Read-only partitions, MyDocs or otherwise, are generally a sign of a file system corruption. The built-in fsck may not always work. I have seen recommendations on this forum to run fsck -a on the affected partition twice in a row. If that does not help and the partituon is easily exportable by USB, such as MyDocs, run the check-and-fix on the PC.

HAM is known to be fussy. It has some extra built-in checks on top of what apt-get would do, presumably to cater for the messed-up situation with Maemo dependencies. FAM, on the other hand, is just a GUI wrapper for apt-get. Some say it's its undoing, I call it an advantage. Anyway, if your instalation is now sorted and neither apt-get -f nor HAM complain, then you can shake your own hand, pour yourself a nice drink, get your feet up and enjoy the peace.
