Can't use tlmgr following clean installation, tlmgr: Local TeX Live (2021) is older than remote repository (2022)

Question

I followed the instructions according to https://tug.org/texlive/quickinstall.html

I am using Ubuntu 22.04.1 LTS on Windows 11 WSL.

I cannot get past this error when doing anything with tlmgr. Beforehand, I needed to run tlmgr init-usertree.

$ sudo tlmgr install adjustbox
(running on Debian, switching to user mode!)
(see /usr/share/doc/texlive-base/README.tlmgr-on-Debian.md)

tlmgr: Local TeX Live (2021) is older than remote repository (2022).
Cross release updates are only supported with
  update-tlmgr-latest(.sh/.exe) --update
See https://tug.org/texlive/upgrade.html for details.

$ sudo tlmgr update --self
(running on Debian, switching to user mode!)
(see /usr/share/doc/texlive-base/README.tlmgr-on-Debian.md)

tlmgr: Local TeX Live (2021) is older than remote repository (2022).
Cross release updates are only supported with
  update-tlmgr-latest(.sh/.exe) --update
See https://tug.org/texlive/upgrade.html for details.

As far as I can tell, I have installed the most up-to-date version:

$ tex --version

$ tlmgr --version

tlmgr using installation: /usr/local/texlive/2022
TeX Live (https://tug.org/texlive) version 2022

I have tried removing everything TeX and trying again but receive the same error. Any help is appreciated!

Answer 1

I found the silly error, my version of tlmgr was in fact outdated, but only when using sudo:

$ tlmgr --version
tlmgr revision 63068 (2022-04-18 07:58:07 +0200)
tlmgr using installation: /usr/local/texlive/2022
TeX Live (https://tug.org/texlive) version 2022

$ sudo tlmgr --version
tlmgr revision 60693 (2021-10-04 04:24:25 +0200)
tlmgr using installation: /usr/share/texlive
