[SOLVED] Resolving dependencies (in arch)

Sebi · 2015-10-26 17:55:51

I'm trying to install texstudio in arch and am shown this dependency related error:

$ sudo pacman -S texstudio
resolving dependencies...
looking for conflicting packages...
error: failed to prepare transaction (could not satisfy dependencies)
:: poppler-glib: requires poppler=0.33.0

When trying to install poppler individually the same error is given:

$ sudo pacman -S poppler
resolving dependencies...
looking for conflicting packages...
error: failed to prepare transaction (could not satisfy dependencies)
:: poppler-glib: requires poppler=0.33.0

have you run 'pacman -Syu' recently?

post your pacman.conf

I have run:

pacman -Syyu

before trying to install the package. The output of 'pacman -Syu' is:

$ sudo pacman -Syu

What ooo was trying to say: did you update recently (so, did you answer yes on pacman's question to proceed with the installation)? Running pacman -Syu without updating will get you in trouble when installing packages and that is exactly what your problem is. The local database knows about poppler 0.36, so it tries to install poppler 0.36. But since you did not update poppler-glibc to 0.36, it requires 0.33, blocking the installation.

It is called a partial upgrade and is unsupported. So, the solution is to update and then try again.

EDIT: Substantiation of my claim: https://wiki.archlinux.org/index.php/Sy … nsupported

Also, taking a look at the poppler library commit history shows that poppler should have been updated somewhere between now and the 28th of September...

Oh I got it (doing the update now). But is there a way to update packages and to keep the size of the overall packages as small as possible (avoid installing unneeded dependencies) as I have some storage constraints to respect.

Trilby · 2015-10-26 20:06:39

Pacman does not install unneeded dependencies. It installs only what you tell it to install, and the needed dependencies.

Updating will not always take more space - sometimes less as some packages get smaller. (edit: in this case you'll get an increase, but of only 100MB).

But you will want to occasionally clean your package cache as that will grow indefinitely until cleaned (see paccache -h).

As Trilby already pointed out, pacman installs what you tell it to. This means that there are no unnecessary dependencies installed. Do clean out your package cache and check for orphans once in a while. It is also advisable to take a look at what you have installed that you no longer use. If you are really that space constrained, you may also want to take a look at less space hungry desktop environments like XFCE, MATE and LXDE instead of GNOME or KDE.

That is pretty much all you can do. You need some space to run an OS after all, even for Linux.

Got it working now. Thanks for the paccache tip. After running:

$ paccache -d
==> no candidate packages found for pruning
$ paccache -r
==> no candidate packages found for pruning

paccache suggests that there are no packages to remove. But why is that given that I've just upgraded? Also, installing texstudio worked after the upgrade. But, texstudio shows the following message when launched:

No LaTeX distribution was found on your system. As a result, the corresponding commands are not configured. This means, that you cannot compile your documents to the desired output format (e.g. pdf).

If you intend to work with LaTeX, you'll most certainly want to install a LaTeX distribution.

Following the steps described here:

https://wiki.archlinux.org/index.php/LaTeX

it is not clear which packages include tex.

Read the paccache help - by default it keeps the last 3 versions of everything. That is probably not what you want.

I use `pacccache -rk2` and `paccache -ruk0` regularly.

I use `pacccache -rk2` and `paccache -ruk0` regularly.

The first command gives the output:

==> no candidate packages found for pruning

while the second frees up ~343 Mb of space. But when running the disk storage utility the following output is shown:

http://oi58.tinypic.com/huhavb.jpg

Why are there still 2.2 GB left in the cache? Should I clear everything:

pacccache -rk2 && paccache -ruk2
pacccache -rk1 && paccache -ruk1
pacccache -rk0 && paccache -ruk0

?

You can if you want. All you lose is the option to downgrade.

This may be slightly off-topic but my arch distro is running in a virtual machine (sun virtual box). Are there any risks of damaging files upon resizing the vitual drive as decribed here:

https://forums.virtualbox.org/viewtopic … 35&t=50661

?

Are there any other ways of preserving the previous packages without actually storing them?

Sebi, you should spend some time searching to find answers to your own questions. You should also use each thread on these forums for one issue. This thread started with you using pacman wrong, to running out of space on your drive, to figuring out how to use a well documented tool (paccache), and now to resizing virtual drives and downgrading packages (and this is ignoring skiping over the latex question). This is not an effective way to post.

Please either elaborate on the original problem if it still exists, or mark this thread as SOLVED if it has been solved. If you need to you can open a new thread for your other issues.
