Dear Opera Software A.S.A.
It’s nice that you employ SecureAPT for your package repository, however, the effect is slightly lost by you replacing the key each year, never signing any of them, and putting them up on an http but not https site.
Update 18.08.2011 – please refrain from putting a file /etc/apt/sources.d/opera.list inside your binary DEB packages, as well. As a system administrator, we may very well have mirrored the binary packages, and do not want accesses to external APT repos, for a shitload of reasons. Honestly. (Lintian could warn about it…)
If you don’t get the message, please contact me. Or any of my fellow Debian Developers. Thank you very much.
