This error occured when I try to install offline repository.
Hi Rituraj Eastbengal Mukherjee,
Regarding the online installation, on windows machines, this procedure is a little bit slow (it takes 15-20 minutes); try to restart the installation and wait few more minutes.
Regarding the offline installation try to store the tar.xz offline repository in the C: partition of your hard disk (the same that is used for the system installation) before restarting the procedure.
Choose the kind of installation (online or offline) that you prefer; both procedure should work fine.
Note: before restart the installation, you have to delete the zerynth2 folder from your home directory.
Let me know if you solve this issue
