My computer is dual booting windows 7 and ubuntu (12.04). My ubuntu partition has an encrypted root and home. The trouble is that for a while the /root partition has been almost full (94% to 98%. I haven't been able to run updates without being very selective because of the lack of space.I try to clean up the root directory, but it never clears up more than 100 or so mb of memory. The /root partition has 5.5GB of space, which is apparently not enough, although it is more than what was recommended by a guide I originally used. Basically, I have tons of free space on my /home and I'd like to shrink it and reallocate the free memory to the /root. I can't figure out how to deal with the resizing on encrypted partitions.
Additionally, I do have a good amount of completely unallocated space (about 25gb) available, so if adding some of that to the /root is an easier process, then some instruction on that would also be really helpful. I'm still a beginner with linux, so clarity and details (& explanations) would be much appreciated.
Lastly, I've gone through the ResizeEncryptedPartitions post, but had trouble with adding the free space to the encrypted partition.
