Hi guys!
Yesterday I opened a thread in Updates/Upgraded section but now the problem is bigger than before...
I have a NAS with OMV 3.0.99 and all worked so fine until the last week, the Plex website notified me an update so I opened the OMV GUI and no updates were availabled, I refreshed them and an error occurred:
Code
Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C; apt-get update 2>&1' with exit code '100': Ign file: InRelease Ign file: Release.gpg

They have been ignored, or old ones used instead.A kind user tried to help me and told me to comment out the jessie-backports and replace the repository i was using claiming there was a problem in the repository I was using, so i did it.
I edited 2 files:
- "openmediavault-kernel-backports.list" in "etc/apt/sources.list.d/" replacing deb http://httpredir.debian.org/debian jessie-backports main contrib non-free with # deb http://httpredir.debian.org/debian jessie-backports main contrib non-free
- "sources.list" in "etc/apt/" replacing deb http://debian.fastweb.it/debian/ jessie main with http://httpredir.debian.org/debian/ jessie main
and I did an apt-get update.
Now I can't even reach the OMV interface from browser, I can only access the NAS with SSH and I really don't know how to fix the problem...
I attach the txt with the apt-get update error, in english would be something like:
Code
W: Impossible to reach http://httpredir.debian.org/debian/dists/jessie-updates/InRelease Immpossible to find "main/source/Sources" in Release file (wrong sources.list or damaged file)
E: Impossible to download some files with address: they will be ignored or older versions will be used.Please guys there is someone can help me? 
Thank you so much in advance

ryecoaaron helped me a lot in another thread and this list of commands have been helpful in solving the problem:
Alles anzeigenTry the following lines (as root):
sed -Ei "s/(stable|oldstable|jessie)/stretch/g" /etc/apt/sources.list.d/* /etc/apt/sources.list
apt-get update
apt-get install proftpd-basic=1.3.5-1.1+deb8u2
apt-mark hold proftpd-basic
apt-get install openmediavault
omv-release-upgrade
After reboot:
apt-get update
apt-mark unhold proftpd-basic
apt-get dist-upgrade
