Unable to upgrade from Mint 21.3 to Mint 22

[Mr-Green-Genes]

I have a Starlabs Byte II (small desktop device, not portable) which came preloaded with Mint 21.3. I started the process of upgrading to Mint 22 but hit a brick wall. I had a message which said "Connect the computer to a power source ..." and wouldn't go any further. Using acpi -a returns Adapter 0: off-line, acpi -b gives Battery 0: Discharging, 0% and hostnamectl chassis returns desktop.

What is going on here please and how can I fix it?

mintupgrade runs acpi -a and a return value containing "off-line" causes the error.

However, a Starlabs Byte II claims it comes with a 36W power adaptor - which (if true) would act like a battery charger on a laptop?

[Mr-Green-Genes]

Yes, it does have a power adapter like a laptop. So is acpi -a returning "off line" a BIOS issue?

Hi, I have the same problem. I am using a mini desktop too. Same error message. "Connect the computer to a power source ..."

hostnamectl shows Chassis: desktop
acpi -a returns Adapter 0: off-line
acpi -b returns nothing

I have bypassed the mintupgrade check by setting the 'check.result' in the mintmupgrade.py to 'RESULT_SUCCESS' and the upgrade worked, BUT it installed Mint22 like a laptop and the power management showed that the computer is running on battery, which does not exist.

I am running on Mint21.3 Kernel: Linux 5.15.0-117-generic I have upgraded to Kernel 6.8.039. The result was that the computer did not power off after shutting down Mint.

I hope someone has an idea what to do.
Does it make sense to open another bug on the same issue ?

Definitely worth opening as an issue if it consistently doesn't power off.

[Jeremy7701]

Does entering sudo shutdown now in a terminal do anything?

[Mr-Green-Genes]

I think this should be directed to #105. I do not have that issue as I am still on Mint 21.3 and Kernel 6.5.0-45-generic and can shut down ok.

[GPard1009]

have tried sudo shutdown -P and the result was the same. Linux does shut down but it does not power off.

I have tried it a several times also with sudo shutdown now

With 5.15.0-118-generic there is no problem, the computer does power off

Here something for the update problem. I have installed 21.3 on the same computer in a VM (Virtual Box) and mintupgrade does not find a connected powersupply.

Updating this VM to 6.8.0.39 shows no problem to 'power off' ok. its not really the same thing.

[Jeremy7701]

The problem is that mintupgrade runs 'acpi -a' and checks that the output does not include the string "off-line".
Since its essential that laptops are plugged in, it seems unlikely that this will be disabled.

I'd suggest one of two possible workrounds if you want to edit a system program:-
Obviously I haven't tried testing these.
You might like to try this out in a VM first.

1. Locate where mintupgrade runs 'acpi -a' and change it to run 'acpi -v'
   An appropriate location appears to be line 184 of /usr/lib/linuxmint/mintupgrade/checks.py
   Alternatively...
2. Compile any C "hello, world" program as /usr/bin/acpi and do not change mintupgrade.
   Reinstall acpi afterwards, if you should take this course.
