eosinstaller does not work for all. There is no documented way to collect a log but, untested by me, was suggested
Please also check the CLI install page Install /e/OS on a Fairphone FP4 - “FP4”.
The manual install method includes this in Requirements
Check that
adbandfastbootare enabled on your PC. If not you can find the setup instructions here
- Note the above requirement is not noted for the eos-installer (as platform-tools are provided in the ROM), but other similar installers do link the following idea.
The correct method to have platform-tools working nicely on Mint may be involved in your problem, idk cryptic clue.
Many have found it easier to follow CLI install method than troubleshoot the Web Installer.
