In case anyone else hits this problem and is wondering about the root cause, it seems to be because snaps generally can't access data from other applications, so when Thunderbird drops a file into /tmp LibreOffice can't "see" it. This isn't unique to LibreOffice, it causes problems for other snaps as well (e.g. Chromium).
This doesn't happen with the non-snap version of LibreOffice distributed through the Ubuntu archive and available via `apt install`, so switching to that is a workaround, albeit at a lower version (6.4.2 instead of 7.0.2.2). There are a few Ask Ubuntu posts with additional information and other workarounds: https://askubuntu.com/questions/1123537/cant-open-file-attachment-with- libreoffice-snap https://askubuntu.com/questions/1046890/libreoffice-cant-access-tmp- files-in-18-04 https://askubuntu.com/questions/1215305/how-can-i-grant-a-snap- application-access-to-tmp-via-command-line -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
