openSUSE leap15 updating problem

I have just loaded openSUSE leap15 on my PC. When trying to update receved info:
Update error
For repo /var/cache/zypp/packages/repo-update/x86_64/libpackagekit-glib2-18-1.1.10-lp150.3.3.1.x86_64.rpm 57290afc73406fbb4614681a483f6fa47d81ba57537e673aca20a9516df3d75e is requested but 679631b4604d58ed02fd8aabb9c5ae69be6908778d9cee5c6751048640deddd2 was found!

The similar happened while trying on konsole 'sudo zypper dup', followed with possible acceptance the situation, however it may be dengerous for the system.
Should I accept the risk?
I am quite new openSUSE user.

Several people are reporting the same problem. See:

[opensuse] Corrupt files in update repository

https://lists.opensuse.org/opensuse/.../msg00261.html
[opensuse] Digest verification failed when doing system upgrade

Please do:

zypper clean
zypper ref
zypper up

I have done your suggestions but it does not helped.

"zypper dup" is for distribution upgrade, when you are moving from one major version to another and not needed for generic system update. For system update, use "zypper up". Note that if you are on Tumbleweed, you are supposed to use 'zypper dup'. But you say you are on Leap.

The error message you posted above is for only one package. Could you run the commands given by mrmazda again and post the full output of "zypper up" ? (Inside CODE tags)

Seems people who switch to individual mirror(rather than download.opensuse.org, which is only a redirector) do not face the problem. [On a personal note, I have not faced this & I use individual mirrors.]

OpenSuSE mirrors are here.

If you are unable to solve the problem using the already provided instructions, please provide output from

zypper lr -d

wrapped in CODE tags.

Thank you everybody for their help. The problem is solved, as Sauerland explained. Updating of my system went smoothly.
