dselect vs. apt-get
hello well I am sorry if this has discussed to death, I didnt find a comparison. I always thought dselect/apt-get are frontend for dpkg. dselect uses ncurses, apt-get is only command line. dselect offers a manual dependency resolving while apt-get (mainly) just downloads the file and calls dpkg... my question is due dependencies, are they resolved the same way, either if you use apt-get or dselect? or are there any differences. I have recently made the experience that dselect worked on a specifig update (cdroast) while apt-get gave my dependency problems... Is the difference that dselect calls database, once you use it, while apt-get first calls dpkg and than dpkg calls the database about dependencies? thanks!

I don't know the internals about when things are called. Both seem to use their own mechanism for initial dependency resolution and then dpkg will later insure that the dependencies are met when it does its dirty work... Also, if you track woody or sid, you probably want to use dist-upgrade rather than upgrade for apt-get. The first will install dependencies that aren't already installed and remove conflicting packages, whereas the second will only update installed packages (usually not sufficient for tracking an unstable branch). I usually use the -du options to an apt-get dist-upgrade so I get a clear report of what it intends to do and that the installation doesn't happen 'til I've got all the packages. deity and aptitude are nice frontends as well -- a little buggy yet... -- Eric G.

Well, dselect typically uses the apt back-end as its access method. I believe the primary difference is that dselect maintains its own package database which is based on the one built by apt. Overall, dselect seems to be more robust at handling package dependency conflicts, and is more expressive :). For example, it won't just mysteriously hold packages back; it'll tell you exactly what's going on. If you check back in the archives a month or two back, you'll find plenty of posts by Joost that will explain this stuff much better than I can.

Dselect vs. apt-get... thank you!
This isn't a question, but a 'thank you' to whoever it was that mentioned in one of the posts sometime this week about doing a dist-upgrade with dselect instead of apt-get dist-upgrade. I'd been trying to upgrade to Woody for about 3 weeks without any success by using the apt-get method. After I read someones suggestion on using Dselect instead (because of it catching the recommends and suggests), I tried it out, and lo and behold it worked! Finally!! Unfortunately I deleted that message, and so I'm not sure who that dselect proponent was, but to whoever it was, thank you! Jeremy
Re: dselect vs apt-get
Thanks for the feedback...
(http://www.debian.org/doc/debian-policy/ch2.html#s2.2). However, it
only does this up until the first time you exit dselect's Select
screen and accept the choices there. All you should need to do is run
dselect, turn off all the things it selected for you ('D' might do this?
Not sure, I used dselect from the start and never ran into this problem
myself), and then quit. From then on dselect should be in a sane state.
Hard to do. It only gives me the list, and it's a good 100 items, when I
select something then click on install. It says adding...
I'll see what I can do again...
[Do you mind if I send this on to debian-user? I'm not exactly
Of course, I'll do the same. Dselect is a popular pastime on the list :)

Hey, I think I finally got the hang of i-
dselect vs apt-get
i've always wondered... 1. equivalency of updating the system is dselect's update EXACTLY equivalent to apt-get update? does one of them update the other? if they're not equivalent, how are they different? 2. intelligence of dependencies and conflicts are dselect and apt-get equally intelligent when it comes to things like package dependencies and conflicts? 3. status of the system and updates are dselect and apt-get's knowledge of installed packages, package status, available packages and provided files the same as each other? i would think that the answers should be yes, yes, and yes. but i've read things that hint otherwise. thanks! pete pgpEY0wJwFiVh.pgp Description: PGP signature

If you use apt-get method in dselect, then `dselect update' will call `apt-get update'. Nevertheless, `apt-get update' won't update dselect database ... 2. intelligence of dependencies and conflicts are dselect and apt-get equally intelligent when it comes to things like package dependencies and conflicts? Apt-get don't present you package in `Suggest:' (which can be annoying for vim that suggest vim-rt, for example), while dselect does. 3. status of the system and updates are dselect and apt-get's knowledge of installed packages, package status, available packages and provided files the same as each other? I guess, since they both use dpkg. But apt-get don't install packages selected in dselect unless you use `dselect-upgrade' action. i would think that the answers should be yes, yes, and yes. but i've read things that hint otherwise. I think this is no, no and no. thanks! pete Bye -- DEFRESNE Sylvain pgpHjrb4tSNXm.pgp Description: PGP signature

I guess, since they both use dpkg. apt keeps its own cache of package status, which is in a format that it can read faster than dpkg can read its own. Unless something has gone badly wrong, though (or, in the case of available packages, if you've used 'apt-get update' rather than 'dselect update'), they will be in sync. -- Colin Watson [EMAIL PROTECTED]
