USM question

Post#1 by rcrsf » 11 Feb 2016, 07:06

I've been adding some modules via the USM package manager.

Often when downloading, I get the message "More than one package contains..."
For example, on downloading VLC, it says: "More than one package contains: libQtCore.so.4"
And then there is a list of 9 packages to choose from.

My question is: what am I doing/choosing there?
... Choosing another package to download? Even if I don't want it?
... Looking for a package that I already have installed, so that it shares the resource? If so, what if I don't have already one?
... It seems to require choosing something. So if neither of the above, then what do I choose?

Thanks in advance for clarification

These are necessary libraries for the package of interest.

Just tap enter to get the first one on the list or select a number amongst those offered, just one number.

longer answer as loves vlc......this is 64 bit response so your versions may vary

try to choose the most recent version here

1) vlc-2.1.2-x86_64-1dj.txz 3) vlc-2.2.1-x86_64-1alien.txz
2) vlc-2.1.6-x86_64-15_slack.txz

3 is higher
######################################
More than one package contains: libQtCore.so.4
#######################################
qt-4.8.7-x86_64-1_slack14.1.txz 28356K slackwarepatches
qt-4.8.5-x86_64-2.txz 28204K slackware
teamviewer-10.0.36281-x86_64-1_slack.txz 27556K slackonly
insync-1.3.3.36056-x86_64-1_slack.txz 33604K slackonly

skype-4.3.0.37-x86_64-1sl.txz 42659K slacky
copy-client-3.2.01.0481-x86_64-1alien.tgz 19612K alien

qt-4.8.7 is higher.

although the others say they have qt files I always try to choose the most meaningful package in that case its Qt

some other packages may be smaller but you maxmise support by going for the main package choice.

Is that clearer?

Well, I'm not sure what qt-4.8.7 is -- ut let's say for example that I chose "teamviewer-10.0.36281-x86_64-1_slack.txz 27556K" -- does that mean that I'm also downloading teamviewer?
Or does it mean that my download of vlc-2.2.1-x86_64-1alien.txz is going to use "libQtCore.so.4" from teamviewer (but only download the libQtCore.so.4 part from teamviewer)?
I guess I'm also confused why libQtCore.so.4 wouldn't have just been included with VLC if it's required...?

Yes to the best of my knowledge
(but only download the libQtCore.so.4 part from teamviewer)?
You have to take it all, as there may be other parts of the package, which might be needed by libQtCore.so.4.
why libQtCore.so.4 wouldn't have just been included with VLC if it's required...?
Which gets us to the core of the dependencies headache. Its to do with reusable code. Why write an almost similar bit of software, when someone somewhere else is already doing it? :twisted:

So I went to download VLC, and it appeared to require that I download more than 50 different packages... Does that mean I'd have to "load="+50filenames.xzm in order to run VLC? That would probably infringe on my Porteus-ness. I think I'd prefer to get familiar with Audacious.

But please correct me if I'm wrong.

Great, thanks for that! - Found several good modules there.

*How did you find that link?
*Is there a directory of trustworthy "Porteus Package Repos" somewhere?


In particular, a few more packages I'm looking for are: Inkscape, Filezilla and Calibre. Those had so many dependencies on the System->USM utility.

Yes, if you have unlimited storage space.

Say you choose a 25MB app from USM and it needs a 5MB dependency. And the dependency is a common one found in many apps. If you go thru and simply choose the first one on the list or the newest one your 25MB app may turn into a 125MB module.

A shortcoming of USM, when it lists dependencies it doesn't display the size of the various modules it is found in. So, what I do is I write down the names of the various dependencies required then manually use USM to pull each one up and check it's size, which I also write down. Then I reselect the app and as the dependencies are listed I choose the smallest one in each case. In this example you won't end up with a mere 30MB module, it will probably be 50 or 60MB but it won't be 125MB.

Just my opinion and approach.

Another shortcoming is no option to display package description when alternatives are proposed. In that way if one of depndencies is samba, I give it a wide berth, as I know what all this brings with it, but someone without knowledge in this direction has nothing to use even as a rough guide. A frequent exmple I used to get with vlc was cups or aaelflibs. If I chose aaelflibs, if remember correctly, had to get mariadb, and then a whole load of others.

Recent example from poster in Russian section. Did usm under kde for claws-mail and ended up with 27 MB for download. Gave him the usm output to follow. However at third or fourth choice the alternatives diverged from mine. So he went on to try as best he could and ended up with a 270 MB download, almost all of Porteus! Anyway did a barebones XFCE for him and got around 50 MB download which ended up as 52 MB module, which he was happy to report worked.

Yes, I ended up with some pretty large files, which included some dependencies that I have no idea about.

Is there some other method of installing programs on Porteus that I'm missing?
----I tried deb2xzm, but that has depency challenges as well.
----On porteus.org/faq.html , mention is made of "porteus-package-manager", but when I try that command it's "not found".
----At forum.porteus.org/viewtopic.php?f=46&t=1356 , there's talk of "64bit official Porteus repository". Does it still exist?
Unless I'm missing something, then it sounds like Ed_P's approach is the best option...?

Thanks for all the input

I have the current 3.1.9 USM and when I see dependencies it doesn't show their sizes. See attached image.
