://apt.ubuntu.com/p/shutter

And yes you need Ubuntu Software center to finish the installation of a .DEB. Otherwise you will have to execute the installation from Nautilus or command line.

Complete text used for this is for AskUbuntu only so you need to reformat this into an anchor:

[shutter](http://packages.ubuntu.com/shutter) [![Install shutter]
(http://bit.ly/software-small)](http://apt.ubuntu.com/p/shutter)

More info can be found on the apturl wiki page:

  1. 1 Package:

    a href="apt:package"

  2. Bundling several packages:

    a href="apt:package1,package2,package3"

  3. Enabling repositories:

    apturl apt:freevial?section=universe

So if the software is not in a default enabled repository you should add a 'section=' to it. Otherwise you can not use this method and need the user to download it and install themself.

Just a note: AptUrl doesn't work for software that's not on the users repository –  sergio91pt Jul 5 '11 at 11:11

That's nice, thanks! Anyway I'm looking for something that would work from the command line, I edited the question. Sadly apturl expects a running X :/ –  Joril Jul 6 '11 at 9:12

Normally you would do this like

wget --quiet --output-document=- http://example.com/path/to/package.deb | dpkg --install -

or maybe

dpkg --install <(wget --quiet --output-document=- http://example.com/path/to/package.deb)

but dpkg uses mmap to access the file so neither works (you have to manually create and remove a temporary file). There is a bug report about this: #367297

I actually have a script that does something similar:

Just copy and paste this script into ~/bin (create this folder if it doesn't exist):

#!/bin/bash
# ~/bin/dpkg
COUNT=0
for i in $@; do
        echo $i | grep http 2>&1 > /dev/null
        if [ $? == 0 ]; then
                URL="$URL $i"
                continue
        fi
        PASSTODPKG="$PASSTODPKG $i"
done

#Remove beginning and trailing space
URL=$(echo $URL | sed -e 's/^ //g' -e 's/ $//g')

if [ ! -z $URL ]; then
        mkdir /tmp/debs
        cd /tmp/debs
        for i in $URL; do
                wget "$i"
        done
        dpkg $PASSTODPKG /tmp/debs/*.deb
else
        dpkg $PASSTODPKG
fi

Then add this to the last line in ~/.bashrc

PATH="~/bin:$PATH"

The script is just a wrapper for dpkg. The line in the ~/.bashrc file tells bash that whenever you type dpkg, it will run ~/bin/dpkg (the script), rather than /usr/bin/dpkg.

The script will just pass the arguments to dpkg if there's no URL's given. The script also supports multiple URL's. Here are some examples that will work:

sudo dpkg -i http://www.example.com/file1.deb
sudo dpkg -i http://www.example.com/file1.deb http://www.example.com/file2.deb
sudo dpkg -i http://www.example.com/file1.deb existing.deb http://www.example.com/file2.deb
sudo dpkg -i existing.deb

Please let me know if there are any problems with the script. I not at my Ubuntu computer, so I wrote this off of my memory. –  Xiao-Long Chen Jul 5 '11 at 21:46
    
What a memory ! –  enzotib Jul 6 '11 at 15:27
    
@enzotib: haha! With the amount of reinstalls I do, my memory is more useful than my backups :) –  Xiao-Long Chen Jul 6 '11 at 15:34

You can append it to /etc/bash.bashrc as follows (it's an upgrade from Chen's script):

'dpkg-url'() {

COUNT=0

for package in "${urls[@]}"; do
    if [[ $package = *http* ]]; then 
    urls+=("$package")
    fi

    dpkg_url="$dpkg_url "$package""
done

# Remove beginning and trailing spaces #

url=$(echo "$url" | sed -e 's/^ //g' -e 's/ $//g')

if [[ ! -z "$url" ]]; then
    directory=$(mktemp -d);
        trap 'rm -rf "$directory"' EXIT

    cd "$directory" || exit
        for package in "$url"; do
            wget ""$package""
        done
    dpkg $dpkg_url "$directory"/*.deb
else
    dpkg $dpkg_url
fi
}

though i do not see why i get this error when calling it as follows:

dpkg-url -i http://downloads.sourceforge.net/ldview/ldview-4.2-beta1.x64.deb
dpkg: error: need an action option

Type dpkg --help for help about installing and deinstalling packages [*];
Use `dselect' or `aptitude' for user-friendly package management;
Type dpkg -Dhelp for a list of dpkg debug flag values;
Type dpkg --force-help for a list of forcing options;
Type dpkg-deb --help for help about manipulating *.deb files;

Options marked [*] produce a lot of output - pipe it through `less' or `more' !
