Advantages/Disadvantages of installing from source code [duplicate]

Solution 1:

Well i can say compiling from source is an unsupported method of installing software because it bypasses the Package Management System (APT, USC) completely.

Also it affects system Stability, could break other dependencies . Since Ubuntu Packagers makes sure its all round effectiveness and integration to current system remains intact , therefore installing from official Repositories is recommended.

Also for further reading , refer this and this.

Solution 2:

When installing from source, it will typically install into /usr/local/ rather than /usr (so as not to install conflict with system libraries. This is typically picked up first in paths, so what's in /usr/local/ will always be used first. So if you upgrade and get a newer conky from Ubuntu, when you try to run it, it'll run the old one from /usr/local/ instead. (This can get particularly confusing with libraries...)
