the latest bar-in addition to bundle will match the dependency with the foo plan which have this new digital bundle term, due to the fact significantly more than.

This may make certain that at the most one to provider of that digital plan is unpacked otherwise strung at once.
Packages can also be claim within their control document that they should overwrite records in certain other packages, or totally exchange most other packages. The newest Substitute manage career enjoys these line of objectives.
seven.six.step one. Overwriting files in other bundles¶
It certainly is a blunder to have a deal so you can incorporate files which are into the program an additional package. But not, if the overwriting package announces it Substitute the main one which includes the file being overwritten, up coming dpkg usually alter the file about dated plan having the ones from brand new. The fresh new document will no longer end up being listed since “owned” by old plan and will be taken over by the fresh new plan. Generally speaking, Breaks will be used in combination which have Changes . cuatro
Like, if a great deal foo was put into foo couples seeking men hookup free and you will foo-investigation starting during the version step 1.2-step 3, foo-studies could have the new areas

For this use of Changes , digital packages (see Digital packages – Will bring ) commonly considered when considering a good Substitute profession. This new packages stated as being replaced must be said by their genuine names.
So it access to Substitute simply requires feeling when both bundles was at the very least partially into the system immediately. That isn’t related whether your packages disagreement unless of course the fresh new dispute has been overridden.
eight.6.2. Substitution entire bundles, pushing their reduction¶
2nd, Changes allows the fresh new packing program to resolve and this package might be removed if there is a dispute (find Conflicting digital packages – Issues ).
