The error message clearly says that the process is trying to create the file
/data/data/com.termux/files/usr/include/proc/version.h.dpkg-new but it exists already.
.dpkg-new files are generally created by
dpkg (which is run by
apt) to unpack the updated files near the old files. When everything has been successfully unpacked, they are renamed over the old files.
Quoted and adapted from https://raphaelhertzog.com/2011/07/18/deciphering-one-of-dpkg-weirdest-errors-unable-to-open-pathtofoo-dpkg-new/.
However, in your case, another version of that file exists xe2x80x93 most likely itxe2x80x99s been kept from a previous
dpkg run. This can happen due to an interrupted
dpkg run or the file is kept to manually solve conflicts.
If you donxe2x80x99t need the file anymore, delete (or rename) it and run
apt in your case) again.
