I launched emerge-webrsync: $ sudo emerge-webrsync The download started, but no progress bar was shown, so I interrupted the program execution. Next I could not more resume emerge-webrsync execution because I got the messages: $ sudo emerge-webrsync Fetching most recent snapshot Attempting to fetch file dated: 20071008 portage-20071008.tar.bz2: FAILED md5sum: WARNING: 1 of 1 computed checksum did NOT match $ The above errors does not always happen, but most times does (sorry cannot be more precise). With the above (apparenty unrecoverable) faulty situation, I did: $ ls -ahl /var/tmp/emerge-webrsync 124K -rw-r--r-- 1 root root 121K 9 ott 12:15 portage-20071008.tar.bz2 300K -rw-r--r-- 1 root root 297K 9 ott 12:12 portage-20071008.tar.bz2.1 4,0K -rw-r--r-- 1 root root 59 9 ott 11:45 portage-20071008.tar.bz2.md5sum After deleting the temporary files: $ sudo rm -f /var/tmp/emerge-webrsync/* Everything went OK and I could run again emerge-webrsync I think that if emerge-webrsync finds the snapshot file locally it should attempt to resume like emerge does - or at least allow automatic redownload.
emerge-webrsync now creates a randomly-named temp directory in ${PORTAGE_TMPDIR} and tries to clean it up before exiting.
