Hang when checking package integrity on update

[David-Malaguti-Bose]

• Fresh install of MSYS2 64bit
• After install, ran 'pacman -Syu' per the setup instructions
• Restarted shell as instructed
• Ran 'pacman -Su' to continue updates

Hangs on 'checking package integrity'. I let it run for >1 hour and no change or further output, process has to be killed. Is there any additional information I can provide?

$ pacman -Su :: Starting core system upgrade... there is nothing to do :: Starting full system upgrade... resolving dependencies... looking for conflicting packages...

Which Windows version? Which anti-virus and/or firewall software?

[valeriuo]

Same here. Win10 Enterprise (version 1803, build 17134.228). Sophos antivirus.

[valeriuo]

The pacman subprocess that does the integrity checking busy waits on something, taking a whole core. I ran it with --debug and --verbose and it didn't spit any errors. If you kill it by hand, the main process goes to checking the next package, by spawning a new subprocess that will hang as well. Do this for 53 times (kill it) and you'll get to the end of a successful installation.

[valeriuo]

The pacman subprocess seems to be hanging between these two steps:

debug: validity: full; reason: Success
debug: key: <key-fingerprint>, Alexey Pavlov (Alexpux) <alexpux@gmail.com>, owner_trust unknown, disabled 0

[David-Malaguti-Bose]

My apologies for the delayed response. My setup is the same as @valeriuo, including Sophos.

[StarWolf3000]

Does it run with Sophos temporarily disabled?

[tcarlisle2012]

Just an FYI, found this today and killing the process and disabling Avira real-time protection temporarily and re-trying did work as expected.
