I have a server runing debian jessie 8.11 and ISPConfig 3.1.12 with a few domains. My server is running Roundcube Webmail 1.1.5
I'm trying to upgrade to debian 9 (Stretch) with this simple guide https://www.howtoforge.com/tutorial/how-to-upgrade-debian-8-jessie-to-9-stretch/
Everything goes ok except roundcube; when I put the apt-get dist-upgrade command with sources.list of "stretch"; in the upgrade process the installer says that needs to update the roundcube database but fails the process with the following error:
Quotemysqldump: Couldn't execute 'SHOW FUNCTION STATUS WHERE Db = 'roundcube'': Cannot load from mysql.proc. The table is probably corrupted (1728)
Any ideas??
Thanks in advance
