File: '/home/qt/RTA/downloads/Jetson-public_sources-36.4.0.tbz2.tmp' has sha256 checksum '6e95abdf9195052b8d6b63777b9b1417a758248b2cf1a82c469ab75d2c4af754' when 'a99cb9176a96cff19ddeb928c9e4a2c5d5bf45787b2c2941fd3e942ee7540292' was expected
If this change is expected (e.g. you have upgraded to a new version without updating the checksums) then you can use these lines within the recipe:
SRC_URI[sha256sum] = "6e95abdf9195052b8d6b63777b9b1417a758248b2cf1a82c469ab75d2c4af754"
Otherwise you should retry the download and/or check with upstream to determine if the file has become corrupted or otherwise unexpectedly modified.
