Is there a reason why you installed the package from the website? It’s better to install using your system’s package manager, or using pipx. Manual installation is rather difficult.
See this article.
@tatsumoto, there is nothing particularly difficult about it: it is just an archive with files, one of which is executable. Like DOS and Windows users would do unless there is an installer.
You just need to know how to unpack an archive and how to start a file. Unless you have /home mounted with noexec, which is not the case here.
@tracker, it seems that you don’t know where your collection is located, which might mean that you haven’t done backups yet. Nothing custom is stored in the directory you created by unpacking the Anki package, so you can just start the new version, and even start an older version again. But you must make backups frequently even if you don’t update.
Yes, of course. It is difficult to update the installed package. I recommended using a package manager because it automates everything. You install the package once, and then the package manager checks and installs updates without requiring manual interaction.
Thanks. I exported my collection as a .colpkg file, which I think is the recommended way of backing up everything, including media. Is that right? Should I back up ~/.local/share/Anki2/User 1/ too? @chrislg I did what you suggested, and I’ve successfully updated anki. Thanks.
