I am trying to set up a stable repository and getting an error —
need a single repository as an argument
Can someone please tell me what is wrong with this statement:
sudo add-apt-repository deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable

I think you are after this, actually:
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
The quotes make the entire string you were trying to add be treated as a single argument. This way you don’t need to mess with escaping spaces (which your command didn’t actually do properly which is why it all failed and gave you errors).
Note that you will still need to download the GPG key in use for the repository, as add-apt-repository is incapable of doing that for straight strings like you’re adding here.

Question about ‘add-apt-repository’ command
Here is a simple question about the «add-apt-repository» command.
So I was trying to install Oracle’s VirtualBox the correct way and when tried to add repositories for the software, I suddenly ran into questions; for example the official site says to add the line ‘deb http://download.virtualbox.org/virtualbox/debian trusty contrib‘ into the «/etc/apt/sources.list» file. Why can’t I do this via terminal? Or what is the correct command for this? I successfully managed to add the line via GUI or Nano’ing the «sources.list» file, but not via terminal. It’s kind of confusing since most of other repository entries I have on my machine has instead a «ppa:» naming scheme, not «http://xxx.xxx.xxx» etc.

Re: Question about ‘add-apt-repository’ command
Did you try using add-apt-repository? There is a man (manual) page for this command as there is for all commands.
Code:
man add-apt-repository
add-apt-repository is a script which adds an external APT repository to either /etc/apt/sources.list or a file in /etc/apt/sources.list.d/ or removes an already existing repository.

Yes I did use «add-apt-repository man. As I said it’s not working for the line in question.

Re: Question about ‘add-apt-repository’ command
add-apt-repository can be used for traditional ‘deb address section’ repositories, almost as-is.
For instance, I prefer using the latest official builds of mkvtoolnix instead of the ones in the Ubuntu repositories. The info is given as the traditional ‘add this to your sources.list’ as:
(for 15.10):Code:
deb http://mkvtoolnix.download/ubuntu/wily/ ./ deb-src http://mkvtoolnix.download/ubuntu/wily/ ./
But I’d prefer to do it with add-apt-repository so I don’t have to worry about opening a text editor.
Code:
sudo add-apt-repository "deb http://mkvtoolnix.download/ubuntu/wily/ ./" wget -q -O - https://mkvtoolnix.download/gpg-pub-moritzbunkus.txt | sudo apt-key add -
(that second one is just importing the signing keys; not all repos will require that kind of thing)
You have to remember to enclose the entire deb line in double-quotes as the argument to add-apt-repository.

Thanks, it worked! Now let me try and understand why.
So basically what is a «PPA» and why do I need to include the symmetric double quotes if the line to be added does not come with PPA? What is the difference between a «PPA» and a «non-PPA» repository address? Also, what is the difference between adding or not that second line «deb-src» from your example? Is that the repository address for the source code or something?

Technically, any external repository is a ‘PPA’. All ‘PPA’ stands for is ‘Personal Package Archive’…i.e., a plain old repository. The double quotes are needed because there are space characters in the information, and the double-quotes let add-apt-repository see it as a single item rather than three or more (the word deb, the address, and one or more sections). The ppa: protocol used on Launchpad doesn’t contain spaces, so it can be interpreted as a single item regardless of double-quotes.
The reason that you can go on Launchpad, look up PPAs, and use the ppa: protocol to add them via add-apt-repository is because it translates Launchpad’s ppa: address data into the right lines/configuration files to add to the sources.list (or said another way, if you use ‘ppa:’ it knows to go to Launchpad and grab the data from that shorthand). There’s nothing all that special about it, except that Launchpad is a centralized hosting service and the ppa: protocol they provide also imports the authentication keys along with the rest of the repo data. If you notice, Launchpad provides a traditional ‘copy this to your sources.list and use this GPG key to authenticate it’ information box in the write-up for each PPA, so you could do it manually if you wanted.
And yes, the deb-src repo is a repository for the source code of the packages in the deb repo.

