Hi Kovid,
sorry to hear that.
Now I try to downgrade to the last version working properly on my old server - 3.7.
But I cannot install it because of this error:
Downloading tarball signature securely...
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "<string>", line 800, in script_launch
File "<string>", line 756, in main

File "<string>", line 669, in download_and_extract
File "<string>", line 653, in get_tarball_info
File "<string>", line 629, in get_https_resource_securely
__main__.HTTPError:
https://code..calibre-ebook.com/sign...686.tgx.sha512 returend an unsupported http response code: 404 (Not found)
Seems like the signature for the tarball is missing.
Any clues?
Regards,
Sebastian
