What Arch package is libxxf86dga from?
Hi: Yesterday I did

pacman -Rdd libxxf86dga
Now mplayer won't start:

bill@darkstar/almacen/cine/Chicago (2002)$ mplayer Chicago.2002.720p.x264.mkv
mplayer: error while loading shared libraries: cannot open shared object file: No such file or directory
bill@darkstar/almacen/cine/Chicago (2002)$

I searched in with the keyword libxxf86dga unsuccessfully. I also searched in Google. Could you tell me what Arch Linux package is that from? I aim at getting that library back (pacman -S the_package_name).

This package is in the AUR.
I wonder what mplayer version you're using there.
I suspect - from your last thread - that you are running some sort of Franken-Arch there. You need to fix those keys. Or, depending on how long you went without upgrades, a reinstall might be necessary.

# pacman -S libxxf86dga

You need to stop looking for individual packages in the repository. Arch does not work like that. When you get your machine up to date with pacman -Syu, all correct dependencies will be installed.

You removed libxxf86dga, but did not update the machine all the way. The solution is not to go looking for libxxf86dga. Get the machine to update with pacman -Syu Until you do, you have a partial updated mess.

Thanks knudfl. I already did that, but

bill@darkstar~$ sudo pacman -S libxxf86dga
error: target not found: libxxf86dga

Yesterday I began reinstallation. But the image was old and pacstrap waited ~120s before loading each package (pacstrap /mount_point base). So now I will download the ISO image from the torrent.

And now a question: should I erase the whole partition before reinstalling (I use only one partition for the whole OS)?

Depends on what kind of install that you are doing. MBR/GPT BIOS/UEFI
What bootloder that you are using. Grub on MBR needs it's own little partition, EFI needs its own partition,...

Use this

Not utube videos.

Read the wiki first.

I use BIOS and MBR, and I made last install with grub without a partition for itself.

If I install above what I already have on the partition I wouldn't have to deal with grub again, which would be a great advantage for me.

I already told you that the real problem is here. You have to fix those keys (signatures) so you can upgrade your system.
Instead of fixing what is broken, you unsuccesfully open a new thread, then decide to reinstall. With that attitude you will never succeed with any OS, and most certainly not with Arch Linux.

It's been over a year since I last made a successful general upgrade. You yourself said it would then be advisable to reinstall.

If you don't want to reinstall, you can begin the slow process of upgrading from Arch archives, you won't need every day of every month, but probably at least one/month since last upgrade to be on safe side.


teckk #11:
Don't blindly update arch. Read the news first thing.
good advise - thanks! ignore the 1/month info

teckk 04-06-2020 07:21 AM

You can update a 5 or 6 month out of date arch install. It depends on what major changes have been made. Look at the arch news.
If nothing is going on, the longer you wait the larger the update will be, but it'll update fine.

When there is a manual intervention needed, go ahead and get that done. If you let 2 or 3 of them pass, then you might be in a mess, or at least have a much harder update to deal with.

Don't blindly update arch. Read the news first thing.

just in case something like this happens again - you can actually search for a filename in packages! first download file databases with


pacman -Fy
then do


pacman -F
... and now i noticed that the package is from AUR :\ this method doesn't work with AUR, but the point still stands, I think many people don't know about such possibility

if you need to find, say, what package a binary comes from, do


pacman -F /usr/bin/mplayer
