since my version of R is not compatible with a package I need for my work I wanted to update it today but received the following error message when trying to download the updates with synaptic:
W: Failed to fetch http://ftp.yalwa.org/cran/bin/linux/debian/squeeze-cran/r-base-core_2.15.0-1~squeezecran.0_amd64.deb Could not resolve 'ftp.yalwa.org'
W: Failed to fetch http://ftp.yalwa.org/cran/bin/linux/debian/squeeze-cran/r-cran-boot_1.3-4-1~squeezecran.2.15.0_all.deb Could not resolve 'ftp.yalwa.org'
... and several other messages all pointing towards yalwa.org , can't post them due to spam prevention
well the given urls seem to be outdated, how can I fix this?
