Standard Notes on Linux

I am a long time user of Standard Notes, and have also previously used on Linux. I have however, mostly due to my old (non-MacBook) laptop having a battery-lifespan of 12 minutes, a broken USB-port, an autonomous trackpad and a partially broken .-key on the keyboard (. is fairly often used by the way...) not used for a while. Enter new laptop. Enter Ubuntu. Fix the usual wobblegobble, when using Linux on a cheap low-grade consumer laptop, and then install applications and apps as needed.

Download the Standard Notes AppImage from the download-page, and then execute the two commands listed on the page. However in my case (Ubuntu 24.04 LTS) it didn't. It gave me this instead:

boegh@Ubuntu:~/TMP$ ./standard-notes-3.195.1-linux-x86_64.AppImage 
dlopen(): error loading libfuse.so.2

AppImages require FUSE to run. 
You might still be able to extract the contents of this AppImage 
if you run it with the --appimage-extract option. 
See https://github.com/AppImage/AppImageKit/wiki/FUSE 
for more information

For whatever reason, it is assumed that FUSE is installed on all entities. In my case it was not. However the linked page easily remedied that. That didn't quite cut it though. As what happened next was:

boegh@Ubuntu:~/TMP$ ./standard-notes-3.195.1-linux-x86_64.AppImage 
[10493:0728/120941.993177:FATAL:setuid_sandbox_host.cc(158)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /tmp/.mount_standaUF49Nx/chrome-sandbox is owned by root and has mode 4755.

Solution number two on Solve “The SUID sandbox helper binary was found, but is not configured correctly.” (3 solutions!) helped me with that (running the AppImage with the argument --no-sandbox. What the actual implications on running it with that argument is, I'm not sure of, but it works.