Цитата: dmitry1903 от 16 марта 2018, 20:27:16Если нужен пакет, которого нет в дебиановском репозитории, будет ли безопаснее скачать этот пакет и установить вручную, а не добавлять посторонний репозиторий?
Для одного пакета репозиторий создают только тогда когда предполагают частые обновления. Например браузеры с закрытым кодом. Кто их использует и по долгу сидит на одном выпуске debian прекрасно знают что рано или поздно для этого репозитория зависимости ломаются ( порядка 2х с небольшим лет). Другой случай вроде wine, пакет тянет за собой дополнительные зависимости из этого стороннего репозитория. Для целостности пакетной базы это практически всегда плохо. Поставив однажды свежий wine из стороннего источника через какое то время можно получить проблемы с обновлением системы или невозможность установки некоторых родных пакетов. Бывает что всё обходится без последствий но гарантия слетает.

I want to install opencv in ubuntu 17.04 and I know that the jasper library is removed from ubuntu 17.04
what should I do to complete install opencv correctly ???
I tried used this two below command that showed here but it does not work
sudo apt-get install opencv-data
sudo apt-get install libopencv-dev

Use these commands:
sudo add-apt-repository 'deb http://security.ubuntu.com/ubuntu xenial-security main'
sudo apt update
sudo apt install libjasper1 libjasper-dev
This worked on my Ubuntu 18.04 after I replaced the double-quotes with single quotes. With the double quotes I was getting this error:

Under Ubuntu18.04, if you directly add-apt-repository will encounter another GPG error.
$ sudo add-apt-repository "deb http://security.ubuntu.com/ubuntu xenial-security main"
W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://dl.yarnpkg.com/debian stable InRelease: The following signatures were invalid: ...EXPKEYSIGhttps://dl.yarnpkg.com/debian/dists/stable/InRelease The following signatures were invalid: EXPKEYSIG ...
You have to update the key
sudo apt-key adv --refresh-keys --keyserver keyserver.ubuntu.com
Then you are now safe to install libjasper-dev.
sudo apt-get install libjasper-dev

To build the latest version of libjasper as package for Ubuntu do the following:
Download the Jasper source code from here: https://github.com/jasper-software/jasper/tree/version-2.0.25
Run the following script:
#!/bin/bash
VERSION=2.0.25
unzip jasper-version-$VERSION.zip
cd jasper-version-$VERSION
mkdir compile
SOURCE_DIR=`pwd`
BUILD_DIR=compile
INSTALL_DIR=/usr
OPTIONS=
cmake -G "Unix Makefiles" -H$SOURCE_DIR -B$BUILD_DIR -DCMAKE_INSTALL_PREFIX=$INSTALL_DIR $OPTIONS
cd compile
make clean all
cat >description-pak <<EOF
JasPer Image Processing/Coding Tool Kit
EOF
fakeroot checkinstall --fstrans --install=no --pkgname=libjasper --pkgversion=$VERSION --pkgrelease 1 --pkglicense="JasPer 2.0"
bash -c "make install" </dev/null
mv libjasper_$VERSION-1_amd64.deb ../..
cd ../..
rm -rf jasper-version-$VERSION
Result is a Debian package that can be installed using dpkg or apt.

This Solution was tested on mendel(debian) with arm64 architecture. If this works for Ubuntu is not clear.
Open terminal and run the following commands:
cd /etc/apt/sources.list.d
sudo nano multistrap-main.list
Add there these two lines:
deb http://ports.ubuntu.com/ubuntu-ports xenial-security main
deb http://ports.ubuntu.com/ubuntu-ports impish main
save and exit. Then run:
sudo apt update
If there is a key missing use the following and run again update:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys <key>
Then install jasper:
sudo apt-get install libjasper-dev
Finally remove or comment out the added repositories from multistrap-main.list.

problem adding a repository
Trying to add a repository using add-apt-repository and get an error message
Here is the output:
ohn@john-K52Jc:~$ sudo add-apt-repository http://ppa.launchpad.net/opencpn/opencpn/ubuntu raring

Where is my syntax wrong?
Question information
Raring is EOL and no longer supported in any way. It is EOL. I suggest you wipe Raring off the system and do a clean install of Trusty which is LTS and supported til April 2019.
You can add a PPA with:
sudo add-apt-repository ppa:opencpn/opencpn
You need the bold PPA link from the PPA page.
Thanks
Thanks for your help
I upgraded to Trusty when it was released.
Still having the error message about requiring a single repository when I used the OpenCPN commands.
With your command this is what happended:

