SOLVED - Pacman update error

Hello,

I am trying to update my Arch using terminal with command "pacman -Syu" to which it gives the following message-

:: Synchronizing package databases...
core is up to date
extra is up to date
community is up to date
multilib is up to date
:: Starting full system upgrade...
resolving dependencies...
looking for conflicting packages...
error: failed to prepare transaction (could not satisfy dependencies)
:: ffmpeg2.8: installing x265 (2.7-1) breaks dependency 'libx265.so=146-64'

Information about my Arch is as follows-

4.15.7-1-ARCH; x86_64 GNU/Linux

What should I do to have this resolved?

Thanks a lot!

Re: SOLVED - Pacman update error

As ffmpeg2.8 has been dropped from the repos and nothing should depend on it anymore, remove ffmpeg2.8

vlc had a dependency on ffmpeg2.8. After upgrading vlc I was able to remove ffmpeg2.8 and update ok.

I am trying to remove 'ffmpeg2.8' using- "pacman -R ffmpeg2.8" to which it gives me the error:

checking dependencies...
error: failed to prepare transaction (could not satisfy dependencies)
:: vlc: removing ffmpeg2.8 breaks dependency 'ffmpeg2.8'

How should I remove it?

I have removed 'vlc' with 'pacman -R vlc' and then removed 'ffmpeg2.8' in a similar way. I then reinstalled 'vlc' using 'pacman -S vlc'. I know this is a long route but did get the job done!

Make sure you complete the upgrade now (pacman -Su or just -Syu).

upgrade path broke for x256 due to strict soname depds, therefore we re-add ffmpeg2.8 temporarily to provide a more fluent transition.

Should allow a normal pacman -Syu to proceed then ffmpeg2.8 can be dropped again after a transition period.

This really helped solve the issue.  though i seem to have multiple packages which required me to run the same command. But all in all. I am happy and updated everything.

Thanks

Re: SOLVED - Pacman update error

Glad to hear but please don't necrobump 2 year old threads (though I do wonder how this issue could still be a problem on a remotely updated system)

Closing.
