I can't update it say "could not satisfy dependencies"

General system

I tried running sudo pacman -Syu because it said there are 18 upstream updates. But I can’t do the update pacman stop with below message.

Do I have to remove ffmpeg?

Remove ffmpeg3.4
Update system
Re-install ffmpeg if needed.

It needs rebuild against new dependency.

Cool … should I do a pacman -R ffmpeg or a pacman -Rnsc ffmpeg?

4

This should suffice

PS. I almost never do -Rnsc on my system. Of course, you can do anything as long as you know what the command does :grin:

Tried it gave me this.

Thinking of -Rc it allows me to remove.

You could try - won’t lose anything as long as you install the packages back. I could update my machines without any issue, but this was reported on Arch Linux subreddit.

@dalto will know better :sweat_smile:

So the ffmpeg thing is not just me. Thank you.

Side note : I suppose you have to remove ffmpeg3.4 instead of ffmpeg.

I see I also have megasync. Thank you, friend.

-Rc in plain english means remove this package and also remove anything that would stop this package from being removed. As longs as you pay attention to the list of packages it will remove.

That being said, in this case, replacing ffmpeg3.4 with ffmpeg probably would have been a simpler solution, like this:

yay -Syu ffmpeg

That would have let you keep all the dependencies installed.
