KOMA-Script Installation fails

Question

Because I am using a Proxy in our company using the auto install of the MiKTeX Package Manager does not work for me. Instead I tried installing it manual by downloading the pgf.tar.lzma from a mirror.

When I try to add the package I get the following error message:

package="koma-script", arhiveFile="C:\Users\user\Documents\latex-packages\koma-script.tar.lzma", expectedMD5="8540ac6593530e7b58d865a2f227ea5e", actualMD5="5faf6bfa841513bcfbd4a968ca52a495"

Is there a way to bypass the checksum mechanism?

unless I misunderstood the question, if the checksum is wrong it will be the wrong file (or a truncated file), so bypassing the check won't help — David Carlisle, Oct 16 '17 at 07:00
if auto-install doesn't work you could use texlive rather than miktex which doesn't try to download packages on the fly in the same way. — David Carlisle, Oct 16 '17 at 07:02
It is not enough to download only the pgf.tar.lzma, you also need the suitable miktex databases (the two files starting with miktex-zz). Put them in the same folder (some folder outside miktex) as the pgf-lzma and then use this folder as local repository. — Ulrike Fischer, Oct 16 '17 at 07:05
@UlrikeFischer I have them already - otherwise it would not work at all. — Curunir, Oct 16 '17 at 07:10
@DavidCarlisle I dont want to install another packet manager. Also I have downloaded the package from a CTAN mirror so it should work...+ — Curunir, Oct 16 '17 at 07:10
But do you have the suitable versions? Did you download them at the same time from the same repository as the package you are trying to install? — Ulrike Fischer, Oct 16 '17 at 07:15
I don't think, that pgf.tar.lzma will be the KOMA-Script package. — Schweinebacke, Oct 16 '17 at 07:19
yes apparently there was an update on the miktex packages - thanks guys — Curunir, Oct 16 '17 at 07:19
BTW: Manual KOMA-Script installation could alternatively be done using the installation package from the KOMA-Script repositoy. — Schweinebacke, Oct 16 '17 at 07:22

If you create a local repository for MiKTeX you always should download all files from the same server/mirror. Otherwise it could happen, that the version information at the package management files miktex-zzdb1-2.9.tar.lzma and miktex-zzdb2-2.9.tar.lzma do not correspond with the packages you've downloaded.

So for installation of KOMA-Script from a local repository you have to download at least miktex-zzdb1-2.9.tar.lzma, miktex-zzdb2-2.9.tar.lzma and koma-script.tar.lzma from the same server, copy it to one (new) directory and do the installation from that local directory. Note, if you are using the generic download URL http://mirrors.ctan.org/systems/win32/miktex/tm/packages/… for the download, the mirror can be different for each file. So please use a dedicated server address from the CTAN mirrors list.
