I had a working installation under Ubuntu 18.04 and upgraded the distro to 20.04.2.  Now I'm unable to access any mail with Sogo (Roundcube is not installed).  The basic error seems to be the following:

Feb 01 23:32:42 sogod [3010]: <0x55d51210fbc0[SOGoMailAccount]:0> renewing imap4 password

I'm not opposed to wiping the whole installation and starting from scratch with a fresh install of Ubuntu / iredmail other than that I would like to preserve the emails if possible.  Any help would be appreciated.
