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 Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1881603 Title: [snap] Cannot open attached file from e-mail Status in libreoffice package in Ubuntu: Confirmed Bug description: I installed the LibreOffice snap to get a newer version compared to the apt package. When I receive a LibreOffice document as attachment and try to open it from Thunderbird, I get the following error message: """ /tmp/mozilla-antoine0/mydoc.docx doesn't exist """ I don't understand the point of restricting filesystem access from a word processor. At least this is a clear regression from the apt package.
