Comment 12 for bug 1898869

erm ...

this is an atom/celeron laptop with 4GB that starts BOINC as a system service during boot ?

there seems to also be a lot of broken gnome-shell extensions installed on this system that error out during startup ...

there is ifupdown installed which is probably involved with the network manager slowness (was this an upgrade from a former LTS ? (ifupdown is deprecated since years now and should not be installed at all) ...

have you ever tried a plain unmodified 20.04.1 on this machine without installing all this extra software on top ?
