When portage tries to download a file from mirrors.evowise.com you get a html file, not the file requested. For example the layout file: $ ls -l .layout.conf.* -rw-rw-r-- 1 portage portage 45 Nov 5 2019 .layout.conf.mirror.bytemark.co.uk -rw-rw-r-- 1 portage portage 614406 Sep 20 10:56 .layout.conf.mirrors.evowise.com -rw-rw-r-- 1 portage portage 45 Nov 5 2019 .layout.conf.www.mirrorservice.org $ head -c 32 .layout.conf.mirrors.evowise.com <!DOCTYPE html><html lang="en">< Reproducible: Always
Looks like mirrors.evowise.com is no longer a mirror site. Sorry for wasting your time - should have checked the master list of mirrors before reporting.
