This is feedback on the Support article related to Linux, but not the Linux version of 1Password itself. I wasn't sure how to file article feedback.
The How to keep 1Password up to date page lacks instructions on Linux.
I got here by asking a different question. I wanted to fill out the additional information section at the bottom of the Support Community question form. I wasn't able to find the 1Password Linux version number from the UI, so I clicked the How to find 1Password version? link under the field. It took me to the page above. It was not able to solve my problem.
I was able to use the
snap -info 1password command to get what I needed. It would be nice to others to have that listed. I don't know if there are more official release channels for Linux, but Snap would be a great start to list instructions for.
1Password Version: 8.1.1
Extension Version: 2.0.5
OS Version: Ubuntu 21.04
