Error during installation step "Configuring APT"

Hey all! Long time no see.

A few weeks ago I've rebuilt my server, with the following specs:

- MSI B250I PRO motherboard
- 8GB RAM
- Pentium G4560 CPU
- 2x 2.5" HGST and 2x 3.5" WD RE3 HDDs, all 1TB in size (a third disk is also in there, but I have no free SATA port at the moment, planning on adding an expansion card soon though)
- Kingston DataTraveler as boot/system drive (replacing it with an M.2 SSD soon)

The main issue is that I cannot finish the installation. The installer works fine up until the moment it wants to configure APT. It asks me for a remote server, where I choose the closest, most reliable one to me (ftp.hu.debian.org), and try to work it. It sits at "Scanning the mirror..." for about a minute or so before showing a red error screen "Bad archive mirror".

The error from terminal is:

choose-mirror[31508]: DEBUG: command: wget -q http://ftp.hu.debian.org/debian/dists/jessie/Release -O - | grep -E ´^(Suite|Codename):´
choose-mirror[31508]: WARNING **: mirror does not support the specified release (jessie)

However I can see on the remote that jessie is perfectly supported. I'm using the latest 3.0.58 ISO from SourceForge.

Is this error known, or is there a workaround/fix?

Just forget about the mirror, choose default or use httpredir.debian.org

Sorry, I forgot to mention that no matter which mirror I choose, this is the result.

The install went through by going for the "install without online mirror" option. However after install I'm still having some issues (e.g. can't update openmediavault package because it depends on python3-lxml, which is, for some reason, not installable).

EDIT:

Okay nevermind, had to manually add the package sources, as they weren't injected during install. After adding

deb http://ftp.hu.debian.org/debian/ jessie main contrib non-free
deb-src http://ftp.hu.debian.org/debian/ jessie main contrib non-free

to the sources.list, it can now update and upgrade.
