Package: perl Version: 5.10.0-16 Reading package lists... Building dependency tree... Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.
Since you only requested a single operation it is extremely likely that the package is simply not installable and a bug report against that package should be filed. The following information may help to resolve the situation: The following packages have unmet dependencies: perl: Depends: perl-base (= 5.10.0-16) but 5.8.8-7etch3 is to be installed Immediately after installing Etch, I changed the /etc/apt/source.list file by replacing etch with lenny. # apt-get update # apt-get install perl yielded the above error message. The same error occured when I upgraded a machine the 4'th of November, the work around I used was to uninstall perl and then reinstall perl along with all the packages that depended on it.
