Hi, Mayuresh! Pkg_add/pkg_delete are reliable. Their job, however, is quite simple:
- pkg_add is to install packages and their dependencies (if any); - pkg_delete is to remove packages and (if requested) those that depend on them. Pkg_add can perform a very simple upgrade, but if you request to install/upgrade a package that depends on another package older version of which is already installed on your system you will get an error as pkg_add will blindly try to install the newer version on top of the old (and get a conflict). Pkgin is more advanced: it builds a whole dependency tree and upgrade all dependencies. -- Aleksej Lebedev On Fri, May 10, 2019, at 19:10, Mayuresh wrote: > http://pkgin.net/ says: > > NetBSD, and more widely, all operating systems relying on pkgsrc have > tools like pkg_add and pkg_delete, but those are unable to correctly > handle binary upgrades, and sometimes even installation itself. > > Could someone please clarify what it means?
