Problem with Linux installation

Post by Vargánya Művek » 2026-02-14, 09:38

I am currently trying to install Palemoon onto Linux Debian 12 the intended way of making use of the official tarball. When run in the terminal though, it says "Érvénytelen utasítás" (invalid command). This is all it outputs, absolutely nothing else. I made sure to get the dependencies needed to run it, and they were installed beforehand: libgtk-3-common, libglib-2.0.0, libpango-1.0.0, libstdc++6, libdbus-glib-1-2.

Code: Select all

volga@canyoufeelthesunshine:~/Dokumentumok/SZOFTVEREK/palemoon$ ./palemoon
Érvénytelen utasítás
volga@canyoufeelthesunshine:~/Dokumentumok/SZOFTVEREK/palemoon$ ls -l ./palemoon
-rwxr-xr-x 1 volga volga 188048 jan   22 05.04 ./palemoon
This is the output.
The system config is:
Kernel:Linux 6.1.0-42-amd64 x86_64
MATE 1.26
3,7GiB RAM
Intel® Pentium(R) CPU G2030 @ 3.00GHz × 2
Mesa Intel® HD Graphics 2500 (IVB GT1)

Did you know that there is no need to "install" it? I simply extract the folder "palemoon" from the tarball into a folder in Home (currently I use the Templates folder) and run it from there. I create a panel shortcut to it with the command: /home/ron/Templates/palemoon/palemoon

Simple as pie. No need to "install."

Uuhhhhh yeah, sorry. I meant running it from the extracted folder.

Try replacing ' palemoon$ ./palemoon ' with ' palemoon/palemoon '

What do you mean by that? That $ sign is part of the command line, I cannot change it

Why do you want to open it from the terminal? Anyway, here's what mine looks like if opening from the terminal:

ron@ron:~$ /home/ron/Templates/palemoon/palemoon

EDIT
I see, you're opening the palemoon folder in a terminal window. Why?

After some Googling, I believe this actually means "invalid instruction" - meaning Pale Moon tries to run a CPU instruction that is not supported by your CPU.
The official 64-bit builds of Pale Moon require a CPU with AVX support (see system requirements), it seems that your CPU is too old for that. You can try using the contributed SSE2 builds instead which should probably work on your machine: https://forum.palemoon.org/viewtopic.php?f=40&t=27873

I can confirm this is the case. The G2030 spec sheet on intel's website lists:
Intel wrote:Instruction Set Extensions - Intel® SSE4.1, Intel® SSE4.2
It does not support AVX, and you'll need to run the community contributed SSE2 version.

You're probably right. My responses were barking up the wrong tree.

Vargánya Művek, I too have to use the SSE2 build.

I had the same issue until recently.

My previous Pentium G5400, despite being an 8th-gen 'Coffee Lake' SKU, had had the AVX instruction deliberately removed BY Intel themselves.....to "push" the user into shelling-out for a more expensive CPU.

I've recently replaced it with a second-hand Core i7-8700 (same generation). This, like all other 'Coffee Lake' chips, DOES have the AVX instruction set. As a side-effect, this means I can now run the official release, as opposed to one of the 3rd-party builds.

'Problem' solved.

@ Vargánya Művek

Just curious. I use Debian with Xfce, but a newer version (13.3).

I see you are using Debian 12 (Bookworm) Mate. Debian 12 Bookworm was released publicly on Jun 10th, 2023. Security support ends on Jun 10th, 2026. The distribution gets a two-year long term support (LTS) version with support ending on Jun 30th, 2028.

Is there a reason why you are not using Debian 13 (Trixie), specifically at the time of this posting, version (13.3)? Debian 13 was publicly released on Aug 9th, 2025. It will have its standard security support till Aug 9th, 2028. The release will be supported for long term support (LTS) for two more years with support ending on Jun 30th, 2030.
