Upgrading from 3.0.2.8 to 3.0.3.10 on an Aigo tablet fails

[Olf0]

Original report at OpenRepos by @dalas_revo:
"Unfortunately upgrading from 3.0.2.8 to 3.0.3.10 on the Aigo (Jolla Tablet) fails for me with sfos-upgrade, complaining about a missing /sys/class/power_supply/battery/uevent."

I might introduce an override for this after some more analysis:

• Sounds, as if that did not happen during earlier upgrades of SailfishOS with sfos-upgrade on your Aigo tablet, or was upgrading from 3.0.2.8 to 3.0.3.10 the first use of sfos-upgrade on your Aigo?
• What is the output of the following commands (as root) on this device?
  1. mount | fgrep sysfs
  2. ls -l /sys/class/power_supply
  3. ls -l /sys/class/power_supply/battery
  4. cat /sys/class/power_supply/battery/uevent

Checking the battery charge is important, thus I want to avoid implementing an override, if a proper solution can be introduced.

Hi,

it was indeed the first time for the Aigo, I only used your tool on the XA2 before. Not sure whether I can help, as things might have changed between 3.0.2.8 and 3.0.3.10, which is my current version (I used the version --dup-way). If I need to downgrade to help analyzing: can I set ssu re 3.0.2.8 and use version --dup?

Anyway, on 3.0.3.10 the outputs are:

mount | fgrep sysfs

none on /sys type sysfs (rw,relatime)
none on /opt/alien/sys type sysfs (rw,relatime)

ls -l /sys/class/power_supply

cat /sys/class/power_supply/battery/uevent

Not sure if I understand correctly what information you need, but as you can see above there is no

/sys/class/power_supply/battery

but there is a

/sys/class/power_supply/dollar_cove_battery

and there is a

uevent

inside.

cat /sys/class/power_supply/dollar_cove_battery/uevent outputs

Does this help?

a. Do not downgrade! While that may work under specific circumstances, any downgrade which affects more than the last version field ("point release") may result in an unusable SailfishOS installation (and downgrading over a stop release will almost certainly do that).
For details, see: https://together.jolla.com/question/50986/howto-how-to-revert-to-an-earlier-sailfish-os-version/?answer=51003#post-id-51003

b. Thanks, this is all the information I need to employ a proper solution.

[dalasre]

Well, as the information is sufficient, I won't try downgrading ;)

[Olf0]

A draft of a solution has been implemented in PR #27.

[Olf0]

This is resolved in the v3.1 (currently "pre-") release.

Can you please issue these commands on your Aigo tablet:

cd /tmp
curl -LO https://github.com/Olf0/sfos-upgrade/releases/download/3.1-1/sfos-upgrade-3.1-1.noarch.rpm
devel-su
pkcon install-local sfos-upgrade-3.1-1.noarch.rpm
sfos-upgrade "$(version | rev | cut -s -f 2 -d ' ' | rev)"

See, if sfos-upgrade performs the battery checks (even if a check proper fails, this is fine, as long as sfos-upgrade now successfully manages to extract the battery information) and answer with "n", when ultimately asked, if you want to perform the upgrade.
Side note: Actually this would perform a "same-grade", as the command above instructs sfos-upgrade to "upgrade" to the installed version; hence it does do no harm, if you accidentally answer with "y" (but all Patchmanager Patches are unapplied then; still you should not interrupt sfos-upgrade, if that happens).

[Olf0]

@dalasre et al, if you still see issues extracting the battery information with sfos-upgrade 3.1 or later, please post here.
Note that v3.1-3 was published on OpenRepos today, so you can update to it per GUI.

"Re-fixed" this issue in sfos-upgrade 0.3.5.
