Debian Dog - snapd install

[dcung]

I am testing on few old laptops.
Using Bullseye DDOG (with systemd -> snapd requires systemd).
All frugal fresh install - from latest ISO made recently.

I got these errors on an old Toshiba Tecra M5 (T7200, 4GB Ram).

Code: Select all

root@live:~# apt update

E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

But on an old Dell D630 (T8300, 4GB Ram), and also other laptops (Lenovo), this does not happen.
snapd installed okay without errors.

1. Why?
2. How to fix it pls?

@dcung Looking at your output, this:
Get:6 https://github.com/doglinux/bulldog/raw/master/amd64 ./ InRelease [2,301 B]
Indicates for me that your build is not with systemd, if it was, it would make use of:
https://github.com/doglinux/bullseye/raw/master/amd64 (is without elogind, eudev, ( for systemd build ))
edit: test, if this: pidof systemd gives output, then indicates that you are running with systemd.

You're absolutely right!

pidof systemd gives no output.
So, I re-copied the frugal install again (really paying attention this time ) and it works.
I must have copied the wrong one on this laptop earlier.

Sorry and thank you, Fred.

I have been looking for a 'light-weight' linux viewer to add to my camera manufacturer's software (i.e. Windows only).

The reason I was trying to install systemd was that I came across this (requires snapd systemd)
https://snapcraft.io/install/cctv-viewer/debian
and I was testing it on few different laptops and its CPU impact on each of the old laptops I have (ended up testing on 5 old laptops).

While 'multi tasking', I thought, what if I install it on old laptops with 'native' nvidia driver instead of generic driver. What difference would it make to CPU util. Hence the older Debian Dogs came to mind to test it with.

Anyway, I 'abandon' older DDogs now. Or at least, no longer a priority.
I already got the results of all 5 laptops before I managed to sort out (systemd/snapd/nvidia driver) of 2 laptops with nvidia GPU.

With Bullseye and generic driver, all 5 laptops are smooth and easy installs.
(with exception of my dumb mis-copy on Tecra above).

4 laptops have CPU utils 35-50% (T5600, T7200, T7500, T8300), and 95-100% for Atom N450 CPU.

So, with these results, I don't think I would bother with nvidia drivers.
BTW - These are with 3 cameras viewing.
