sudo apt-add-repository universe sudo apt-get update sudo apt-get install ayatana-webmail
and will work great after setup, but its icon in tray is not pretty:
For better integration we need additional package named Ayatana Indicator Messages, but it is not available in Ubuntu repositories (it is a bug 1916378).
As a workaround one can use my PPA as follows:
sudo add-apt-repository ppa:nrbrtx/aym sudo apt-get update sudo apt-get install ayatana-indicator-messages sudo apt-get dist-upgrade
and after reboot you will get pretty Ayatana Indicator Messages in place:
Notes and known issues. For some reason or maybe some issue Ayatana WebMail Preferences (
ayatana-webmail-settings) can't be run on second time when Ayatana Indicator Messages is enabled.
So to configure second e-mail account one should purge my PPA by
sudo apt-get install ppa-purge sudo ppa-purge ppa:nrbrtx/aym
and then open Ayatana WebMail Preferences from its icon using Settings option on top bar. Then when e-mail account setup is finished, then one can re-add the PPA to get Ayatana Indicator Messages back.
