I ran gparted and the Ubuntu disk utility as well as fdisk, sfdisk, cfdisk and there is no swap partition that I can find. There are tens if not more files listed w/ fdisk and the following is running lsblk There are obviously significant changes in 20.04 that are pretty much incomprehensible to me! $ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT loop0 7:0 0 161.4M 1 loop /snap/gnome-3-28-1804/128 loop1 7:1 0 105.2M 1 loop /snap/audacity/648 loop2 7:2 0 154.3M 1 loop /snap/chromium/1143 loop3 7:3 0 156.2M 1 loop /snap/chromium/1165 loop4 7:4 0 97M 1 loop /snap/core/9289 loop5 7:5 0 93.9M 1 loop /snap/core/9066 loop6 7:6 0 55M 1 loop /snap/core18/1705 loop7 7:7 0 289.8M 1 loop /snap/kde-frameworks-5-qt-5-14-core18/3 loop8 7:8 0 55M 1 loop /snap/core18/1754 loop9 7:9 0 140.7M 1 loop /snap/gnome-3-26-1604/100 loop11 7:11 0 49.8M 1 loop /snap/snap-store/454 loop12 7:12 0 255.6M 1 loop /snap/gnome-3-34-1804/33 loop13 7:13 0 107M 1 loop /snap/gnucash-jz/43 loop14 7:14 0 255.6M 1 loop /snap/gnome-3-34-1804/36 loop15 7:15 0 54.8M 1 loop /snap/gtk-common-themes/1502 loop16 7:16 0 181.1M 1 loop /snap/spotify/36 loop17 7:17 0 141.8M 1 loop /snap/inkscape/7601 loop18 7:18 0 62.1M 1 loop /snap/gtk-common-themes/1506 loop19 7:19 0 140.7M 1 loop /snap/gnome-3-26-1604/98 loop20 7:20 0 260.7M 1 loop /snap/kde-frameworks-5-core18/32 loop21 7:21 0 160.2M 1 loop /snap/gnome-3-28-1804/116 loop22 7:22 0 87.8M 1 loop /snap/kdenlive/23 loop23 7:23 0 132K 1 loop /snap/gtk2-common-themes/9 loop24 7:24 0 141.8M 1 loop /snap/inkscape/7627 loop25 7:25 0 132K 1 loop /snap/gtk2-common-themes/5 loop26 7:26 0 291M 1 loop /snap/vlc/1620 loop27 7:27 0 163.7M 1 loop /snap/spotify/41 loop28 7:28 0 2.2M 1 loop /snap/gnome-system-monitor/148 loop29 7:29 0 290.6M 1 loop /snap/kde-frameworks-5-qt-5-14-core18/4 loop30 7:30 0 2.2M 1 loop /snap/gnome-system-monitor/145 loop31 7:31 0 202.9M 1 loop /snap/vlc/1397 loop32 7:32 0 87.8M 1 loop /snap/kdenlive/24 loop33 7:33 0 113.4M 1 loop /snap/audacity/666 sda 8:0 0 238.5G 0 disk ├─sda1 8:1 0 512M 0 part /boot/efi └─sda2 8:2 0 238G 0 part / However I get this when I run the following so Swap is not a partition, right? What is it now? A file as you noted? $ grep SwapTotal /proc/meminfo SwapTotal: 2097148 kB Thanks so much Ted and I hope that you are doing as well as you can be.
