Is there any (good) SQLite GUI for Linux?

Tried Sqliteman? Look for sqliteman in your package manager. It is stable, so should be broadly available.

I've been using sqlitebrowser, it is a really good options. Though probably not the only one!

On Ubuntu, it is available in the default package repositores.

I've used the SQLiteStudio for working with sqlite3 database. It looks very well.

The project is maintained (as of 2018). For some reason it is not available in common packages repositories.
