SCGI package not available for ARM systems

[MikeShiner]

Firstly, thanks for putting this together, looks great.

Currently running Ubuntu Server 20.04 LTS on my Raspberry Pi 4.

Script correctly identifies my system, but the SCGI package it manually installs is hardcoded to AMD arch. I have a quick check on the server, and only AMD and i386 are available.

Do you know of an alternative for ARM based systems?

@MikeShiner Hey I don't have access to RPI4 hardware, so I can't test if it will work, but try swapping link on line 495 to http://ftp.debian.org/debian/pool/main/s/scgi/libapache2-mod-scgi_1.13-1.1_arm64.deb

I doublechecked that RPI4 uses arm64, but ARMs are confusing to me, there are also other versions: armel and armhf -> https://packages.debian.org/buster/libapache2-mod-scgi

But hopefully this arm64 will do. Let me know if that works.

It's line 502 now (recently updated). Look for function INSTALL_SCGI

[NomadicPython]

So, just wanted to add to it that http://mirrors.edge.kernel.org/ubuntu/pool/universe/s/scgi/ has i386.deb as well. so changing that worked for me. (Only after deleting the amd64.deb file from previous attempt)

So that could be a possible change in the script.

@caseybekey hey, thx for info, any chance you could prepare the code and push it? i'll see and accept just please remember to add some kind of check step to verify if we're x86_64 or i386. because by default it assumes 64 bit

thanks!

Can confirm this works for my RPI4 on Ubuntu 22.04, will this be implemented into the script?

thanks for input buddy, i'll try to update this this/next weekend as you can see, i lack free time, but if it works then I trust you and just update code. I have nowhere to run it.

@Whoffie good news and bad news: Good is i just pushed commit Bad is i also rolled it back

It's actually little more complex than I thought. With Raspbian it's easy, because it's only for raspberry, but I'd need another function for Ubuntu/Debian to check if it's ARM or x86 system. In theory I could do it without hardware, but it's like blindfolded surgery.

Until I get my hands on Rpi (or remote hands of someone who's very patient) I won't be risking breaking the script because this needs to be tested well.

So to summarize: for now, manual change of this URL will do, when I'll get Rpi, then we can try to fix it in a proper way.

It's not working on armhf, dude

[Whoffie]

I can’t speak for armhf, Raspberry Pi 4 uses arm64.

@myloginforgithub and @Whoffie i think i got an idea on how to solve the problem (make it automatic) But you must participate: please paste /etc/os-release and lscpu here. I don't have modern Raspberry pi hardware so I need your setup. This should be enough to "simulate" other platform.

@myloginforgithub sorry for my silly question but I'm not good with ARMs - is armv71 the same as armhf? or these are two different architectures?

[myloginforgithub]

@Bercik1337, i don't know too. But this is output of requested commands. During installation of SCGI package was error about "armhf". Where i can found logs with that? I'm already use rtinst instead of your script.

[Bercik1337]

If i'm lucky I'll fix it this weekend. But to be REALLY sure if it works. Some of you need to run it - as i still don't have modern Raspberry pi. Gonna update this thread when it's done.

They look to be the same per this link

[ballonnetje]

for anyone with an rb pi and having this problem;

Like they said before just replace the link (around line 502, not exactly 502) with the ARM version URL found here under Download > Binary (https://debian.pkgs.org/10/debian-main-arm64/libapache2-mod-scgi_1.13-1.1_arm64.deb.html)

Then everything works :)

[ballonnetje]

Oh BTW, after installation completes the command line stays red.

[Bercik1337]

@ballonnetje yes, script is evolving so line number is changing. I still don't have any available rpi on my hands. So much so I switched to Dell WYSE platform because of that. Perhaps I'll exclude Pi support with next update as some people can't handle this exception.

[ballonnetje]

Tbh this was a quick fix and no need for any stress - at least for me. If it's too much of a hastle to implement the change by all means just don't do it. :)

Btw I don't see why you need a rpi for this right now, but that could be my noob view; You only need a check which system it is: arm or other. Then get the correct link for the system. The rest of the installer worked without any problem on my pi.

[Bercik1337]

it's not that easy, there different architectures of Pi (different CPU arch). That means you can't use the same deb package for all of them. What works for you above, won't work in early versions of Pi. :(

[rjalexa]

For anyone looking at this as of Jan 2024: line to correct is currently 530 replace with package https://debian.pkgs.org/10/debian-main-arm64/libapache2-mod-scgi_1.13-1.1_arm64.deb.html

I have a raspberry 4 model B

I'll try to refresh whatever I can, but i'm chronically out of time :(

[rjalexa]

Ouch sorry that package does not exist anymore :( this seems to work though http://ftp.de.debian.org/debian/pool/main/s/scgi/libapache2-mod-scgi_1.13-1.1_arm64.deb

since this is old but may still be relevant, armv71 and armhf are the same thing, 32 bit arm. armv71 was the name they used on Pi's 1 and 2 before it it needed to seperate arch types. for the most part, like with most 32 bit systems, armhf is pointless.
