When I try to update angular using ng update @angular/cli @angular/core, I get the following error:

Package "codelyzer" has an incompatible peer dependency to "@angular/compiler" (requires ">=2.3.1 <8.0.0 || 7.0.0-beta <8.0.0" (extended), would install "10.1.6"). Package "@angular-devkit/build-angular" has a missing peer dependency of "@angular/localize" @ "^10.0.0". Package "@ng-bootstrap/ng-bootstrap" has an incompatible peer dependency to "@angular/common" (requires "^8.0.0" (extended), would install "10.1.6"). Package "codelyzer" has an incompatible peer dependency to "@angular/core" (requires ">=2.3.1 <8.0.0 || >7.0.0-beta <8.0.0" (extended), would install "10.1.6"). Package "@ng-bootstrap/ng-bootstrap" has an incompatible peer dependency to "@angular/forms" (requires "^8.0.0" (extended), would install "10.1.6"). Package "tsickle" has an incompatible peer dependency to "typescript" (requires "~3.3.1", would install "4.0.3"). Package "@angular/http" has an incompatible peer dependency to "@angular/platform-browser" (requires "7.2.16" (extended), would install "10.1.6"). Incompatible peer dependencies found. See above.

What is the meaning of incompatible peer dependency?

How to fix each one of these requirements?

try ng update codelyzer first, then ng update @angular/core @angular/cli, and ng update @angular/material if it's need

If you encounter Package "codelyzer" has an incompatible peer dependency to "@angular/compiler" please run ng update codelyzer@latest. This will update it in the package.json.

Thereafter you can run ng update @angular/core @angular/cli ( For updating to Anguar 11 ) again. In my case this worked well.
