Current Linux Kernel that you run is what matters and there is no difference (upgrade through GUI from now on will provide as well better user experience from day to day … for example having phosh 0.15.0-1pureos2 as already available, etc.), therefore only if you will proceed as I wrote down inside of post my #116. I think that there is some advantage of executing: sudo apt upgrade linux-image-librem5, before: sudo apt upgrade, as general CLI command that calls for all upgrades at once (for overview use: sudo apt list --upgradable). And that removing of all unnecessary Linux Kernels (like linux-image-5.15.0-1-librem5) helps greatly to gain significant amount of free “room” within /boot partition:
And, related to myself, as long as we have had Purism Staff involved here (and still have) I felt safe (and confident) as well (not to make any unnecessary mistake). Thank you all, especially to @mladen, @joao.azevedo and @dos!
EDIT: For example executing of:
Should give you the following output:
linux-image-5.16.0-1-librem5/byzantium in version 5.16.3pureos1 and this confirms to myself that versions of 5.16.2pureos1 (second one) and 5.16.1pureos1 (first one) already belong to previous apt upgrade. Simply put it is up to you to decide what to do, my thought was that that older linux-image-5.15.0-1-librem5/byzantium plays just static role within /boot, just by looking at its install date, as you posted it:
Here are already advices not to rush into anything, including official one from @joao.azevedo, so no need … my recommendation was just my opinion, nothing that matters any more as of now, as of you run your Librem 5 as expected.
