Hello,

See if freeing Lint.jl does the trick.

See also here [Pkg broken: "No feasible version" error](https://discourse.julialang.org/t/pkg-broken-no-feasible-version-error/2347) and here [More Pkg trouble: "unsatisfiable package requirements detected" - #10 by ChrisRackauckas](https://discourse.julialang.org/t/more-pkg-trouble-unsatisfiable-package-requirements-detected/2142/10). I found that checking out master of Images did the trick. The current version is 0.8.0 so there is definitely something fishy about your version for that. Good luck!

Freeing Lint.jl did the trick, but caused the linter plugin of atom to fail.

After update checkout it again until next Lint.jl tag is released in Metadata.
