I have had this version for a few years now and would like to upgrade it to 22.04 lts.

    sudo do-release-upgrade -d
    Checking for a new Ubuntu release
    Upgrades to the development release are only 
    available from the latest supported release.

deb [signed-by=/usr/share/keyrings/adoptopenjdk-archive-keyring.gpg] https://adoptopenjdk.jfrog.io/adoptopenjdk/deb hirsute main

What can I do?

    This answer will help you restore your botched /etc/os-release file (which is actually a symlink to /usr/lib/os-release).

    From your kernel version, and your previous questions, it's evident that your system is actually running Ubuntu 21.04 (Hirsute Hippo). This release is now end-of-life, and you should upgrade to a supported release ASAP.

    For unknown reasons, you have overwritten your /etc/os-release file with invalid contents - let's fix that.

    Open the file in an editor (like nano) with root privileges:

    sudo nano /etc/os-release

    Replace the entire contents of the file with this:

    NAME="Ubuntu"
VERSION="21.04 (Hirsute Hippo)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 21.04"
VERSION_ID="21.04"
HOME_URL="https://www.ubuntu.com/"
SUPPORT_URL="https://help.ubuntu.com/"
BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"
PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
VERSION_CODENAME=hirsute
UBUNTU_CODENAME=hirsute

    Save and exit.

    Now when you run lsb_release -a it should show:

    No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 21.04
Release:        21.04
Codename:       hirsute
