imapserver.acquireconnection(): <class 'TypeError'> - cannot use a bytes pattern on a string-like object

I'm getting this error using Python3 from Archlinux, what could it be?

Logs, error

Quite possible. We don't support Py3.

[rizzopablo]

Oh... Ok

I uninstalled imaplib2 and now the error is this:

Ok, thanks for the report.

Notice you're still running offlineimap with python3.

[nicolas33]

You might like to remove this version of offlineimap since this was installed using pip for python 3.

[rizzopablo]

I'm now running it with py2 and works great, but I'm on a py3 project and would need to run offlineimap with the same python version.
Thanks!

[nicolas33]

This would require to support py3 in the first place. So, this is currently not possible. I'm not sure this day will come for offlineimap. We tried to support py3 but we stopped. That's why I introduced imapfw but it's still in a very early development stage.

[ff2000]

Was there some progress regarding py3 support? Py2 will be unsupported in less than 1 month. As imapfw never really took off having py3 support in OfflineImap would be really needed.

[nicolas33]

No, there was no progress regarding py3 support. I'll make the announce about this before the end of the year.

The short story is:

1. I still intend to contribute to imapfw but I lacking free time curently mostly because my family is growing.
2. I don't think offlineimap will ever be ported while contributions are welcome.
3. I'll continue to maintain offlineimap during months after the py2 (edited) end of life.

Hello @ff2000 and @rizzopablo
If you, or your organization/company, would like to explore the possibility to sponsor the development of a port to Python3 of classic offlineimap, and/or to sponsor the ongoing development of the new next-generation IMAPfw software which is designed for Python3, then please click on the "Sponsor" button, at the top of this page, and consider becoming a Backer (only $5/month), or consider your company becoming a Sponsor (only $100/month)!

More exciting benefits include: your organization's/company's logo and social media page mentioned in the official OfflineIMAP social media, and in the software's official release notes!

Hi,

IMO, this issue should be closed and merged with #670
