Trying to verify new version of seamonkey, while old fashioned method works:
cd ~/Downloads
wget --no-check-certificate https://archive.mozilla.org/pub/mozi...2.38.checksums
wget --no-check-certificate https://archive.mozilla.org/pub/mozi...y-2.38.tar.bz2
cat seamonkey-2.38.checksums
sha512sum seamonkey-2.38.tar.bz2

I can't get working any of these commands:
sha512sum -c seamonkey-2.38.checksums
sha512sum -c seamonkey-2.38.checksums 2> /dev/null | grep OK
sha512sum -c seamonkey-2.38.checksums 2> /dev/null | grep "sha512 48603839 linux-i686/en-GB/seamonkey-2.38.tar.bz2"

The checksum file is in strange format:

Hi marcelp1
Last first. I do not see that the checksum file is in a strange format. The first line is a sha512 encryption.
is a md5 digest of the file.
is the sha1 encryption.
All seems fine with these values (structure wise).
On the what exactly does it give as an error, or what happens?

While the 64bit version works:
wget https://archive.mozilla.org/pub/mozi...-x86_64.MD5SUM
wget https://archive.mozilla.org/pub/mozi...-x86_64.README
wget https://archive.mozilla.org/pub/mozi...x86_64.SHA1SUM
wget https://archive.mozilla.org/pub/mozi...x86_64.tar.bz2
sha1sum -c seamonkey-2.38.en-US.linux-x86_64.SHA1SUM
md5sum -c seamonkey-2.38.en-US.linux-x86_64.MD5SUM

You have to be in the subdirectory where the files are and have the checksum file also in that subdirectory. It appears that it cannot find the actual files when you are running the shasums.

i take it you did not READ what you "copy/pasted"

do not just blindly "copy / past" things!!!

this is the folder layout ON THE MOZILLA SERVER!!!!

you did not make a folder called "linux-i686" nor did you make a folder called "en-GB" in that folder !!!


likely you downloaded seamonkey-2.38.tar.bz2 to " Downloades "

so please READ and do not just blindly "copy / past" things!!!
