Chroot and dependencies in different repositories

[eniko1556]

There are two questions here:

• ca-certificates and external repos is a chicken and egg problem
• external repositories are non-standard, also apt fails to install if adding as such

The main problem here is that the chroot environment requires ca-certificates present to add additional repositories as the repositories are external.

The second problem is that additional repositories are non-uniform, so adding them is not an easy feat.
