Debian 12.6 nopubkey error while apt update can't update sources

[ELDebiano]

this all started when atempting to apt update ; apt upgrade while opening firefox at the same time with 6 or 7 tabs at once and while recording audio too on audacity all on this micro sd 64GB card inserted in the built-in micro sd slot on my netbook celeron N4000 with 4GB of ram 2400mhz when it probably needed 8GB of ram and a faster write block device with proper write speed.

Here is a photograph the micro sd card, binary and ascii keyrings on their respective directoris to show you they're correctly installed. and the apt update failur error mesage:


basicaly i want to be able to update debian, the packages might also need to be reinstalled, packages like debsums and mailcap

You can see percentage of filling of storages/disks by df command.
When was the last time (before this attempt) that you ran the apt update command?
Please, can you copy these photographed messages here (enclosed in code tags, which can be done by selecting text and clicking on black icon of terminal with text </>: above text area of entered text)?

[ELDebiano]

df shows 5 mount points are mounted
/dev
/run
/ [is 56% used for, the rest is using 1% or 0%]
/dev/shm
/run/lock

/home is not mounted because linux boots into emergency mode.

if is not the available space being low which i didn't think it was, why there is not a public key or unable to run apt-get update?

UPDATE:I forced fs check and it discovered errors which I manually fixed by pressing y on every question.
tried apt update again but still fails with slightly diferent errors still segmentation fault issues not sure if post-instalation script subproces error as well or not.
-I'm reinstalling debian 12.6 as of now.

Hello,

UPDATE:I forced fs check and it discovered errors which I manually fixed by pressing y on every question.
tried apt update again but still fails with slightly diferent errors still segmentation fault issues not sure if post-instalation script subproces error as well or not. -I'm reinstalling debian 12.6 as of now.

Have you sorted it out ?

[ELDebiano]

yes I sorted it out few days ago, reinstalled debian MATE on top of the XFCE corrupted debian, no issues with inter twined config files as I used the same home directories even same directory for the users which i put the same names and same folders.

I think i could had fix it in XFCE if i done another forced check on root and home partitions. I didn't know forced e2fsck could help a lot.
recently upgraded to 12.7 doing a dist-upgrade.

I should add that siena mirrors are offline so double the damage.
