There are issues with the APT repository - https://software.intel.com/content/www/us/en/develop/articles/installing-intel-free-libs-and-python-...:
# apt-get update [...] E: Failed to fetch https://apt.repos.intel.com/mpi/dists/all/InRelease 403 Forbidden [IP: 126.96.36.199 443] E: The repository 'https://apt.repos.intel.com/mpi all InRelease' is no longer signed. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details.
apart from the 403 HTTP code, the repository itself is signed with a GPG key which has expired in 2019:
# apt-key list [...] pub rsa2048 2016-09-28 [SC] [expired: 2019-09-27] BF43 85F9 1CA5 FC00 5AB3 9E1C 1A84 97B1 1911 E097 uid [ expired] "CN = Intel(R) Software Development Products", O=Intel Corporation [...]
It seems like both problems are related.
I'm not sure whether you have replied to somebody else's post by mistake here, as the above doesn't make much sense. No proxies are involved - it's a direct network connection. The issues are server-side.
As described above (formatting got stripped for some reason), the issues are:
- expired repository GPG key
- 403 HTTP error code while running 'apt-get update' (might be related to the issue above)
I'm afraid not, the issue is still there:
