[SOLVED] Upgrading Debian in a live CD

hd_scania · 11-15-2017, 04:11 AM

By every time my Parabola system has experienced errors before entering my graphical shell I always remember my live ISO, running pacstrap and arch-chroot commands, under them full upgrading my whole system, and finally my Parabola system is recovered.
For deb systems, like Trisquel, Debian, Devuan, what are the possible commands correspondent to pacstrap and arch-chroot, to help to rescue my deb systems?
I have already tested the chroot command which NetworkManager is not working at all, even reinstalling NetworkManager packages in dpkg not working, which I need to look for the possibly alternative commands which are surely working.

You can't upgrade a 'live' CD, you will need to remaster it.

I actually stand this for, running commands from a Debian live system for upgrading my local deb systems, I am not touching software packages from the live session, but using a live system to upgrade hence revive the local systems. This works well for a pacman system like Parabola, now doing the same for deb systems.

After a rescue for my system the above error was occured, even after fixing the apt and NetworkManager packages and some deps using dpkg. What to do now?

Is the network working? ping -c2 lq.org
(If not, can you manually bring it up?)
(Or maybe I don't understand the situation; if so, my apology)

My NetworkManager is surely working, but somewhy dead for apt and web browsers.

Hmmmm..... Interesting

Maybe double-check what I'm thinking here...

Is it DNS that's broke? /etc/resolv.conf (now a magic link to systemd's /run

)

So, you can ping -c2 security.debian.org, immediately before apt command?
IF not, we need to dig up the tricks about fixing above resolv,
(assuming a ping of Satanic 8.8.8.8 works)
which I've recently seen several places. Oh, solut'n is DevuanSlack*

IF yes, try sudo on the ping, as an insane sanity check.

Or, IF only 'web' stuff, is some ufw firewall (which Idk) blocking?
Try wget (subdom. deb or lq .org)
and/or nslookup/dig, to try wget by IP #.#.#.#

Setting /etc/resolv.conf to 8.8.8.8 (the Lucifer's IP) works to revive apt and my web browsers, and I have upgraded and afterwards installed maps like Marble-noK and qGIS.

WtX they are??? subdom.deb seems to be nothing and also lq.org is redirected to LifeQuest, a clinical centre in Pennsylvania.

My last issue is, I find the below startup command (manually) annoying,

Code:

sudo mount /dev/sda14 / -o rw,remount && sudo nano /etc/resolv.conf && sudo sddm

But I have appended Qubes and Subgraph into the Debian system, how to prevent from this anymore?
