Is there any tutorial to update roundcube? I am still on v1.3.17, Apache only ISPC install. I tried this one https://www.taste-of-it.de/ispconfig-server-panel-update-von-roundcube/ replacing the version numbers with 1.6.0, everything seemed to go ok in the terminal, just got the dreaded "Oops... something went wrong!" after.
https://forum.howtoforge.com/threads/add-roundcube-to-old-perfect-install.83936/#post-400465 just change the version numbers as appropriate. this was written quite a while ago, as far as i'm aware, this process should still work without issue, but be aware you may need to make some tweaks.
