I noted on the Ubuntu 23.10 release announcements, a link to upgrading early was provided via https://help.ubuntu.com/community/ManticUpgrades

I also notice on the Ubuntu Mantic Minotaur (23.10) Release Status Tracking that it's still in progress.

I forced upgrade using the ManticUpgrades link (using -d), is anything missing in my early upgraded system?

Background

My normal process for writing ISOs is downloading them (zsync via script which performs a ISO validation & shows me the package changes (ie. manifest diff from prior download)), then use mkusb to write it to thumb-drive, eg.

guiverc@d7050-next:/de2900/lubuntu_64$ sudo mkusb-nox mantic-desktop-amd64.iso all

I then quickly scan messages & if it looks good, eject the thumb-drive, and boot it on a nearby box & confirm media write there using a method documented here, ie.

  • boot it in try mode, and wait awhile to let background media validation occur, scanning the systemd journal using

sudo journalctl |grep casper-md5check

watching for

May 11 08:37:47 ubuntu casper-md5check[3924]: Checking ./boot/grub/loopback.cfg...../boot/grub/loopback.cfg: OK
May 11 08:37:47 ubuntu casper-md5check[3924]: Check finished: no errors found.
May 11 08:37:47 ubuntu systemd[1]: Finished casper-md5check.service - casper-md5check Verify Live ISO checksums.

This validation I believe is essential, as I find 5-8% of ISO writes fail regardless of the hardware being used (ie. different boxes & different thumb-drives).

Question

Can I validate the ISO write using an easy tool, using the same box I used to write it (ie. no reboot or nearby box necessary).

My preference is terminal; as it's where I am for these tasks.
