dmesg prints a large log that I cannot copy, the only red lines I read regard bluetooth, but the log is huge and I can only see a fraction of it.

I can cd to /var/log and ls it, what file do I have to open? or what do I do now?

after trying suggested command

sudo dpkg --configure -a

I get:

error processing package install-info (–configure): installed install-info package post-installation script subprocess returned error exit status 127, errors were encountered while processing install-info

in recovery mode as root I executed:

mount -o remount,rw /

mount --all

then cd’ed to /media/home, ls’ed and got no results.

I also don’t know if changes to make the system writable are made on the go or if I have to reboot. I rebooted and the system is still in read only mode.

ETA: another command that might be relevant:

dpkg --configure -a

returns

error processing package install-info (–configure), installed install-info package post installation script subprocess returned error exit status 127

it seems there is no -a option for dpkg-reconfigure:

sudo dpkg-reconfigure -a returns unknown option -a

if I delete -a it asks for a package to reconfigure

If you’re gonna use Linux then go ahead and replace the battery so that you’re not worrying about it failing miserably to communicate with the charge controller or battery itself and tell you when telhe thing is fucked and need replacing.

I’m already using linux, macos was nuked.

I don’t understand this paragraph. Do you mean new batteries for this model (macbook pro from 2014) work better with linux?

just to be clear, you mean removing the battery, or do you mean using a command?

backup done

/etc/apt/sources.list point to 24.04 noble

there are 2 packages disabled on upgrade to noble: mkv and imagereader, lines are commented so nothing wrong here

do you still recommend to execute sudo dpkg-reconfigure -a?

The most important part with batteries is to check if they start swelling up.

do you mean physically swell up? like I’m going to see it bent/bigger?

When MacBooks are plugged in, they get their power from the charger. They are not simultaneously draining and charging the battery in general.

so when the battery is fully loaded a controller tells the mobo to stop loading the battery and to use power from the charger to simply power the notebook, is this so?

this is what sudo tlp-stat -b prints:

do you still recommend a new battery?
