@ldez please, what is correct way to fix message WARN [runner] The linter 'maligned' is deprecated due to: The repository of the linter has been archived by the owner. Use govet 'fieldalignment' instead.? Just add govet and remove maligned?

yes you just have to disable or remove maligned and add fieldalignment to the govet configuration:

    - maligned

      - fieldalignment
    - maligned

    enable-all: true

@ldez ok, thanks, now it works and it writes a lot of warnings, e.g.:
fieldalignment: struct with 16 pointer bytes could be 8 for:

type RhAccount struct {
	ID   int
	Name string

What does it mean, please? I can not find any explanation anywhere.

This is about "struct size" fieldalignment linting, not about "pointer bytes" you've triggered. "Pointer bytes" refers to how much of a struct bytes GC has to scan in order to check the memory, not struct size itself.

See explaination at golang/go#44877 (comment)

#1825 is about making this second type of check non-default as per author intention indicated in comment above. (As it was the case with maligned used in golangci-lint).
