I am on Ubuntu 20.04 LTS. When I go into the Ubuntu Store, I find that there are two updates ready for snapd and core. When I try to apply the updates, I get this error:

Unable to update snapd: snap has no updates available

I get the same error if I try to update core with snapd above replaced by core.

What I've done to solve the problem: I tried running sudo apt update && sudo apt upgrade, which I didn't believe would solve the problem, but it was worth a try. It didn't work, as expected. I then typed up the error on the internet to see if that would help. I found nothing except this question on AskUbuntu by user preIdiot that is similar to mine but has no answers. I tried running the sudo snap refresh command suggested in one of the comments, and got All snaps up to date.

Honestly, I'm really confused at this point. The Ubuntu Store says there are updates, but snap says there are none. What is going on, and how can I fix it, if applicable?

I'm not sure if this will help, as the issue is software rather than hardware related, but posting my specs can't hurt, as provided by neofetch:

system specs

UPDATE: I'm not sure where I'm supposed to be making updates, but I'll do it here for now. The problem has disappeared on its own.

    I don't think the question should've been closed. Anyway, my guess is that the problem could be in incomplete system upgrade, needing to reboot... I managed to make my problem disappear. – Heimdall Sep 05 '22 at 08:05
  • There's no point in handing a question on a problem that disappeared in its own or goes away with a reboot. There's nothing anybody can do about the former and the latter is step 0 of IT troubleshooting. – muru Feb 27 '24 at 01:19

Ubuntu users who use 20.04.4 LTS or later can use:

killall snap-store

Open a terminal and type

killall gnome-software

You shouldn't need to use sudo.

On reopening Software it will re-index and should remove the problem.

    I'm not 100% sure if I'm right on this, but isn't the app store in Ubuntu 20.04 called the snap-store? So shouldn't gnome-software be replaced by snap-store? Or should I just use the suggested command verbatim? – Vishal Bagadi Mar 05 '21 at 13:48
  • It's what worked for me with the same issue. In the linked questions/answers you will see that there is confusion around gnome-software and snap-store. – graham Mar 05 '21 at 14:06
