I just upgraded my Ubuntu desktop 10.10 to 11.04. I everything works fine except when trying to update the current R 2.12.1 to R 2.13.0.
I followed the readme:
deb http://cran.xl-mirror.nl/bin/Linux/Ubuntu natty/ deb-src http://cran.xl-mirror.nl/bin/Linux/Ubuntu natty/ deb http://nl.archive.Ubuntu.com/Ubuntu/ natty-backports restricted main multiverse universe
and also added
The Ubuntu archives on CRAN are signed with the key of "Michael Rutter " with key ID E084DAB9. You can fetch this key with
gpg --keyserver keyserver.Ubuntu.com --recv-key E084DAB9
and then feed it to apt-key with
gpg -a --export E084DAB9 | sudo apt-key add -
Which appears in the synaptic package manager (so I assume it worked).
but when running
sudo apt-get update I obtain an error saying that:
Reading package lists... Error!
E: Encountered a section with no Package: header E: Problem with MergeList /var/lib/apt/lists/cran.xl-mirror.nl_bin_linux_ubuntu_natty_en E: The package lists or status file could not be parsed or opened. E: _cache->open() failed, please report.
An unresolvable problem occurred while initializing the package information.
Please report this bug against the 'update-manager' package and include the following error message:
'E:Encountered a section with no Package: header, E:Problem with MergeList /> var/lib/apt/lists/cran.xl-mirror.nl_bin_linux_ubuntu_natty_en, E:The package lists or status file could not be parsed or opened.'
how can I solve this? I am not an experienced Ubuntu user but have been using R on Mac and Windows.
