Bug#54646: base-config: destroys existing sources.list

[Lazarus Long <lazarus@overdue.dhis.net>]

Package: base-config
Version: 0.02
Severity: grave

       3) Dangerous bug. Makes the package in question unusable by anyone or
       mostly so, or causes data loss, or introduces a security hole allowing
       access to the accounts of users who use the package.

Data loss.

/etc/apt/sources.list is overwritten apparently, and those of us with
a significant one will have trouble recreating.

# wc sources.list
     72     285    2810 sources.list
