The problem is if you have LibreOffice installed as a snap and try to open an attachment in Thunderbird, LibreOffice will generate an error message saying that it can open the file because it does not exist (in reality it does exist but LibreOffice can't read it, so the message is a bit misleading).
This is not a Thunderbird bug as the same thing happens if you try an open a file via Firefox (i.e. you click on a link to download a spreadsheet and select Open With: LibreOffice Calc). If you have LibreOffice installed via apt then you can open files via Thunderbird and other applications, presumably because the .deb version is not confined in the same way as the snap. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1881603 Title: [snap] Cannot open attached file from e-mail To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1881603/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
