Bash: declare: PROMPT_COMMAND: not found (ERROR)

Scotty_Trees · October 5, 2021, 5:26pm

Greetings lovely community,

Just ran some updates earlier today and I noticed whenever I open up my favorite terminal Tilix, I get the following error on the very first line:

bash: declare: PROMPT_COMMAND: not found

Screenshot from 2021-10-05 12-23-56

Normally, that error on the first line shouldn’t be showing up at all, so I thought this was odd. I don’t know if it might help at all, but in my .bashrc file, the only change I’ve done there is added neofetch on the last line to make it autostart whenever I open a new Tilix terminal.

If it helps at all, I’ll post my .bashrc file and also my pacman transaction history from the last 24 hours in case any packages might be the cause of this. If I need to file a bug anywhere please let me know and if you need any other sort of logs from me please let me know. I don’t know if anyone else is experiencing this issue from today’s updates as well or if it’s just me?

My .bashrc file:

#

[[ -f ~/.welcome_screen ]] && . ~/.welcome_screen

Just a quick update, I did some searching around and stumbled onto this recent thread from a few days ago: https://bbs.archlinux.org/viewtopic.php?pid=1996345

While I didn’t understand what their solution in that post was (they just posted a link to what looked like a merge request maybe?), I did see a comment over there mentioning a setting called “Run command as login shell” which is an option inside Tilix preferences. Pretty sure it’s an option in Gnome Terminal as well. For whatever reason I had that option turned on, and by turning it off, the error message at the top of my terminal window went away. So while not a true “fix” per se, since the underlying issue is more than likely still present, at least for now I don’t see the error message show up anymore.

If the “Run command as a login shell” is turned off here, the error won’t show:

With the option from above turned off, the Tilix terminal functions again just like how I’d like it to:

@dalto Like I said, I don’t know if this is a solution or more just a workaround, but for now that’s all I got!

dalto · October 6, 2021, 6:56pm

From reading that topic, it looks like the actual fix has been committed in vte so when that fix makes it into an actual release of vte it should resolve the long-term issue.

Scotty_Trees · October 6, 2021, 7:12pm

Yeah thanks for checking that out and verifying that, very much appreciated. I’ll keep my eye out for any new vte or vte-common package update and see if the issue gets resolved from the update
