I would do the follwoing: =================== 1. - assuming your old profile named "1tfov4t1.default" ! - restore your backuped .thunderbird so that the directory contains one directory and two files: 1tfov4t1.default installs.ini profiles.ini the variables in the two *.ini for Path= and Default= should be set to "1tfov4t1.default" ! 2. run the chown and chmod commands from my previous comment, so that the rights and ownship are correct. - I don't know how you backuped and restored .thunderbird, so I only want make sure that a possible ownership/rights mis-setting does NOT introduce more trouble - 3. rpm -qa| grep thunderbird to see what is installed regarding thunderbird 4. sudo dnf remove < the file(s) you see from step 3.> 5. go to https://koji.fedoraproject.org/koji/packageinfo?packageID=39 go in the directory/link for the lastest thunderbird-60.8.0.x for your fedora-version (30 ?) it should be https://koji.fedoraproject.org/koji/buildinfo?buildID=1310886 60.8.x.y NOT 68.x.y !!! 6. download the package(s) you had seen in step 3. for your cpu-architecture (x86_64 ?) that could be: thunderbird-60.8.0-1.fc30.x86_64.rpm thunderbird-wayland-60.8.0-1.fc30.x86_64.rpm 7. go to the directory where you download the packages (~/Downloads ?) 8. run in an terminal sudo dnf localinstall ./thunderbird* 9. open your thunderbird from the gnome menu 10. check if all your data are in place and complete (calendar, mails, adressbook) if this is the case or if you got any trouble please report ! what have we done so far ? restore to the old state BEFORE update/upgrade and verify if all data complete ! next step is to export all data, update to the newer thunderbird and re-import the data. where I got one point of trouble: migrating the mails !!! I for myself would do it via imap account, but ... @home user, what typ of mail account do you have at your mail provider (pop or imap) ? is imap something you know ? Anyone out there who has experiences with mail migration, esp. without going via imap account, a tool to ex-/import mails from TB, etc. ??? _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
