Hey @JimGlass thanks for the feedback, we’re investigating the curl dependency issue here ( Mailspring 1.17.1 can't connect to the network at all, /lib64/libcurl.so.4: no version information available (required by /usr/share/mailspring/resources/app.asar.unpacked/mailsync.bin) ) and I’ll let you know when it’s resolved.
We did recently add Fedora 43 to our automated tests to avoid problems like this in the future ( Move Windows dependencies to vkpkg for OpenSSL 3.6, latest libcurl, i… · Foundry376/Mailspring-Sync@3b963ed · GitHub )
Also I really appreciate your patience - in the January release of Mailspring we switched from bundling static copies of all of Mailspring’s linux dependencies to using the system versions. It’s an important change that’ll help us stay on top of security patches and updates (the previous release used a bundled version of curl from 2016), but is pretty tricky to build and ship in a way that runs across all major linux distros. We’ll keep you posted!
