You have been subscribed to a public bug: The HEIF image file format [1] is getting quite popular, mainly because this is now the default image format for iOS [2]. Unfortunately, this is not supported by default in Ubuntu (20.04). In practice, this means that if someone sends you a picture from an iPhone, you won't be able to look at it (and the error message in eog is just saying this "is not a image", not hinting at all that installing a small package could solve it).
Therefore, I'd recommend installing by default the following two extra packages.
