After L4T 36.4.7 upgrade from 36.4.3, i see 3 different jetpack in my machine, how to fix?

Hi all,
i am lost as i try to understand what is happening in my Nano super (flashed with jetpack 6.2)

Here is what i did:
i had the L4T 36.4.3 installed as well as the jetpack 6.2.
i had the (bad) idea to make an apt upgrade, thinking i will have the latest release to run my app.

Now when i look at the installed jetpack, i got 3 version installed:
6.2.1+b38
6.2+b77
6.1+b123
and the booloader shows L4T 36.4.7 ? (36.4.4 was expected and mentioned in the documentation)

i believe this is not ok and i cant find anything to fix this!
also i have seen ā€œjetpack missingā€ in jtop after upgradingā€¦

please, help me to fix this, i spent 2 weeks trying to make this unit ready before installing my app.
At least, i want to understand what is happening here.
thanks a lot

this topic you mentioned refers to the AGX Orin, is it related to Orin Nano too?
and why it shows 3 versions of jetpack installed? is there a way to remove the old ones?
thx

Hi

Yes.

Please provide your commands for us to check since we only see one version installed on our side.

apt list --installed nvidia-jetpack -a
Listing... Done
nvidia-jetpack/stable,now 6.2.1+b38 arm64 [installed]
nvidia-jetpack/stable 6.2+b77 arm64
nvidia-jetpack/stable 6.1+b123 arm64

ok for the AGX/nano has the same security fix version (i also own an AGX, good to know, thx)

what i got with this command lineā€¦
apt list --installed nvidia-jetpack -a
Listingā€¦ Done

and nothing more!?ā€¦ how is this possible?

when i do apt-cache show nvidia-l4t-core, i got:
ā€¦
version: 36.4.7-2025ā€¦
ā€¦
version: 36.4.4-ā€¦.
ā€¦
version:36.4.3-ā€¦

is this possible the apt list doesnt show any version?

when i open the file nv_tegra_release:
R36 (release), REVISION: 4.7,ā€¦.

Should i mention that i flash the device using and SD card? dont know if this is important here, regarding the result of the command line

for Jtop error, showing missing jetpack, you must know that jetson_stats is not up-to-date, at this time, regarding the 36.4.7 /JP6.2.1 you mentioned.

there is an easy fix for that, if you dont want to wait for an update:

following this, you may add the corresponding lines and change the jtop version to 4.3.4 for ā€œ36.4.7ā€: ā€œ6.2.1 (rev1)ā€.

hope that helps.
for the multiple versions of jetpack showing up, i donā€™t know, maybe someone else will explain this situation as well as the empy result of the command line apt list --installed nvidia-jetpack -a

Hi,

What is your result after running below commands?

sudo apt update
sudo apt install nvidia-jetpack

Thanks

Hi,
the result of apt update gives ā€œall packages are up to dateā€
the result of install jetpack gives"ā€¦ 25 newly installedā€¦" but i didnt proceed yetā€¦

the strange thing is that i got Jetpack infos in Jtop, so jetpack must be installed on this machineā€¦ also why i got 3 nvidia-jetpack listed after apt-cache show nvidia-jetpack?

should i proceed the install again as you suggested? thx for your answer

hi,
you can proceed without any doubt, you should finally see the installed jetpack, using the command line apt list --installed nvidia-jetpack -a

your system must be now fully updated, ready to run your apps
