[SOLVED] Installing package from repository

My objective is to install bluez package for ARM architecture.

These are some steps I have took so far:

Identify bluez source in repository pi@pi:~ $ apt-cache policy bluez bluez: Installed: 5.43-2+rpt2+deb9u2 Candidate: 5.43-2+rpt2+deb9u2 Version table: *** 5.43-2+rpt2+deb9u2 500 500 http://archive.raspberrypi.org/debian stretch/main armhf Packages 100 /var/lib/dpkg/status 5.43-2+deb9u1+b5 500 500 http://raspbian.raspberrypi.org/raspbian stretch/main armhf Packages pi@pi:~ $

The above tells me that "bluez" was installed from two different repositories.

1. I do not understand what the "500" "100" is telling me.
2. Where is the package name ? All I get is "version"

I did try this, but did not expect success:

Wget connected to specified (?) repository, but did not find , as expected , the required package.

Since it failed I did not bother to check the contents of /TEMP_BLUEZ/raspbian.2

Any suggestion how to make the Wget call successful in downloading the ARM version of "bluez" would be greatly appreciated.

Your machine is actually ARM architecture isn't it ? Because if it isn't, then the "bluez" package won't work on a different architecture.

The above tells me that "bluez" was installed from two different repositories.

I don't think it is actually. I think it's telling you what's available.

$ sudo wget -P /TEMP_BLUEZ http://raspbian.raspberrypi.org/raspbian stretch/main armhf Packages 5.43-2+rpt2+deb9u2

The spaces are causing wget to treat each word as a seperate URL. The errors are very clear about that.

That is immaterial for this post - all I need is to be able to retrieve the package for now. I don't think it is actually. I think it's telling you what's available.

Not according to apt - the command used shows what is / was installed and from where.
The "error" is - it does not identify the package name - just version.
I need to go back to apt man to see if it has an option to identify the package name.

Come to think of it - the best approach would be to be able to read just the repository packages tree.
I have managed to retrieve the entire contents of "Packages" ( plain text) - but it is unmanageable , way too big.

I'll try this next
purge bluez
install bluez

The "install " give the repository link where the package was installed from

then I can try another Wget using that repository

sorry I missed scasey post


Got to run Later

I think you need to learn to read manual pages and/or learn how to Google things properly, because you don't seem to have a very good grasp on what you're doing/trying to do. And you've included part of your reply in the quote of what I posted before.

You have not even said which Linux distribution you're using...

Looks like distribution / version is rasbpian stretch

From the apt_preferences man page

priority 100 to the version that is already installed (if any) and to the versions coming from archives which in their Release files are marked as "NotAutomatic: yes" and "ButAutomaticUpgrades: yes" like the Debian backports archive since squeeze-backports. priority 500 to the versions that are not installed and do not belong to the target release.

Another command to see what is installed.

sudo dpkg -l bluez

Thanks , this may lead to the solution.

I can use option "-i" in wget command to retrieve multiple packages, but I need only one anyway.
However, I am still unable to figure out the correct syntax to "wget" bluez package from repository.

Obviously "5.43-2+rpt2+deb9u2" is not correct, neither is "bluez-5.43-2+rpt2+deb9u2".
I'll keep guessing for now, unless there is away to retieve the name from the repository.
Thanks
Appreciate the reply.

Why use wget versus the package manager utilities i.e apt or apt-get?

sudo apt-cache search bluez will find all packages that contain the word bluez.

sudo apt-get install bluez will install bluez packages.

From man wget:

GNU Wget is a free utility for non-interactive download of files from the Web.

It doesn't "retrieve packages", it downloads files.
Arguments to wget are in the form of URLs
As you can see by the errors you got, it adds http:// to a string if it's not there, but the argument should contain, at a minimum, a complete, valid domain name.

Yes, a file being downloaded could contain a package, but you should be using your package manager (apt, yum, etc.) to install packages, not wget.

[I had to pause to answer the phone, so didn't see michaelk's post...]

Yet another attempt to identify the package name required by wget:

pi@pi:~ $ sudo wget -P /TEMP_BLUEZ -i http://raspbian.raspberrypi.org/rasp...armhf/Packages bluez

I am assuming this info was retrieved during the actaull APt install bluez " FROM repository.

FFS - use code boxes for code, not 'quote'.

The 500/100 is the priority - basically, highest wins - see man apt.

I cannot use apt-get because it does not recognize "-a=architecture " option.

This is a hack - I am doing this as an interim step so I can get the "bluez" package for ARM architecture running wget from X86 architecture.

It is imperative that I can specify the package name in wget - which so far is eluding me.

The repository is "architecture sensitive" and that is all I care for now.


Addendum
wget is the correct way to accomplish the task, the PROBLEM is that wget processes FILE(s) and "bluez" is PACKAGE NAME , not a file.

Not sure why you feel a need to yell...

The current package can be found at http://www.bluez.org/download/packag...ez-5.50.tar.xz

You really need to work on your web searching skills, has been repeatedly pointed out to you.
I entered bluez into a search engine. www.bluez.org is the first non-ad link.

Or, maybe, this is what you want
