imap-backup do not start on Ubuntu 22.04

[Rudiberto]

I'm messed up.
When I updated to Ubuntu 22.04 (Mint 21) my imap-backup stopped to work. At first, I downloaded the last version from here, then I installed the last version of imap-backup using "gem install". ERRORS
Then I uninstalled all up to ruby on my pc, deleted manually all old versions of gem in all folders and began a clean installation of ruby.
But after all: Starting imap-backup I'm still receiving this horror list of error messages

imap-backup worked properly for nearly a year on this pc and now such a mess. All the folder exist. When I'm starting imap-backup with sudo, the list is a lot shorter:

sudo imap-backup /var/lib/gems/3.0.0/gems/imap-backup-8.0.1/lib/imap/backup/cli/helpers.rb:68:in load_config': Configuration file '/root/.imap-backup/config.json' not found (Imap::Backup::ConfigurationNotFound)

Here is the only thing I understand: The json config file is not there, because it is in my home folder, of course. When I copied the whole .imap-backup-Folder to root-Folder, it worked right away and transformed all boxes metadata to the Version 3 Format.
Does that mean, that from now on, I have to execute imap-backup with sudo rights and configuration file stored in root-Folder?
That's not good for my needs. Don't like to execute usual programs in root mode. Also don't like to make a user-install into my home folder.
What is to do, to have the former behavior back?

Hi @Rudiberto

Thanks for reporting this issue.

It is caused by release 2.8.0 of the 'mail' gem.

Here's the GitHub issue.

There's no need to switch to running imap-backup as root.

As a quick fix, you can do this:

sudo chmod o+r /var/lib/gems/3.0.0/gems/mail-2.8.0/lib/*.rb

I'll release an update to imap-backup with a fix later today.

[joeyates]

I've released version 8.0.2.

@Rudiberto, let me know whether it fixes your problem.

[Rudiberto]

Seems to work great! Thx a lot!
At first, it seems not to work - had the certificate hash running over the screen and stopped it - but the second intent worked fine. After a reboot, it's still well.
Great job! Thank you for your great and REALLY fast reply.

[joeyates]

Glad that's sorted out!
