How do I upgrade ubuntu on a USB key?

Asked by Tudor Holton on 2009-11-03

I installed Ubuntu 9.04 on my USB key using the Ubuntu Startup Disk Creator with persistence enabled and have been happily running Ubuntu from it for awhile.

However, now 9.10 has arrived and I would like to upgrade.

If I upgrade from the key, then do all the upgraded packages take up space on the casper-rw part of the disk?

If so, how do I replace the install created by the 9.04 version to the one created by the 9.10 version without overwriting my changes in casper-rw? Should we have a tool for this process?

Cheers,
Tudor.

sudo update-manager -d

Should do it.
