I shifted from Windows 8 to ubuntu about 3 weeks ago. I have to experience very slow booting. I don't have a dual boot or something else. Plus I have tried to clean install ubuntu but nothing changed by it. My PC is Lenovo 15-ay542tu with 8gb ram and 1TB HDD.

I use android studio so should I disable libvirtd ?
– Parag Katoch Aug 20 '20 at 07:01journalctl –vacuum-size=500M. You could still try disablinglibvirtdfrom automatically starting on boot, and then startlibvirtdwhen you need android studio, for example:sudo systemctl start libvirtd. – jksinton Aug 20 '20 at 11:3647.289s plymouth-quit-wait.service 16.859s apport-autoreport.service 15.857s snapd.service 13.820s NetworkManager-wait-online.service 13.183s networkd-dispatcher.service 12.114s dev-sda2.device 12.111s fwupd.service 8.771s udisks2.service 7.889s accounts-daemon.service– Parag Katoch Aug 20 '20 at 13:42NetworkManager-wait-online.serviceusing this guide. – jksinton Aug 20 '20 at 14:05
