undefined method `uidvalidity'

[julpec]

When migrating, I have this error reported :

append error: undefined method `uidvalidity'

I did what @maty974 did in #140 renaming the ruby library file and there is no error reported.

Hi @julpec

Thanks for opening this issue.

Please run the following commands and send me the output:

ruby -v

command -v imap-backup

bundle show

bundle show net-imap

[julpec]

# ruby -v
ruby 2.7.4p191 (2021-07-07 revision a21a3b7d23) [x86_64-linux-gnu]

# bundle show
-bash: bundle : command not found

# command -v imap-backup
/usr/local/bin/imap-backup

# imap-backup -v
imap-backup 12.1.0

Ah, sorry, you aren't using Bundler, so you won't have bundle.

Could you show me the output of this:

gem list

There should be an entry for net-imap, probably net-imap (0.3.7)

Thanks @julpec

Please send me the full output you're getting when you run migrate.

[joeyates]

By the way, a quick fix for your problem would be to update Ruby — you're using version 2.7.4, which is quite old. Is that possible in your case?

[joeyates]

@julpec Any updates on this?

[julpec]

I was able to migrate without any errors. I can't test again as I no longer have access to the old mailboxes. Btw, thank you for this utility and for the support.
