Thank you for reporting this bug to Ubuntu. Ubuntu 21.10 (impish) reached end-of-life on July 14, 2022. Ubuntu 21.04 (hirsute) reached end-of-life on January 20, 2022.
See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases Ubuntu 21.04 was not a LTS release; had one supported & quality- assurance tested upgrade path; to Ubuntu 21.10 or the next release; which closed the moment Ubuntu 21.10 reached EOL. The upgrade path you're trying to use is not supported. Use a LTS or long-term-support release if you don't wish to release- upgrade every 6-9 months. Ubuntu 21.04 told you it was the 2021-April release (ie. a year.month format is used with 2000 added to year) meaning the 9 months supported life is pretty easy to calculate & thus plan. If using a LTS release you have had 2-5 years and not 6-9 months which is generally better for most users (eg. 20.04 LTS or the 2020-April release has support until 2025-April for standard support; which can be extended via use of ESM too) ** Changed in: linux (Ubuntu) Status: Confirmed => Invalid ** Package changed: linux (Ubuntu) => ubuntu-release-upgrader (Ubuntu) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1981939 Title: sudo do-release-upgrade Status in ubuntu-release-upgrader package in Ubuntu: Invalid Bug description: Hello, Distributor ID: Ubuntu Description: Ubuntu 21.04 Release: 21.04 Codename: hirsute By using the command "sudo do-release-upgrade" i was expecting my server upgrading from Ubuntu 21.04 (Hirsute) to 22.04 (Jammy Jellyfish), but the following error shew up : " Reading cache Checking package manager Can not upgrade An upgrade from 'hirsute' to 'jammy' is not supported with this tool. === Command detached from window (Sun Jul 17 20:12:08 2022) === " Cordially, Nathan ProblemType: Bug DistroRelease: Ubuntu 21.04 Package: linux-image-5.11.0-49-generic 5.11.0-49.55 ProcVersionSignature: Ubuntu 5.11.0-49.55-generic 5.11.22 Uname: Linux 5.11.0-49-generic x86_64 AlsaDevices: total 0 crw-rw---- 1 root audio 116, 1 Jul 17 19:24 seq crw-rw---- 1 root audio 116, 33 Jul 17 19:24 timer AplayDevices: Error: [Errno 2] No such file or directory: 'aplay' ApportVersion: 2.20.11-0ubuntu65.4 Architecture: amd64 ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord' AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: CRDA: N/A CasperMD5CheckResult: unknown Date: Sun Jul 17 20:10:28 2022 Ec2AMI: ami-0002e2be Ec2AMIManifest: FIXME Ec2AvailabilityZone: nova Ec2InstanceType: vps2020-comfort-4-16-80 Ec2Kernel: unavailable Ec2Ramdisk: unavailable IwConfig: Error: [Errno 2] No such file or directory: 'iwconfig' Lsusb: Bus 001 Device 002: ID 0627:0001 Adomax Technology Co., Ltd QEMU USB Tablet Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Lsusb-t: /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M |__ Port 1: Dev 2, If 0, Class=Human Interface Device, Driver=usbhid, 12M MachineType: OpenStack Foundation OpenStack Nova PciMultimedia: ProcEnviron: TERM=xterm PATH=(custom, no user) LANG=C.UTF-8 SHELL=/bin/bash ProcFB: ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.11.0-49-generic root=UUID=570c046d-9998-4858-8aaa-786b6dc160bc ro console=tty1 console=ttyS0 RelatedPackageVersions: linux-restricted-modules-5.11.0-49-generic N/A linux-backports-modules-5.11.0-49-generic N/A linux-firmware N/A RfKill: Error: [Errno 2] No such file or directory: 'rfkill' SourcePackage: linux UpgradeStatus: Upgraded to hirsute on 2022-07-17 (0 days ago) dmi.bios.date: 04/01/2014 dmi.bios.release: 0.0 dmi.bios.vendor: SeaBIOS dmi.bios.version: 2:1.10.2-58953eb7 dmi.chassis.type: 1 dmi.chassis.vendor: QEMU dmi.chassis.version: pc-i440fx-focal dmi.modalias: dmi:bvnSeaBIOS:bvr21.10.2-58953eb7:bd04/01/2014:br0.0:svnOpenStackFoundation:pnOpenStackNova:pvr19.0.4:sku:cvnQEMU:ct1:cvrpc-i440fx-focal: dmi.product.family: Virtual Machine dmi.product.name: OpenStack Nova dmi.product.version: 19.0.4 dmi.sys.vendor: OpenStack Foundation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1981939/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
