Ask the author(s)
Download the source and read it

Seems as if the information you are looking for is rare knowledge.

Please update the forum if you happen to reach a conclusion after reviewing the code. Note that the download link from that webpage contains different architecture based versions of aptitude, arm hard float is included in that list.

I believe just leaving off the "=" sign may work..nothing more 'complex' than a syntax error, but the OP can't seem to grasp that.

Add to that the fact that (if the OP actually added in the repos for ARM), they don't HAVE to specify architecture, just "apt-get install bluez". That was suggested in some of the other (several) threads they have open about this.

@TB0ne,

I wholeheartedly agree that the OP has been given full answers as to what exactly they should try.

Meanwhile they seem to be repeatedly asking for more expert level knowledge about how aptitude works.

My best recommendation is therefore to follow the recommendations I've outlined, however really my "go to" variation on that would be to read the source code. I feel one cannot countermand what actual source code says, and in fact you can build it yourself and test it out, or add debug/features to it to customize it.

They claim very much to know how to read and seem to imply greatly that LQ members are unable to provide sufficient answers. Therefore the links provide contain a great deal of information for them to read, which will clearly answer any and all questions they have about the aptitude package.

Did you try "-a armhf", without the "="???

Which was exactly what they have already been told.

Your post is far from complex, but the answers you've received (here and in the numerous other bluez threads you've started) seem to be too complex. I put "linux apt specify architecture", and found the link posted above. Very first hit, for 681,000 others.

Aman to that.

Once again, exactly what they've been told.

In any case, this OP is the latest addition to my Ignore List.

no it is not the equal sign:

Code:

root@host:~# apt -a=amd64 install zsh
E: Command line option 'a' [from -a=amd64] is not understood in combination with the other options.
root@host:~# apt -a amd64 install zsh
E: Command line option 'a' [from -a] is not understood in combination with the other options.
root@host:~#

here is the source to parse command line: https://github.com/Debian/apt/blob/c...mndline.cc#L90 (line 126 prints the error message)
The message means: The specified [install] subcommand has no such option (-a). Probably the phrasing is unfelicitous.
here is the source to configure the parser: https://github.com/Debian/apt/blob/c...ndline.cc#L176
and you can see where a "host-architecture" is specified at all.

Nevermind...see what you're saying.

I tested it on amd64. but here it is on RPi3, raspbian stretch:

Code:

root@host:~# apt -a=armhf install zsh
E: Command line option 'a' [from -a=armhf] is not understood in combination with the other options.
root@host:~# apt -a armhf install zsh
E: Command line option 'a' [from -a] is not understood in combination with the other options.
root@host:~# apt -a=world install zsh
E: Command line option 'a' [from -a=world] is not understood in combination with the other options.
root@host:~# apt -asomething install zsh
E: Command line option 'a' [from -asomething] is not understood in combination with the other options.
root@host:~# apt -a surprise install zsh
E: Command line option 'a' [from -a] is not understood in combination with the other options.
root@host:~#

apt-get works exactly the same way.

The "apt-get" option -a description / doc is indirectly saying -a is to be used in compile and not in install.
Of course the bluez I am trying to work with is complied.

SOLVED

No, it does not. It is only you who thinks it is implied somehow. see post #8.

In that case please mark the thread solved.

Also if you occasionally want to say thanks just click on yes.

Not to mention the OP already has the package installed...