How do I install OpenCPN from here?
Again there seems to be a missing library. You could try to install it by running «sudo apt-get install libwxgtk2.8-0», but probably there are more missing libraries.
After adding the repository, did you install OpenCPN running «sudo apt-get install opencpn»? Normaly this should install all necessary libraries too.
I did a little research and just realized that there is no package for Ubuntu 14.04 Trusty in the repository.
Thus, you should install OpenCPN via the .deb package available on
http://opencpn.org/ocpn/download
Also have a look at
http://opencpn.org/ocpn/installing_opencpn
under the Linux paragraph there are detailed instructions on how to install it, and even on how to install the needed dependencies(!).
If you already installed OpenCPN in some way, but are only missing the dependencies (as running «opencpn» gives you an output), just run the commands given on the OpenCPN Installation site:
«sudo gdebi <downloaded_opencpn_file.deb>» (if you installed a .deb package)
or
«sudo apt-get install libwxgtk2.8-0 libwxbase2.8-0 wx-common libglu1-mesa libgl1-mesa-glx zlib1g bzip2 gpsd gpsd-clients xcalib xdg-utils libportaudio2 libkml0 libtinyxml2.6.2 liburiparser1 zlib1g libexpat1»
Also you may want to remove the ppa from your sources list, as it will only give errors when you update.
For this run «sudo add-apt-repository —remove ppa:opencpn/opencpn»
I hope this will help!

I don’t think I installed all of the repository for when I run sudo add-apt-repository here is the output:
john@john-K52Jc:~$ sudo add-apt-repository http://ppa.launchpad.net/opencpn/opencpn/ubuntu trusty main
Error: need a single repository as argument
How do I get a single repository as argument?
You were trying the wrong PPA.
Please run these Terminal commands instead:
sudo add-apt-repository ppa:nohal/opencpn
sudo apt-get update
sudo apt-get install opencpn
I expect that the commands given by Mark will help.
I just want to add some background information that might shed some light on what was going wrong here:
1. The command add-apt-repository needs just one single argument, either in the form ppa:user/ppa-name or in the form «http://sourceserver/directory/ubuntu release bucket» WITH QUOTES AROUND. This makes it «a single repository». (See my comment in response #4)
2. Just adding a repository server with the add-apt-repository command is not enough. This only adds the server to the list of repositories, but does not download anything yet. You need to execute «sudo apt-get update» (or use the reload button in software-center or synaptic) to pull in the information about the repository’s contents. Only after doing that, the commands to install or upgrade software will also look in that repository.
3. You seem to have mixed the commands to build and install opencpn from source with attempts to install pre-built packages from Ubuntu repositories. This might fail (and apparently has failed with «error while loading shared libraries»).
If you stick to .dev packages installed with apt-get commands or via software-center or synaptic or gdebi, then the dependencies will be automatically be taken care of.
If you try downloading the source and building the executable yourself, then you have to make sure by yourself, that all dependencies are satisfied (e.g. see the instructions in the link to opencpn.org given by Miguel).
4. I found two PPAs on Launchpad with opencpn software https://launchpad.net/ubuntu/+ppas?name_filter=opencpn The second one (ppa:opencpn/opencpn) has that software only for the Ubuntu releases up to raring. The first one (ppa:nohal/opencpn) has also software for trusty. So you should remove the opencpn one and add nohal one with the commands already given by Miguel and Mark.
And another thing:
The output
0 upgraded, 1 newly installed, 0 to remove and 14 not upgraded
of the apt-get install command shows that not all packages on your system are fully up-to-date.
You should either issue the commands
sudo apt-getupdate
sudo apt-get upgrade
or start update-manager to upgrade all your packages to the latest version.
Thank you so much for your help.
With Mark’s commands in response #9 I am able to do a clean installation on my desktop and the new version of OpenCPN looks different to what I am stuck with on my laptop where my boat languishes where it was two years ago.
What I think I need to do now is a complete removal of all versions of OpenCPN but it does not show up on Synaptic and removing it with the Ubuntu Software centre is not effective enough
What do you suggest?
What is the output of :
lsb_release -a; uname -a; apt-cache policy opencpn
