Unable to install Firefox in 32bit Trinity 2026 Version

I have installed the last Q4OS 32bit distribution into an old computer with a Pentium M 1,7hz computer with 1GbRAM. Q4OS works very well and nice. From the initial wellcome screen I installed private codecs first and then the rest of apps installed from the complete desktop profile.

Everything well, but the chromium browser does not work. When started it shows the message "the system lacks support for the sse3 instruction set". No matter as it is the Firefox browser what I really need and wish. So I tried to install the Firefox browser, it is ready from the  Software Center:

It starts to be installed but stops at the 52% with the following message: (translated from spanish): "The simulation was not made correctly. Sorry, the installation cannot continue... cleaning and cancelling"

I believe something previous is needed to be installed. If it cannot be solved, this 32bit distribution is worthless for me. Thanks in advance to whoever could help me.

Welcome to the forum

We will check Firefox installer for 32bit systems. In anyway, you can try installing Firefox ESR from repositories:
$ sudo apt install firefox-esr
and post back the result.

We have tested FF setup from the software center and all works just fine. Please run in terminal and post back the result:
$ get-q4os-version
$ sudo apt-get check

Moreover attach the files below or ship them via e-mail support@q4os.org for us to anaylyze:
/home/<user>/.appsetup2/log/setup-q4os-firefox_*.log

Re: Unable to install Firefox in 32bit Trinity 2026 Version

Thank you for your quick  answer and support!!

1. The 'sudo apt install firefox-esr' command worked perfect and it was installed, but it could not be seen as installed.  So I created an icon pointing to /usr/bin/firefox-esr to be able to start it.

2. Today 14th the firefox-esr app appears as installed at the new apps folder. I expect it will self-migrate to the normal installed folder

4.I already set email with the *.log files asked for. Also included the 'version' and 'check' text files you asked for, as answers to your 'get-q4os-version' and 'sudo apt-get check' commands

5. Ramdomly the system reboots (once every day). Last month I believe this same problem was solved when I installed a 32bit Lubuntu version, by adding a 'forcepae' option at the start. Maybe it is also needed at the start of your Q4OS 32-bit distro.

Thank you again, patxi-p, Madrid,Spain
