Hi, Thanks for working on this!
- s/enebled/enabled/ - "use Ubuntu archive as same as Debian archive" is hard to understand for me; I'm not sure it's correct English; it might be useful to ask the debian-l10n-english team to review the new strings. More generally, regarding the phrasing of the new user-visible strings: the one I have proposed uses terminology found in the APT documentation, for consistency's sake. It seems to me that the one you're proposing here fits less well in the surrounding ecosystem, but YMMV :) Cheers!
