So I'm trying to install Debian 9.0 to my laptop (UEFI) via DVD and everything worked fine except that the mousepad doesn't work (yet?) and that I'm getting this error:

Debootstrap error
Failed to determine the codename for the release.

at the step "install the base system" after the partitioning.

Any suggestions for what I should try to get it working?
This thread somewhat suggests that some change to my partitioning could solve this issue.
I selected "Guided - Use entire disk and set up encrypted LVM". Changing the 2 ext4 partitions to ext3 didn't help.
Any help is welcome!

Edit: I skipped to step "Check integrity of the CD" and it says The CD of yours is not a valid Debian-CD-ROM. Please change the CD. Note that during installation I connected to the Internet and that I used the same CD for the installation on another PC. Please help.

Edit: Related question of mine. I rebooted and did the integrity-check offline where it says: "Integrity test failed The ./pool/main/k/kde-l10n-de_16.04.3-1_all.deb file failed the MD5 checksum verification. Your CR-ROM or this file may have been corrupted." These days being paranoid is the only reasonable thing to be. I guess I have to reinstall my computer's OS as well as I used the same CD for it?
