Bug#954742: evolution: Error performing TLS handshake: A packet with illegal or unsupported version was received.

[Hatem Masmoudi]

Hello,

After some analysis, it look like TLS1.0 and TLS 1.1 where disabled through glib-networking starting from version 2.64.x (https://gitlab.gnome.org/GNOME/glib-networking/-/commit/0f5938dbc7ac92913673c102b5707675ca8a0eb9)

As a workaround is to execute evolution as the following : > export G_TLS_GNUTLS_PRIORITY="NORMAL:%COMPAT:+VERS-TLS1.0" ; evolution

Best regard,
Hatem Masmoudi
