dnf5 offline-upgrade fails with toml error(s)

[sebastiaanfranken]

On Fedora 42/Rawhide running dnf offline-upgrade download -y works as it should and downloads any updates. The next step dnf offline-upgrade reboot fails with a DNF5/toml error:

Error reading state: [error] toml::parse_file: invalid table key
 --> /usr/lib/sysimage/libdnf5/offline/offline-transaction-state.toml
   |
 1 | [
   |  ^-- expected basic key([a-zA-Z0-9_-]) or quoted key(" or ')
. Rerun the command you used to initiate the offline transaction, e.g. `dnf5 system-upgrade download [OPTIONS]`.

Which appears related to #1186 . The toml file mentioned (/usr/lib/sysimages/libdnf5/offline/offline-transaction-state.toml) has the following:

[
    "offline-transaction-state",
    {module_platform_id = "", poweroff_after = false, verb = "upgrade", system_releasever = "rawhide", target_releasever = "rawhide", cachedir = "/var/cache/libdnf5", status = "download-complete", cmd_line = "dnf offline-upgrade download -y", state_version = 1},
]

Duplicate of #1693.

@ppisar Closing this was maybe a tad fast, since #1693 and #1694 don't actually fix it, it started happennig for me 3 days ago, while both references issues are marked as solved 5 or so days ago. So far I've been applying updates the old fashioned way with sudo dnf upgrade, but that hasn't fixed it. Or is this a Fedora packaging issue and I'm barking up the wrong tree?

I dare to say you are using old DNF5: You reported an issue in 5.2.6.0. Then #1694 fixed with b8fbbb1 commit. Then 5.2.6.1 was released. Then 5.2.6.1 was built in Fedora 42 on 2024-09-20.

This issue tracker tracks a developmental code here on GitHub. Once it is fixed in GitHub repository, the issue is closed here. If you want tracking issues from Fedora point of view, you need to use Fedora's Bugzilla.

Something odd was going on in that case, since the latest update (yesterday, for this machine) pulled in a update to dnf5 (libdnf5) version 5.2.6.2 which indeed fixed this. Thanks for the assist.
