Public bug reported: Description:
Since upgrading to Ubuntu 26.04 LTS, large file downloads (>50MB) intermittently fail with: OpenSSL error: error:0A000119:SSL routines::decryption failed or bad record mac Reproduction: # Fails (OpenSSL): curl -o /dev/null https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb # Succeeds (GnuTLS): wget -O /dev/null https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb Affected tools: curl, apt (switched to OpenSSL in 26.04), snap (tls: bad record MAC) Working tools: wget (uses GnuTLS) Environment: - Ubuntu 26.04 LTS, kernel 7.0.0-22-generic - OpenSSL 3.5.5-1ubuntu3.2 - WiFi: Realtek RTL8852AE (rtw89_8852ae) - Small downloads always succeed, large ones fail intermittently - Same file, same network — only the TLS library differs Note: Ubuntu 26.04 switched apt from GnuTLS to OpenSSL, making this a regression for apt users.
