Cannot upgrade 3 to 4, still running 3.18.2 from 2021-11-28

I am running a snap install on a Raspberry Pi 4 operating Ubuntu 18.04.5 LTS (GNU/Linux 5.3.0-1042-raspi2 aarch64).

I’ve been running 3.18.2 since 2021-11-28 and snap tells me no updates are available.

I’ve two issues:

  • I can’t upgrade to 4.x because i must be running 3.18.3
  • I’m prompted to action but have no eligible version available

Help!

Here’s my snap output:

You can update to 4.x, that 3.18.3 is specifically for amd64 not arm.
