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 7:00
  • 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 7:02
  • 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 7:05
  • @UlrikeFischer I have them already - otherwise it would not work at all. – Curunir Oct 16 '17 at 7:10

    BTW: Manual KOMA-Script installation could alternatively be done using the installation package from the KOMA-Script repositoy. – Schweinebacke Oct 16 '17 at 7:22

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.
