update-core not working anymore

[jpsdr]

Hello.
Since the last core system update very recently, update-core command is not working anymore.

[elieux]

It was replaced by functionality in pacman. Our wiki was updated to reflect that. Just use pacman -Syuu. If core packages update, follow instructions and repeat.

@elieux, excuse my noobness but isn't the project going to merge -Suu option with -Su (as in original pacman) ? So as to keep differences between both implementations minimal.

[elieux]

What do you mean? The upstream pacman manual page also mentions differences between -Su and -Suu.

the main page wasn't updated yet to reflect this change, however.. (the one most people will use/see)

My usual problem with MSYS2 was, that after every update, "update-core" were missing and I had to run pacman -S bash pacman pacman-mirrors msys2-runtime to get it back.
Hope pacman got improved in this regard and it's more reliable from now on.

edit:
is it normal to have pacman -V say v4.2.1-516-g52073-dirty - libalpm v10.0.1
I also had to make a copy of pacman called pacman2 and run pacman2 -S pacman because it said Pacman v4.2.1-273-gfa50-dirty - libalpm v9.0.1 before... So I'm not sure if everything is correct now...
Though on forced install, it'll say warning: pacman-5.0.1.6403.520736d-1 is up to date -- reinstalling

@White-Tiger Pacman v4.2.1-516-g52073-dirty - libalpm v10.0.1 if most recent version of pacman. You had Pacman v4.2.1-273-gfa50-dirty - libalpm v9.0.1 because you were downgrading pacman to restore update-core which was deprecated. If you are unsure if everything is ok you can force downloading latest database and updating/downgrading packages with pacman -Syyuu.
If everything is fine you will see this output:

I wasn't downgrading anything myself.. I've always been using update-core as "suggested" but it also deleted itself after every update... (before it got officially removed)
By running pacman -S bash pacman pacman-mirrors msys2-runtime I've simply forced a reinstall of all core components which was mostly needed to get update-core working again..

And yesterday, I've just run update-core and let it do its stuff, restarted MSYS2 (by clicking the close button) and then used pacman -Syuu which didn't touch any core files and only updated MinGW and other stuff.
After all that, I've been stuck at the old Pacman v4.2.1-273-gfa50-dirty - libalpm v9.0.1.
Running pacman -S bash pacman pacman-mirrors msys2-runtime just yields the usual errors

and to really update pacman, I had to run a copy of it, so it was able to replace the original

Yes, we're waiting with that change until we release new installers. With the current installers, you have to run update-core at least once.

is it normal to have pacman -V say [...]

It's a known issue. The internal version number doesn't correspond to the actual version.

error: cannot remove /usr/bin/msys-2.0.dll (Permission denied)

This is wrong. The runtime should be able to replace files even when they're in use. Is your MSYS2 installed on a FAT volume or on a volume with the Windows Recycle Bin disabled?
